Optimizing thermal management systems for EVs with advanced materials

Automakers are increasingly investing in electric vehicles (EVs) to meet stringent CO2 emission regulations set by governments, as well as consumer demand for greener vehicles. As automotive brands bring more EVs to market, they need to address the safety issues related to electric engine batteries.

In EVs, thermal management systems (TMS) are critical to keeping battery packs within the optimal temperature range to improve engine efficiency and service lifetimes as the EV operates. Additionally, TMS continue running when the EV is being charged to prevent battery pack thermal runaway – which is especially critical for fast EV charging. This requires manufacturers to ensure the thermoplastic components in TMS are tested to withstand more than 10,000 hours of exposure to coolant chemicals.

  • PPS - Xytron™

    Xytron is a high performance plastics compound based on linear polyphenylene sulfide. Xytron offers extreme chemical resistance, dimensional stability, and is intrinsically flame retardant.

  • PA4T PPA - ForTii®

    ForTii has a unique PPA's technology with high amide density. The ForTii platform includes polymers that are the highest crystalline, highest melting point and highest glass transition temperature amongst all PPA.

  • PA410 - EcoPaXX®

    EcoPaXX is a high-performance aliphatic, biobased polyamide that uniquely balances the benefits of typical short and long chain polyamides, such as low moisture uptake and high mechanical performance.
