Silicone rubber coated fiberglass sleeve is manufactured by weaving fiberglass into a tubular structure and then coating it with high-temperature-resistant silicone rubber, followed by vulcanization. This process creates a durable, flexible sleeve with excellent flame retardancy, thermal insulation, electrical resistance, and corrosion resistance. It is widely used for protecting cables, hoses, and hydraulic fittings in extreme heat environments such as steel mills, foundries, glass factories, and firefighting equipment.
