CS-70 series is a new type of ceramic silicone rubber solid material that can be porcelain at high temperature. The series has all the characteristics of silicone rubber at room temperature, and can be transformed into a "ceramicized" hard shell with the advantages of insulation, heat insulation, fire insulation and buffering at high temperature, so as to play a good role in fire retardant and flame retardant. The material can be compounded with glass fibers for integrated production, making it an ideal choice for fireproof and flame-retardant materials in railway traffic, industrial environments and electronic equipment.
