LANXESS to showcase new sustainable solutions for e-mobility at K 2022
Source:Adsale Plastics Network    Editor:JK    Date:23.Jun.2022

Under the motto “Quality Works”, LANXESS will present its material developments and new processes and technologies for the plastics industry at K 2022. Sustainable products and system solutions for the rubber and polyurethane industries will also be on display, as well as colorants and intermediates for the polymer sector.


The company's focus topics for this year’s trade fair are electromobility and sustainability. “We want to play an active role in the transformation of the economy and global value chains towards a more sustainable world,” stated Dr. Hubert Fink, member of the LANXESS Board of Management.


Adding sustainable product variants to Tepex composites


The High Performance Materials business unit focuses on sustainable material and lightweight solutions. Main areas are materials and component concepts for consistent lightweight construction in the future market of electromobility.


For example, lightweight structural components based on the continuous fiber-reinforced composites of the Tepex brand in the field of batteries for passenger cars.

Besides, the business unit will present new Tepex composites based on recyclates or bio-based raw materials. One example here is Tepex dynalite Scopeblue 813, which has recently been launched on the market and is produced from flax fibers and polylactic acid.


Latest Tepex thermoplastic composites made from recycled or bio-based raw materials.

Also on show will be a Tepex dynalite with a polyamide 6 matrix that is produced starting from “green” cyclohexane and therefore consists of well over 80% sustainable raw materials.


When the matrix plastic is reinforced with continuous-fiber fabrics, the resulting semi-finished products exhibit the same properties as comparable, equivalent products that are purely fossil-based.


The semi-finished products with a green matrix are, therefore, suitable for applications in structural lightweight design that are typical for Tepex dynalite, such as front-end carriers, seat shells, or battery consoles.


New flame-retardant PBT compound for high-voltage connectors


Another focus is on tailored solutions for the increased requirements in electric vehicles, for example in the powertrain or charging infrastructure. Here, plastic components are often exposed to higher temperatures and at the same time very strong electrical currents and voltages.


LANXESS has developed a new halogen-free flame-retardant and hydrolysis-stabilized PBT compound for these high-voltage connectors. It can be colored in bright colors, such as orange.

The compound is a first representative of the new Pocan BFN HR product range and is characterized by a high level of volume resistance and dielectric strength. For instance, the latter is proven well over 30 kilovolts per millimeter at temperatures of up to 140°C.


In the CTI test, the material achieves CTI A 600, the highest class possible according to the standard. This makes it highly tracking-resistant, which reduces the risk of short circuits and defects caused by creepage currents.


Its good flame-retardant properties are demonstrated by the fact that it passed the UL 94 flammability test of the US testing institute Underwriters Laboratories Inc. with the excellent classification V-0 with a test specimen thickness of 0.75 millimeters.


Bio-based low free monomer prepolymers for PU applications


The Urethane Systems business unit will, at the same time, showcase its extensive product range for the polyurethane industry. It is designed to increase sustainability along the entire value chain.


The wide portfolio includes low free monomer technology (Adiprene LF), innovative Adiprene Green prepolymers with high bio-based content, novel hot cast and cold cure systems for processing with reduced energy consumption, and water based lacquers, to meet high requirements of modern automotive interiors.


Under the brand name Adiprene Green LF, the company provides a range of bio-based low free monomer prepolymers for polyurethane CASE applications.

With Adiprene LF, LANXESS offers a wide range of prepolymers with less than 0.1 wt.% free MDI (methylene diphenyl diisocyanate) and other free isocyanates. The range got successfully extended for the use in hot melt adhesives, like in the automotive, construction, electronics and bookbinding industries.


In CASE (Coatings, Adhesives, Sealants, Elastomers) applications, thermo plastic polyurethanes can be processed more efficiently by adding the modifier Modulast PUR. The use of polyols and isocyanates can be reduced, while the physical properties are maintained and often even improved.


This not only reduces overall raw material costs. The entire production process also becomes more efficient, benefiting from lower temperatures during processing and resulting in shorter cycle times.


Colorants, flame retardants and additives also on stage


Furthermore, LANXESS’ Polymer Additives and Inorganic Pigments business units offer the plastics industry high-performance, sustainable colorants for direct coloration.


LANXESS will also showcase its colorants, flame retardants and additives at the trade fair.

In electromobility, for example, the color orange is a mandatory safety feature for high-voltage plastic components. This is where Macrolex Orange HT comes into play. Its comprehensive properties meet the high safety and performance requirements for electric cars.


With brominated and phosphorus-based solutions, the company offers comprehensive ranges of organic flame retardants. The polymeric and reactive flame retardants reduce the release of additives from polymers, thus contributing to environmental and health protection without compromising fire safety.


Due to their high efficiency, brominated flame retardants are widely used in the construction and electronics industries. In addition to effective fire protection, phosphorus-based flame retardants offer other advantages such as good processability and high elasticity in PU and PVC systems.


A wide range of additives for the rubber processing industry will be presented by the Rhein Chemie business unit. These include predispersed chemicals, processing promoters and vulcanization and filler activators.


With the aim of advancing sustainability, the focus will be on not only rubber production but also the manufacture of high-quality, long-lasting rubber products designed for a whole range of applications such as tires, hoses, seals, profiles, and drive belts.
