Features

Application:
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
Characteristic:
► 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
