High-Density Silicone Foam for Shock Protection in Electric Vehicle

Product Description

Product Description

Silicone Foam

Silicone foam, also known as foamed silicone, is a porous, low-density, compressible polymer elastomer made through a high-temperature and high-pressure process. Its raw materials include silicone rubber raw rubber, fillers, vulcanization accelerators and foaming agents. After uniform mixing, it forms a material that combines the high elasticity of silicone rubber with the sound insulation and shock absorption properties of foam materials. Silicone foam is a porous, low-density material that combines the elasticity of silicone rubber with the sound insulation and shock absorption properties of foam materials.

Product Highlights

* Strong waterproof and sealing performance: Above IPX8 level
* High fire resistance and flame retardancy: UL94 V-0 level
* Lightweight and highly elastic, providing long-term     buffering and shock absorption capabilities
* Low thermal conductivity, excellent heat insulation performance
* Excellent collapse resistance at high temperatures
* Small and uniformly fine foam cell size, with ultra-stable performance

Properties and Applications of Silicone Foam in Batteries

Waterproof and Weather Resistance
Silicone foam is renowned for its excellent shrinkage recovery property, which plays a key role in the charging and discharging processes of batteries, effectively preventing deformation caused by the thermal expansion and contraction of battery cells. Its outstanding durability, low shrinkage, excellent impact absorption, and UL 94 V0 flame retardancy make it widely used in buffer heat insulation of new energy battery cells and frame sealing. In addition, silicone also has good waterproof performance, further enhancing its applicability in the field of new energy vehicles.

It has excellent waterproof performance and low shrinkage, effectively protecting the battery from environmental impacts. The performance of silicone foam remains stable in various temperature environments, and its waterproof and sealing properties ensure no water seepage during outdoor use, providing additional protection. During long-term use, the shrinkage damage of silicone foam is very small, and it has the function of inhibiting shrinkage deformation. The UL 94 V0 flame retardancy effectively prevents potential risks of batteries caused by thermal effects.
