Envalior will present its latest materials innovations, focusing on electromobility, lightweighting, sustainability, and safety and comfort, at the Plastics in Automotive Engineering (PIAE) conference organized by the Association of German Engineers (VDI), March 26 and 27 in Mannheim, Germany.
“Our focus is on economical material and technology solutions for batteries, the electric powertrain of electric vehicles, lightweight design, and driving comfort and safety,” explained Dr. Tamim Sidiki, Segment Innovation Manager for Mobility at Envalior. “Another common thread running through our entire presentation is our broad portfolio of bio- and recycling-based materials for a wide range of applications. It saves resources, facilitates the establishment of material cycles and helps our partners in the automotive industry to reduce their CO2 emissions and achieve their sustainability goals, without compromising the technical performance of the components.”
Optimized for thermal shock: PBT mounting frame for mild hybrid vehicles
One of Envalior’s exhibit highlights is a mounting frame made of Pocan B3233XHR. It is used in mild hybrid vehicles in dual-clutch transmissions with an integrated electric motor. The component features a large number of overmolded metal inserts. The PBT compound (polybutylene terephthalate) is particularly effective in this application because of its long-term high elongation at break, hydrolysis resistance and thermal shock stability. These properties ensure that the risk of stress cracking due to frequent and rapid temperature changes is significantly reduced in component areas with overmolded metal components. The dimensionally stable construction material is also less critical in terms of electro corrosion due to its low moisture absorption and exhibits excellent overall electrical properties.
Extremely heat-resistant: PPS for electric vehicle water pump housings
Envalior will also exhibit a water pump for sedans from a global U.S. manufacturer of electric vehicles. The assembly reflects the increasing demand for high-performance thermoplastics in the thermal management of electric power systems. The pump housing is made from Xytron G4024T, which is reinforced with 40% short glass fibers. The polyphenylene sulphide (PPS) compound is highly resistant to ageing in hot air, intrinsically flame-retardant and hydrolytically and chemically durable at high operating temperatures - for example in hot water-glycol mixtures. Its tensile strength, rigidity, high elongation at break and dimensional stability make the compound an ideal fit for precision components that are subjected to high mechanical loads over a long time period. Potential applications for electric vehicles include, among others, water pump housings and impellers as well as components for thermostats or connectors for fluid management.
Lightweight and highly integrated: reinforced polyamide 6 for air spring housings
Also featured at Envalior’s booth will be an exhibit in terms of outstanding driving comfort, safety and fuel-saving aerodynamics - an air spring for a minibus. The housing of the air spring is injection molded from Akulon K-FHG0. It demonstrates the advantages that highly filled, yet easy-flowing polyamide 6 compounds from the Akulon and Durethan product lines have over metals in the construction of such assemblies. They can be used to produce lighter, easily weldable and highly integrated components that are very strong and resistant to pressure and chemicals. Sustainable material variants are also available, which have a CO2 footprint that is around 80% lower than that of comparable polyamide 6 competitor products. They can replace their fossil-based counterparts as a drop-in solution without the need for any additional technical approvals in running production.
Up to 71% share of sustainable raw materials
As an example of a particularly sustainable product series, Envalior will be focusing on Pocan RC X-MB at PIAE. The new PBT compounds are mass-balanced and certified in accordance to the ISCC Plus standard (International Sustainability and Carbon Certification). They combine the use of biomass from waste streams to produce the PBT monomer butanediol (BDO) with mechanically recovered post-consumer PET recyclates and post-industrial recycled glass fibers. In the case of Pocan® T3230 RC X-MB, for example, the sustainable content in the compound reaches 71%. The PBT+PET blend contains 30% recycled glass fibers and produces components with high surface quality and very good dimensional stability. Possible applications in automotive engineering include dimensionally stable housing components with increased mechanical requirements.
Envalior’s presence at PIAE 2025 highlights its commitment to electromobility, lightweighting, sustainability, and safety and comfort. Visit Envalior at Booth 13 to explore these innovations firsthand.
