High Temperature Insulation 25 50mm Fire Resistant Fireproof Insulation Refractory Ceramic Fiber Blanket High Pure
Laurel ceramic fiber blanket is composed of long, flexible, interwoven fibers manufactured by the “spun” or “blow” process yielding a strong, light weight yet durable blanket for applications in a temperature range from 1100℃ to 1430℃Ceramic fiber blanket has the heat resistance of a hard refractory with five times better insulation value.
