Ultra High Strength Fireproof Composite Silicone Rubber Strip Excellent Flexibility
Battery Interface Ceramic Substrates Fireproof composite ultra-high-strength fireproof material refractory fabric
Fireproof composite silicone rubber is an ultra-high-strength fireproof material with unique refractory silicone rubber and refractory fabric. It is designed to protect fire-sensitive parts or structures. Due to the superior fire resistance of the soft silicone rubber, it not only resists flame ablation at least 1000°C but also avoids the spread of flame to other areas. These unique features enable the material to address safety and design issues in electric vehicles, rail trains, and industrial machinery.
