Product Introduction
Aluminum silicate refractory fiber is a new type of special lightweight refractory material. It is shaped like cotton and is white and fibrous. The material has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity, good resistance to mechanical vibration, small thermal expansion, and good thermal insulation.
Aluminum silicate refractory fiber and its products and composite materials have been successfully used in metallurgy, electricity, petroleum, chemical industry, machinery, ceramics and other industrial sectors. Cotton, felt, tubes, ropes, plates, bricks, etc. made of aluminum silicate refractory fiber are mostly used in thermal instruments and other equipment.
