Alumina silicate fiber felt can be divided into two types according to different uses: alumina silicate fiber roll felt and alumina silicate fiber flat felt. The product boasts excellent high-temperature resistance, with a heat conductivity rate 30% lower than that of other insulation materials under the same conditions. It is lightweight, elastic, stable, and has superior sound absorption and insulation properties, as well as stable chemical performance, all of which ensure its wide application. Additionally, the product has excellent electrical insulation properties, making it a suitable choice for high-frequency insulation materials.


Alumina silicate fiber boards are produced by adding a certain proportion of binder during the blowing of alumina silicate wool to form alumina silicate felt, which is then subjected to heat-air penetration curing in a curing room. The boards are automatically cut by a computer-controlled console to become shaped alumina silicate boards. The product has a wide range of applications, including excellent fireproof and insulation properties for the electric power, shipbuilding, construction, fire-resistant door, automotive, and train manufacturing industries. It is also a good choice for the wall lining of heating equipment and high-temperature reaction equipment in the chemical industry. Additionally, it can be used as furnace lining, furnace door, and roof sealing material.


Our company produces alumina silicate fiber棉 with excellent chemical and thermal stability. The product uses hard clay clinker as the raw material and the production process includes melting in resistance or arc furnaces and blowing into fibers. In applications, it can be used as a filling and insulation material for equipment, raw material for vacuum-formed products, and as the base for fiber casting and coating materials. Our alumina silicate fiber棉 is free of binders and corrosive substances, offering reliable quality and is a trustworthy choice for consumers.
