What is flame-retardant silicone foam for battery packs

Flame retardant silicone foam is a closed cell foam material specifically designed to achieve high performance sealing. It has demonstrated UL94 class flame resistance in tests, maintaining its rated temperature at 205°C (401°F) and maintaining its performance at low temperatures of -55°C (-67°F). In addition, the foam maintains water resistance at a compression rate of 20%, compressive deformation resistance of less than 10%, and high tensile strength.

In the new energy automobile industry, silicone foam cotton is used to seal the battery box to provide good shock absorption and sealing effect. These foam usually come in colors such as gray, black, or red. The material of flame retardant silicone foam is silicone rubber board, which has good flame retardant and shock absorption performance.

In addition, silicone foam is also used in the support pad of the liquid cooling plate of the power battery pack, which shows that it is more and more widely used in the electric vehicle industry.
