Highly integrated hybrid front-end module with adjustable air flow

Smartly designed with easy-flowing polyamide

Ø  Greater flexibility during processing

Ø  Smaller injection molding machines with lower clamping forces

Ø  Wall thickness reduced by 20% in component areas subject to lower loads

Cologne – Thermoplastics with easy-flowing properties are usually somewhat more expensive than comparable standard materials; however, they offer advantages that ultimately pay off in terms of processing, production costs and freedom of design. This can be seen in the highly integrated bolster produced in plastic-metal composite technology (hybrid technology) for the Ford Kuga SUV. In addition to steel panels, the production of the highly loaded structural component includes polyamide 6, the easy-flowing, fiberglass-reinforced Durethan BKV30H2.0EF from LANXESS. The bolster and the fully assembled front-end module were developed and are produced by Montaplast GmbH, a global system supplier of the automotive industry, which has its headquarters in Morsbach, Germany.

Ulrich Dajek, hybrid design expert at LANXESS, explains: “Our easy-flowing polyamide 6 can be processed at lower injection pressures. For this reason, smaller injection molding machines with lower clamping forces can be used in the production of the hybrid bolster. This has a positive effect on the machine running costs and allows greater flexibility in terms of machine selection and production planning.”

Four integrated active grille shutters

The bolster houses an actively controllable unit consisting of four active grille shutters that ensure a demand-oriented supply of air to the engine cooling system. The bolster contains reinforcing metal inserts at the sides and in the upper chord. The latter accommodates the highly loaded hood latch. The main task of the hybrid design is to support the cooling systems and hold them in position. Numerous additional functions are also integrated in the bolster – such as guides, mounts for the adjustment drive and fasteners. “Our development engineers have succeeded in integrating all these elements, functions and interfaces so that the functional and load requirements are met. At the same time, they have ensured that the entire front-end module can be produced in different region-specific versions in an automated high-volume process in a cost-efficient manner,” comments Horst-Dieter Haltrich, Product Development Team Leader at Montaplast.

Direct threaded connections with greater stability thanks to polyamide 6

As a plastic component for the hybrid bolster, polyamide 6 has two main advantages over the possible alternative material, polypropylene (PP). The first advantage is that the component contains several direct threaded connections; these are more cost-efficient than using additional metal inserts. The threaded connections designed using polyamide 6 are significantly more stable, have a longer service life and are more reliable than with PP. The second advantage of polyamide is that it withstands the thermal loads that arise when the grille shutters are closed, in contrast to PP.

Easier to achieve filigree, thin-walled component areas

Due to the high flowability of polyamide 6, component areas with filigree geometries can be designed with thinner walls. “It was possible to reduce the wall thickness by around 20% in the areas subject to lower loads. Compared to a standard polyamide 6 with the same fiberglass content, this results in an appreciable weight saving,” according to Dajek. Due to the lower filling pressure, another benefit of the easy-flowing material is that components with lower stresses can be produced, minimizing the distortion.

Extensive HiAnt services

Ford, Montaplast and LANXESS worked closely together over the entire development process for the hybrid bolster right up to the start of series production. LANXESS also brought in its HiAnt engineering service. In one of several engineering studies, a component topology analysis was carried out to provide suggestions for the design and position of the reinforcing polyamide ribs that took account of the relevant load cases. Various calculations and simulations, such as analysing the rigidity of the radiator mount and the dynamic stability and noise vibration harshness (NVH) of the bolster, were also highly challenging. The load-bearing capacity of the metal-reinforced latch area (hood latch) as well as several insurance-relevant load cases – such as lower leg impact tests for pedestrian protection or the behavior of the overall assembly in the case of minor collisions, e.g. knocks while parking – were also simulated. In addition, LANXESS carried out tests on the prototype and series-production part to the specifications of Ford. Dajek: “For example, we allowed the complete assembly to ice up in a climatic chamber and tested the reliable opening and closing of the grille shutters.”

LANXESS launches Group initiative for e-mobility

Ø  Group wants to further exploit market potential for e-mobility and battery technology

Ø  New management and realignment for Rhein Chemie business unit

Cologne – Specialty chemicals company LANXESS is aiming to further strengthen its market position in technologies relating to new mobility: In the future, all activities in this area will be managed by a Group initiative for e-mobility. The new strategy unit will be headed by Philipp Junge (44), currently head of the Rhein Chemie business unit, as of August 1, 2020.

