Lower Heat Resistant K Wool Ceramic Blanket Fireproof 1260 For
Boiler Insulation
Production Description:
ceramic fiber blanket is composed of long,flexible,interwoven
fibers manufactured by the “blown”and the “spun”process yielding a
strong,lightweight 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.
Applications:
Ceramic Fiber Blanket is made of high purity Alumino-Silicate (and
Zirconia) fibrous wool.
♦ Refractory back-up installation
♦ Direct exposure to heat as furnace hot face lining
♦ Expansion joint seal
♦ Fire protection
♦ General high temperature insulation
