1260C 1430C Ceramic Fiber Blanket Board

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.
