Ceramic Silicon Rubber Fire Resistant Cable

Ceramic Silicon Rubber Fire Resistant Cable 

Application

Ceramics silicon rubber resistant cable is widely used in television stations, hospitals, theaters, commercial buildings, subways.tunnels, railways, airports, railway stations, large public sports, entertainment,supermarkets, hotels, high-rise buildings, military facilities.nuclear power, coal, chemical, pharmaceutical, steel, metallurgy, shipbuilding, civil and so on. Ceramic silicon rubberisa new type ofpolymer composite materials, that can fire at 750℃  x 90min ablative case, not the ashes of burnt powder, can be shaped into ceramicarmor, the formation of a layerof hard protective layer, which is the normal rubber, plastics and other polymer materials can not beachieved, and thus does not short-circuit protection circuit, open circuit.
