Ceramifiable Silicone Applications in EV Battery Packs
Five key protection locations inside an EV battery structure.
From Silicone to Ceramic Protection Layer Under Extreme Heat
BeforeFlexible silicone material
High Temperature ExposureExtreme heat triggers ceramic transformation
AfterRigid ceramic protective structure
When exposed to extreme temperatures, ceramifiable silicone transforms into a stable ceramic barrier that provides thermal insulation, flame resistance, and structural protection.
