Flame-retardant thermoplastics for electric vehicle battery packs

Electric vehicles are a rapidly growing area for automakers. SABIC is helping automakers make the transition by helping them develop next-generation electric vehicle battery packs with our reliable thermoplastic solutions. Another concern for the electric vehicle industry is the series of issues and challenges surrounding thermal runaway. And here, too, SABIC can help. In terms of electric vehicle battery packs and related applications, we have deep expertise in flame-retardant polymers and have accumulated rich experience. In addition, we also provide a wide range of flame-retardant materials that can help automakers meet battery safety requirements and regulations.

 

SABIC thermoplastics for electric vehicle battery packs and related components offer many advantages. Our materials are inherently lightweight, meaning manufacturers can significantly reduce weight, thereby improving performance and achieving increased range. Corrosion-resistant properties make it more durable and last longer. In addition to being lightweight, low-cost thermoforming and injection molding manufacturing processes provide further cost savings. In addition, SABIC plastics have excellent thermal and electrical insulation properties and have superior thermal stability compared to other metals. Fluorine rubber sealing ring manufacturer

 

Application of SABIC flame retardant polymers in electric vehicle battery packs

As shown, our thermoplastics can meet the requirements of a range of electric vehicle electrical components.

 



 

For a variety of applications, we offer a range of high-performance flame retardant (FR) materials, including our SABIC® polypropylene compounds (PPc) and STAMAXTM long glass fiber (LGF) PP resins, as well as engineering thermoplastics (ETP) (For example, LEXANTM polycarbonate (PC) resin and a variety of polybutylene terephthalate (PBT), polyester fiber (PET) and PC mixtures) and other series of products. Using these materials in the design of a variety of EV battery pack components, including one of our halogen-free intumescent flame retardant systems, enables comprehensive, higher-performance battery solutions.

Understand fire safety requirements

Understanding the fire safety requirements for electric vehicle battery packs is important, especially considering extreme overheating conditions at high battery loads, as well as thermal runaway conditions.

 

Relevant international and industry standards include fire tests and occupant protection tests in the event of thermal runaway reactions. If flame retardant thermoplastics are used, these materials must pass specific overheating tests based on typical automotive standards and OEM requirements in the event of battery thermal runaway, as shown below.