“Modern mobility is one of the most dynamic growth sectors worldwide. LANXESS has a lot to offer here, from our high-tech plastics for electric vehicles to specialty chemicals for batteries. We want to expand this offering significantly, coordinate it more precisely and position it even stronger in the market,” explains Anno Borkowsky, member of the LANXESS Board of Management.

The Group's high-performance plastics are used in electric vehicles, for example for lightweight car bodies or battery housings. They also have great potential in the infrastructure for e-mobility, such as charging stations, and in sensors, displays and control units for autonomous driving.

In addition, LANXESS is a leading manufacturer of numerous specialty chemicals that modern battery systems cannot do without, such as phosphorus chemicals, hydrofluoric acid and flame retardants. Furthermore, the Group is working on the commercial production of lithium, the key component of lithium-ion batteries. At its site in El Dorado, United States, LANXESS recently commissioned a pilot plant together with its partner Standard Lithium. The companies aim to use the plant to extract battery grade lithium from brine produced during the bromine production process at LANXESS.

Rhein Chemie: Focus on rubber additives

Jens-Hendrik Fischer (41) will be the new Head of the Rhein Chemie business unit, succeeding Philipp Junge. Fischer is currently responsible for the business with antioxidants and accelerators for the rubber industry within the LANXESS Advanced Industrial Intermediates business unit. It is planned that these products will be managed under the umbrella of Rhein Chemie, which already offers numerous specialty rubber additives. “Rhein Chemie would thus become the central business unit at LANXESS for products for the rubber industry,” says Borkowsky.

Wild bees love red pigments from LANXESS

Ø  Bayferrox pigments for bee hotels from Krefeld-based concrete manufacturer

Ø  Bauhaus-style nature conservation

Ø  A statement piece in bee-friendly gardens or green cityscapes 

Krefeld – The square is red, the circle is blue and the triangle is yellow. This connection can be traced back to the color and shape theory of the Bauhaus artist Wassily Kandinsky. The Krefeld-based concrete manufacturer Grellroth has consistently implemented this style in the design of its bee hotels. The nesting aids are made of self-compacting concrete, with edge lengths of around seven centimeters each, and are available as a red cube, a blue cylinder and a yellow pyramid. Weather-stable inorganic pigments from LANXESS ensure long-lasting color. According to Diana Schmidt-Rothmeier, Managing Director of Grellroth, wild bees particularly like the red variant, which is colored with the pigment Bayferrox 130. “The red hotels are always the first to be filled,” says the graduate designer.

The nesting aids, which are marketed as “beehaus,” are available not only in red, blue and yellow, but also in a light concrete gray. The iron oxide yellow pigment Bayferrox 920 and the black pigment Bayferrox 360 from LANXESS are also used to color the concrete.

Small works of art

Grellroth employs craftsmen, technicians and designers who conceptualize and design furniture and objects made of concrete and manufacture them as one-off items or in small-scale series. When it comes to the beehaus, the concrete manufacturer places particular emphasis on sustainability. Fragments and leftovers from the production of larger components are mixed with high-quality white cement, easily dispersible pigments and concrete additives and poured into specially created molds to create durable bee houses – all by hand.

“Developing and manufacturing the polyurethane molds for this purpose was a challenge in itself, because the necessary draft angles in the narrow tubes require a certain expertise,” explains Schmidt-Rothmeier, who previously worked for the automotive industry for several years and now contributes the knowledge of materials she gained there to the implementation of new ideas for concrete. For the good flow characteristics of self-compacting concrete, Grellroth uses an in-house formulation with a finely matched mixture of additives. “The concrete flows in like honey and comes out almost pore-free,” says Schmidt-Rothmeier. “This means that even difficult geometries can be realized and there is no need to shake the molds for venting,” explains the designer.

“State-of-the-art concretes such as self-compacting concrete are based on complex formulations, the constituents of which must be perfectly matched to meet requirements. This must also be kept in mind when iron oxide pigments are used, whether for small or large structures,” says Oliver Fleschentraeger, Market Segment Manager for Construction in the Inorganic Pigments business unit at LANXESS.

The readily dispersible iron oxide pigments from LANXESS give the concrete a uniform and durable shade. The small works of art are lightfast and weatherproof throughout, rather than just colored on the surface.

Survival support for recluses

While honey bees live exclusively in their thousands in beehives, wild bees are predominantly recluses. The worldwide more than 30,000 different species of wild bees have differing requirements for their nesting places. The beehaus offers an excellent place for the endangered wild bees to nest and hibernate.

