Envalior has unveiled a new line of thermoplastic formulations designed to address the heat management challenges inherent in high-voltage electric vehicle architectures. These materials include flame-retardant compounds and high-performance electrolyte additives that improve battery safety and durability.
Why it matters
As automotive manufacturers shift toward more powerful high-voltage systems, they require specialized insulation that balances flame retardancy with mechanical ductility. These materials help address the significant heat generated during vehicle operation and charging cycles.
New materials like Stanyl SN-PURE reduce cell heat generation by 33%, while the ForTii F11 polyamide achieves V-0 flame-retardant certification at a thickness of 0.2mm.
The players
