In EV battery systems, Ceramic Silicone and Foam Silicone are used together for protection, sealing, cushioning, insulation and thermal safety — from cell-level compression support to pack-level fire resistance.
Foam Silicone

Foam Silicone in EV Battery Applications
Foam silicone is mainly used in EV batteries for:
- Cell pad cushioning
- Compression support
- Gap filling
- Vibration isolation
- Sealing & dust / water resistance
- Flame-retardant protection
- Thermal insulation assistance
Foam Sheets & Die-Cut Pads
Conventional flame-retardant foam — cell cushioning, gap filling and pack sealing.
Glass Fiber Reinforced Foam
Higher mechanical strength for thermal barrier and structural support layers.
Ceramic Silicone in EV Battery Applications
Ceramic silicone is mainly used in EV batteries for:
- Thermal runaway protection
- Cell-to-cell thermal barriers
- Module side fire protection
- Pack cover fireproof sealing
- Busbar & cable insulation
- High-temperature insulation
- Fire-resistant separation
Ceramifiable Foam
Lightweight ceramic-forming foam for thermal runaway protection inside battery packs.
Solid Compound
Ceramifiable solid silicone for cell-to-cell barriers and fireproof sealing.
Advanced Ceramifiable Silicone Materials for EV Battery Thermal Protection
Flexible silicone materials that transform into ceramic barriers under extreme heat, providing reliable thermal runaway protection for lithium-ion batteries.

Thermal Runaway Protection Challenges
Lithium-ion battery failure can escalate from a single-cell event to pack-level propagation within seconds. Newsil’s material direction is to slow heat transfer, isolate cells and protect surrounding structures before the event spreads.

Battery Failure
Internal short, overcharge or mechanical damage initiates localized heat generation.
Rapid Temperature Rise
Cell temperature accelerates and hot gas jets stress adjacent components.
Thermal Propagation
Heat travels cell-to-cell through conduction, radiation and direct flame exposure.
Safety Risk
Pack-level fire, enclosure damage and system failure become the critical design risk.
Ceramifiable Silicone Technology
Under normal conditions, the material behaves as a flexible silicone foam or rubber. Under extreme heat, ceramic-forming fillers convert the silicone system into a rigid ceramic-like thermal barrier.
