Ceramic Fiber Blanket for Electric Boiler

Product description of ceramic fiber blanket

The ceramic fiber blanket is formed by special aluminum silicate ceramic fiber filament through special double-sided needle-punching process. The ceramic fiber blanket does not contain any binding agent. Ceramic fiber blanket can maintain good tensile strength, toughness and fiber structure when used in neutral and oxidizing atmosphere.

Features of ceramic fiber blanket

The ceramic fiber blanket has a regular size and integrates fire resistance, heat insulation and heat preservation. It does not contain any binding agent. It can maintain good tensile strength, toughness and fiber structure when used in neutral and oxidizing atmosphere for a long time.
