Description

Description of Ceramic Fiber Blanket:


With a regular size, Ceramic fiber blanket integrates fire resistance, heat insulation and heat preservation. It can still maintain good tensile strength, toughness and fiber structure when used in a neutral and oxidizing atmosphere for a long time. It has the characteristics of low heat capacity, low thermal conductivity, excellent chemical stability, excellent thermal stability, and no powdering under working temperature.
