Silicone rubber coated fiberglass cloth for flexible fabric bellows is a high temperature industrial fabric woven from high quality E-glass filament yarn, and then coated with a specially formulated wet (liquid) silicone rubber on one side or both sides. This fabric provides good properties of flexibility, durability, water and oil proof, abrasion resistance, and excellent resistance for general chemicals. It's primarily used for high-temperature insulation, fire protection, and environmental sealing.It is heavily used for welding blankets, thermal insulation blankets(jackets covers pads), expansion joints, protective covers, conveyor belts, and waterproof outdoor gear.This durable material provides resistance to chemicals, UV light, and heat up to 260°C
