With the rapid growth of urban population, the construction of high-rise buildings, large supermarkets, subways, tunnel transportation and other facilities continues to increase. People are paying more and more attention to fire safety, and flame retardant and refractory materials are playing an increasingly important role in many fields of national production and life. Due to the high bond energy of the Si-O bond in silicone rubber, the silicone rubber itself has good thermal stability. In addition, when burned under high temperature flames, the Si-O bond will transform into a continuous, antioxidant, and insulating network of silica SiO2 ashes covering the surface, effectively preventing further erosion. In addition, the smoke generated during the combustion process of silicone rubber matrix is mainly CO2 and H2O generated by the combustion of side chain groups, which do not produce toxic gases and do not pollute the environment. Therefore, silicone rubber has unique chemical stability, high and low temperature resistance, weather resistance and insulation. At the same time, it has low smoke and non-toxic, low combustion heat value, and slow flame propagation speed during combustion, which makes it widely used in aerospace, electronic and electrical, power transmission and other fields.

Ceramic silicone rubber is a new type of fireproof and flame-retardant material, which has the elasticity and electrical insulation of ordinary silicone rubber at room temperature. However, it can transform into a hard ceramic body under open fire or high temperature conditions. The use of silicone rubber to prepare ceramic refractory silicon materials has unique advantages in terms of process and raw material selection, as well as high temperature resistance and mechanical properties of ceramic products. At present, ceramicized silicone rubber is mainly used as a fireproof material in the wire and cable industry. When a fire occurs, ceramicized silicone rubber can form a hard ceramic protective layer, which plays a role in isolating flames and preventing fire. It can keep the internal copper wires of wires and cables from melting within 30 minutes, providing valuable time for personnel evacuation and rescue in case of fire.

It is mainly used in fireproof cable, ceramic fireproof composite cloth, flexible Mineral-insulated copper-clad cable fireproof filling, new energy vehicle battery pack fireproof insulation gasket, new energy vehicle battery pack fireproof cover, etc.
