Ceramic Fiber Blanket
Brief description
Leadsun 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 C to 1430 C Ceramic fiber blanket has the heat resistance of a hard refractory with five times better insulation value.
