Flame-Retardant Foamed Silicone Rubber

Why It Matters for EV and Energy

• Flame retardancy and electrical insulation protect battery modules and electronic enclosures.
• Wide service range from -65C to 200C covers demanding under-hood and outdoor conditions.
• Lightweight cellular structure minimizes added weight in vehicles and energy systems.
• Uniform micropores and low linear shrinkage give dimensionally stable, reliable parts.
• Non-toxic, non-corrosive, non-radioactive and chemically inert for safe handling.

Key Applications

EV and automotive: battery pack perimeter sealing, cell cushioning, thermal management padding, electronic control unit and charging port sealing, seat cushions and headrests. Renewable energy: sealing and protection for solar inverters, wind turbine control systems and charging infrastructure. Aerospace and industry: vibration isolation and insulation for sensitive instrumentation.

Features

• Tunable foaming ratio 2x-7x volume - select density for your application.
• Uniform micropores, low linear shrinkage, reliable compression rebound.
• Flame-retardant, electrically insulating, heat/cold resistant (-65C to 200C).
• Lightweight, no migration; excellent hand feel and softness.
