Silicones for safer
EV batteries

Extend time available for evacuation

Prevent thermal propagation

Limit thermal spread

In case of a battery thermal runaway, every second is important.

WACKER’s silicones can contribute to containing propagation. Our battery researchers have prepared test results and product recommendations for you.

See how:

Potting or coating with silicones can help to limit thermal spread
Silicones can protect battery cells and prevent thermal propagation
A silicone resin fiber laminate can extend passenger evacuation time and increase battery safety: It remains intact even in the hot particle stream produced by thermal runaway