The various diameters of the holes attract different species of wild bees. They lay out their brood cells in the narrow and smooth tubes and provide the eggs with nectar and pollen. The bee then seals the tube with mud until the larvae hatch in spring and open it to fly out. The bee hotels can then be cleaned easily with a thin brush.

Easy to clean and robust

Insect hotels are usually made of wood or plant stems. However, bamboo tubes and other organic nesting boxes are often full of splintered parts that can injure the bee and its delicate wings. The advantage of concrete as a material is that the walls are nice and smooth. In addition, concrete is an extremely robust material and does not require any special care. Since the material does not rot due to fungal attack – unlike some wooden nesting boxes – the houses have a long life. The inorganic pigments are extremely weatherproof and ensure that the colorful nature is retained for a long time. The concrete “blocks” do not require any upkeep, and make a small contribution to the conservation and reproduction of bees, which are key pollinators for agriculture and garden owners.

For children, observing wild bees is fascinating and promotes awareness of nature and animals. Since the insects have neither a queen nor honey to protect, they are not aggressive and do not sting.

It is important to place insect hotels so that the opening faces south and, if possible, to hang them in a sunny spot that is protected from wind and rain. Having bee-friendly plants in the surrounding area is also helpful to provide them with food.

Detailed information about the bee hotels, which can be viewed in the great outdoors from mid-May to the beginning of October in the “Garden of Opposites” at the 2020 State Horticultural Show in Kamp-Lintfort, can be found on the website grellroth.de.

Sustainable supply chain

The sustainably produced LANXESS pigments used for the coloring come from the immediate vicinity of Grellroth Betonmanufaktur – the world’s largest production facility for inorganic color pigments is just ten kilometers away as the crow flies. Specialty chemicals company LANXESS has been producing iron oxide and chrome oxide pigments for many applications at its Krefeld-Uerdingen site for over 90 years. LANXESS pigments are used around the world to color concrete, coatings, inks, paper and plastics.

The Bayferrox iron oxide pigments support the requirements of sustainable building and improve the classification of construction materials manufactured in resource-preserving processes through rating systems such as LEED (Leadership in Energy and Environmental Design) and DGNB (German Sustainable Building Council). As a result, LANXESS is the only pigment producer in the world to be SCS-certified. SCS Global Services Scientific Certification Systems, Inc. – one of the leading independent certification companies – has confirmed the large proportion of recycled raw materials in the production process for LANXESS iron oxide pigments.

At its most important site in Krefeld-Uerdingen, the business unit uses the entire value chain of iron oxide production – from synthesis to packaging. More detailed information can be found at bayferrox.com/en/.

LANXESS increasingly making use of the circular economy for plastics

New Durethan ECO polyamide product range featuring fibers from waste glass

Ø  Certified by ecoloop in accordance with the mass balance method

Ø  Conserving raw materials, less greenhouse gases

Ø  Material properties identical to those of conventional virgin quality material

Ø  Range of products containing a high percentage of recycled material continues to grow

Cologne – Specialty chemicals company LANXESS is increasingly making use of recycled raw materials in the production of its thermoplastic compounds and composites. “We want to help make the switch from a throw-away society to a circular economy. Our goal is to make more and more of our plastic products sustainable so that we can make our growth less dependent on the consumption of finite resources, improve our carbon footprint and protect the environment,” explains Dr. Guenter Margraf, global product manager at the company’s High Performance Materials (HPM) business unit.

Durethan ECOBKV30H2.0, ECOBKV35H2.0 and ECOBKV60XF are the most recent examples of products made in line with this strategy. Recycled fibers manufactured from waste glass make up 30%, 35% and 60% by weight respectively of these three new polyamide 6 compounds. Ecocycle, an independent inspection company, has examined the amount of recycled material in each compound and the long-term use of the glass waste stream using the mass balance method and awarded an ecoloop certificate in accordance with ISO 14021:2016. The glass comes from waste left over from glass fiber production (post-industrial recycling).

Mass balance method comes with benefits for processors

The mass balance approach is derived from an initiative launched by the non-profit Ellen MacArthur Foundation and is employed by companies around the world, including a number of plastic producers, for chemical recycling of post-industrial and post-consumer waste. With this process, recycled raw materials are incorporated into production together with the petrochemical or mineral feedstocks commonly used otherwise and then arithmetically allocated to the end product. The basic principle is similar to the way in which environmentally friendly electricity or gas is fed into the electricity grid or gas network. The amount of sustainably produced energy in the electricity grid rises with demand, although it is not possible to make any physical distinction between the sources of energy at single-household level. One point in the mass balance method’s favor is that the characteristics of the finished product – such as a polyamide compound reinforced with recycled waste glass fibers – are identical to those of virgin quality material. In other words, using the method does not mean sacrificing any product characteristics. “That means that an injection molder can process the compound using existing facilities just like the conventional product – and enjoy the sustainability benefits of the certified product at the same time,” says Margraf.

