Covestro has introduced Baysafe® BEF, a new flame-retardant polyurethane foam designed to enhance battery safety in EVs and energy storage systems. The foam minimises thermal propagation between cells, reducing fire risk.

The launch aligns with China’s GB 38031-2025 battery regulation, effective from July 2026, which sets stringent safety standards. "This innovation represents a significant step toward enabling sustainable mobility through enhanced safety," said Akhil Singhania, Global Head of PU Specialties at Covestro.

The foam's lightweight structure and fire resistance meet the needs of global EV manufacturers and portable power system developers. Covestro’s broader portfolio also includes shock-absorbing materials and battery covers.

This development strengthens Covestro’s position in the EV supply chain as regulations tighten worldwide.
