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.
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.
Beyond encapsulation foams, Covestro offers a wide range of polyurethane-based solutions for EV
batteries, including battery covers and shock-absorbing materials. The new Baysafe® BEF technology
further strengthens Covestro’s position in the fast-growing new energy sector, supporting safer,
more reliable electric mobility applications such as new energy vehicles and e-bikes, as well as
portable battery generators.
