Thermal Shock Resistance Refractory Ceramic Fiber Blanket For Fire Protection
Quick Detail:
♦ Needled blanket
♦ Non-combustible
♦ Low density and low thermal conductivity
♦ Shorter heat up and cool down time
♦ Resilience and resistance to thermal shock
♦ Flexible and easy to cut or install
♦ Consist of acoustic properties
♦ Contain no organic binder
♦ Asbestos free
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℃ to 1430℃ 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
