Ceramic low smoke halogen-free polyolefin refractory
Ceramic low smoke halogen-free polyolefin refractory is a new type of high performance refractory material developed for fire-resistant wire and cable. It takes polyolefin resin as the base material, adds high-efficiency porcelain filler, flame retardant and other functional additives, and is made by mixing, plasticizing and granulating. Compared with the traditional low smoke halogen-free material, its advantages are: in the flame burning or high temperature conditions can generate a hard ceramic shell, the shell does not melt, does not drip, can resist water spray, and has a very good heat insulation effect, can ensure the smooth flow of power and information control in the case of fire, for personnel escape and fire rescue for valuable time.
