Description of Ceramic Fiber Blanket:
The ceramic fiber blanket is of standard size and integrates fire prevention, heat insulation and heat preservation. It can maintain good tensile strength, toughness and fiber structure even after long-term use in neutral and oxidizing atmospheres. It features low heat capacity, low thermal conductivity, excellent chemical stability, excellent thermal stability, and no powdering at working temperatures.
