Product Description

Laurel ceramic fiber blanket is composed of long, flexible, interwoven fibers manufactured by the “blown” and the “spun” 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.
