Ceramic Fiber Blown Bulk

Introduction

Ceramic fiber blown cotton is made by melting high-purity raw materials at high temperature and using blowing method. The product has uniform diameter and white color.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.
