1260/1350/1430C Ceramic fiber blanket

Ceramic fiber blanket is made of special ceramic long-fiber that is produced by melting very pure raw materials in double surface needing process.

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.
