ceramic fiber blanket

Characteristic:

Ceramic fiber blanket made from common, high pure, zirconic, chromic aluminium silicate fibre, after the process of needling, thermoforming, crossbar cutting, rolling up ,etc. which is through double-sided needling operation by using spun technology. Needling blanket in different size and thickness provide users a wide range of material selection to gain the best heat insulation structure and energy saving effect.

Low heat strong capacity, Low thermal conductivity

Excellent thermal stability and shock resistance, resist devitrification at high temperature

Excellent tearing resistant

Excellent insulating performance, fire prevention and sound absorption

Double—side needling operation produces tough, resilient and strong blankets, which resist tearing both before and after heating.

Easy cutting and installation

Application

All kinds of industrial kiln linings(hot surface and back lining)

Furnace body expansion joint, furnace door,top cap seals

High building fire proof and heat insulation

Thermal resistance component of auto industry with

High temperature filter media

Insulation for field stress relieving of welds
