An ultra-lightweight, fire-resistant material has been introduced by Trelleborg’s applied technologies operation for use in electric vehicle (EV) battery protection and increased fire-risk applications. 

Soteria FRV is the second material in the company’s Soteria range of protection materials. Weighing just 1.2 kg/m2 and extremely flexible, Soteria FRV can be shaped to fit areas of any size; it can also be draped or wrapped around difficult profiles. When combined with Soteria FR1500 panels, it creates lightweight protection for EV battery boxes and enclosures. It can also serve as a stand-alone option for increased fire-risk applications.

Soteria FRV is flame-resistant to 1100°C for up to 90 minutes, with no burn through or expansion during a fire, according to Trelleborg. No ongoing maintenance is required once it has been installed and it is easy to transport.

Soteria FRV material will be on display in the Product Innovation Zone at the inaugural International Composites Summit in London on Sept. 8 and 9. The summit is a joint exhibition and open forum focused on the worldwide supply chain for composites. More information about the event is available here.
