Covestro’s new flame-retardant encapsulation polyurethane foam technology strengthens the company’s position as a trusted materials partner in the evolving EV value chain.
Covestro has unveiled its next-generation flame-retardant encapsulation polyurethane foam technology, addressing one of the most critical challenges in electric vehicle (EV) adoption worldwide: battery safety. This innovation strengthens Covestro’s position as a trusted materials partner in the evolving EV value chain.
As the world’s largest EV market, China is taking a decisive step with the introduction of the groundbreaking national standard GB 38031-2025: Electric Vehicles Traction Battery Safety Requirements. Effective from July 2026, this regulation demands that batteries must not catch fire or explode—even in the event of a thermal runaway. These stringent requirements are expected to shape global safety standards in the years ahead.
Breakthrough flame-retardant encapsulation foam technology
Covestro’s newly launched Baysafe® BEF flame-retardant encapsulation foam series is designed to minimize thermal propagation between battery cells—tackling a key safety concern that has challenged consumer trust in EVs. The lightweight foam delivers superior flame-retardant performance by effectively inhibiting fire spread, significantly enhancing battery safety in applications ranging from EVs to portable energy storage systems.
“This innovation represents a significant step toward enabling sustainable mobility through enhanced safety,” said Akhil Singhania, Global Head of PU Specialties in Covestro’s Tailored Urethanes Business Entity. “By launching our advanced flame-retardant technology, Covestro reaffirms its commitment to innovation and strengthens our product portfolio to meet the evolving needs of the EV industry.”
This development comes at a pivotal time as EV adoption accelerates globally and safety regulations become more demanding. As Chinese automotive companies expand internationally, Covestro’s innovative materials solutions illustrate how technological advancements support successful cross-border market growth.
