With the rapid growth of urban population, the construction of high-rise buildings, large supermarkets, subways, tunnel transportation, etc. has continued to increase, and people are paying more and more attention to fire safety. Flame retardant and refractory materials play an increasingly important role in many areas of national production and life. Due to the high bond energy of Si-O bonds in silicone rubber, silicone rubber itself has good thermal stability. In addition, when burning under high-temperature flames, Si-O bonds will be transformed into continuous, anti-oxidation, insulating network-like silicon dioxide SiO2 ash covering the surface, thereby effectively preventing further ablation.In addition, the smoke generated by the silicone rubber matrix during combustion is mainly CO2 and H2O generated by the combustion of side chain groups, and no toxic gases are generated, which will 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 produces less smoke and is non-toxic, has a low combustion calorific value, and a slow flame propagation speed, making it widely used in aerospace, electronic appliances, power transmission and other fields.



Ceramic silicone rubber is a new type of fire-retardant material. It has the elasticity and electrical insulation of ordinary silicone rubber at room temperature, but it can be transformed into a hard ceramic body under open flame 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 in the high temperature resistance and mechanical properties of ceramic products. At present, ceramic silicone rubber is mainly used as a fireproof material in the wire and cable industry. When a fire occurs, ceramic silicone rubber can form a hard ceramic protective layer to isolate the flame and prevent fire. It can keep the internal copper wire of the wire and cable from melting within 30 minutes, which wins precious time for the evacuation and rescue of personnel in the event of a fire.

It is mainly used in fireproof cables, ceramic fireproof composite cloths, flexible mineral insulated cable fireproof fillings, new energy vehicle battery pack fireproof insulation gaskets, new energy vehicle battery pack fireproof covers, etc.
