Ceramic Fiber Bulk

Introduction

Hengrui ceramic fiber bulk is produced by melting the very pure raw materials in high temperature, take use of spun or blowing method with characteristics of stable chemical performance, resistance to the erosion of most chemicals. The physical property like refractory and insulation keep same when meet with oil,water or steam.

Ceramic fiber blanket/ felt/ board/ paper/ cloth/ rope and other ceramic fiber products can be produced by bulk through further processing. Hengrui ceramic fiber bulk is a kind of insulating materials which has these characteristics, such as light-weight, anti-oxidation, low thermal conductivity, softness, anti-corrosion, low heat capacity, sound insulation and so on.
