AUTOMOTIVE | COMPOUNDS


The e-mobility trend is focusing automotive materials companies on opportunities in and


around the drive battery, but also more widely in new car applications. By Chris Saunders


Compounds for cars of today and tomorrow


The continued rise of electric vehicles (EVs) repre- sents a critical stage in the evolution of the automo- tive industry, with a pivotal aspect for the plastics industry being the development and application of advanced compounds which are essential for reducing weight and enhancing performance while improving safety and overall efficiency. Envalior – the company formed last year


through a merger between the engineering polymers businesses of DSM and Lanxess – has positioned itself at the forefront of the sector. It offers an extensive product portfolio of high-per- formance thermoplastics and advanced composite solutions, many of which were highlighted at the recent international VDI congress Plastics in Automotive Engineering 2024 in Mannheim, Germany. “We see ourselves as a hub of innovation and ideas,” said Matthias Theunissen, Advanced Development Expert Lightweight Technologies at Envalior. “With our wealth of product, application,

and technology expertise, [we] help development partners realise innovations.” At the event Envalior displayed several compo- nents used in power control units (PCUs), including a cooling frame with integrated insulated-gate bipolar transistors (IGBTs) made from Xytron G4024T, a polyphenylene sulphide (PPS) with excellent stability and creep resistance. The same material was used for the high-power transistors in a fully assembled IGBT module with silicon carbide. In addition, the company offers a range of compounds made from halogen-free, flame-retardant polyph- thalamides (PPA) in its ForTii portfolio and polybutyl- ene terephthalates (PBT) in its Pocan portfolio. PBT is a desirable choice up to a current-voltage operating range of around 400 amps/2.5 kV, while PPA and PPS can withstand higher voltages. The company, which says it hopes to become a


‘one-stop shop’ for customers, recently presented a new composite material reinforced with continuous
