    This product is a new type material of fire-resistant flame retardant silicone rubber. After vulcanizated, it keeps high elasticity of rubber at room temperature, and under the high temperature it forms hard ceramic layer. The ceramic layer has a certain strength and be capable of impact resistance. It keeps  parts well running when fire breaks out. It is particularly applicable to fire resistant cables and refractory sealing strips.
