Globally First Intumescent Fire-retardant Long-glass filled PP for Large Electric Vehicle Battery Pack Enclosures
Category: Mechanical/Materials
Developers: SABIC
Product Description:The automotive industry is going through a tectonic shift towards electric vehicles. In doing the same, the value chain is facing some major challenges, which can potentially impede the speed of EV adoption. They include safety concerns resulting from thermal runway events in an electrified powertrain, lightweighting needs with the relatively heavy and expensive battery pack made of multi-piece metal components and meeting other critical requirements to enhance efficiency and performance. While thermoplastic solutions can address many of these challenges, extensive development, prototyping and validation timelines at a battery pack level often slow down adoption of thermoplastic fire retardant materials and solutions using the same for EV battery packs. The current innovation relates to development of fire-retardant intumescent products that not only enhance performance, weight saving and part integration, but also address the major challenge — long validation timelines at pack level — thus offering a solution for faster adoption of EV and the global warming challenge. Fire retardant (FR) STAMAX Resins are glass fiber-reinforced, intumescent thermoplastic materials for manufacturing large electric vehicle (EV) battery packs that are lighter (10% compared to metal-intensive solutions) and safer, and up to 40% less costly solution than metal-intensive solution propelling sustainable transportation. These materials deliver the right property profiles to meet critical requirements for large EV battery pack applications. In addition to stiffness, strength and impact resistance over a wide temperature range, the materials offer dimensional stability, low coefficient of thermal expansion and good creep resistance. With PP as the matrix material, it offers excellent water and chemical resistance and electrical insulation properties. These glass fiber reinforced grades offer thermal barrier properties to help delay or contain thermal runaway propagation. It also demonstrates flame-retardant behavior and intumescent properties for fire safety.