Focus on automotive applications

HPM’s primary target for the three new compounds is the automotive industry. As Margraf explains, “For instance, Durethan ECOBKV60XF offers exceptional strength and rigidity, which makes it suitable for manufacturing structural components such as front ends, pedal bearing brackets and A-, B- and C-pillars, as well as lightweight battery trays for electric vehicles.”

Polyamide 6 with reduced carbon footprint currently in development

HPM is going to be gradually increasing the number of ECO product types certified in accordance with the mass balance method. For example, it is planning to launch a new polyamide 6 with a glass fiber content of 30 percent and a reduced carbon footprint. The caprolactam required to produce this more environmentally friendly polyamide 6 is based on a selection of petrochemical raw materials which support this concern.

Waste glass fibers – a precious commodity

HPM is not currently using waste glass fibers from end-of-life components (known as post-consumer recycling), but does view them as a particularly sustainable raw material for use in manufacturing new glass fibers. After all, they do offer similar benefits as the domestic collection and recycling of glass containers, which have been practiced successfully for quite some time. Waste glass melts at lower temperatures than the raw materials used in manufacturing glass fibers. It therefore makes it possible to save energy and thus lower CO2 emissions. “Using waste glass cuts down on the use of resources as well, because it saves glass raw materials,” says Margraf. “It also means there’s no need to dispose of the waste glass.”

LANXESS _It's the combination that does it

Ø  LANXESS expertise and technologies for wastewater treatment

Ø  Combination of ultrafiltration/reverse osmosis for removing suspended solids from refinery wastewater

Ø  New and further development of software for the success of our customers

Cologne – Membrane techniques have enormous potential for water treatment. “The removal of harmful or troublesome trace elements as completely as possible during water treatment is more important today than ever before – and is also indispensable for responsible wastewater management,” said Alexander Scheffler, head of Marketing in the Liquid Purification Technologies (LPT) business unit at specialty chemicals company LANXESS. For example, ultrafiltration (UF) and reverse osmosis (RO) can be combined perfectly to treat wastewater flows containing suspended solid matter. “After reverse osmosis, the water quality is almost equivalent to that of drinking water. Depending on the process used, the pH value still has to be adjusted or the ammonia has to be removed using ion exchangers,” explained Dr. Jens Lipnizki, head of Technical Marketing for Membranes in the LPT business unit.

From the slurry tank to the shop counter

One example of an RO-based process is the treatment of pig slurry, as has been successfully practiced in decentralized systems in the Benelux countries for years. In the first step, a physicochemical treatment is applied in which ferrous sulfate and a flocculating agent are added to the slurry. The solid matter is separated by means of a strainer and sold in granulate form as a natural organic garden fertilizer. The remaining liquid phase is concentrated further by reverse osmosis. In combination with an ion exchange process, the majority of ammonium ions can also be removed from the permeate.

Slurry treatment results in a granulate and a concentrated liquid phase. In addition, clean water is produced, which can easily be fed into the water cycle.

Using a combined process to remove solids and borate content

Together with the French company Polymem SA, Toulouse, LANXESS recently completed a project for an Italian oil company as part of a sales partnership. In this project, a combination of UF/RO is used to remove suspended solids (total suspended solids, TSS) and borate from the wastewater of an oil refinery in Apulia, southern Italy, thus making it available for reuse within the process. The solids can be completely removed, while the borate content falls by around 97 percent. The low-pressure process also stands out due to the relatively low investment required as well as its equally low energy consumption. Discussions concerning a further expansion of the system are currently ongoing.

Since mid-2018, LANXESS has been selling Gigamem neophilic hollow fiber membranes from Polymem, one of the world’s leading manufacturers of high-quality UF membranes and systems for drinking water and wastewater applications. This way, the German specialty chemicals company added ultrafiltration to its existing technology portfolio for water treatment.

Further development of software for the success of our customers

“The swift and reliable design of the UF/RO system in Italy also impressively demonstrates the performance of the new LewaPlus module for calculating ultrafiltration processes. This module is now an integral part of our LewaPlus design software, version 2.1 of which was released in March 2020,” emphasized Lipnizki.
