Alumina silicate fiber felt can be divided into two types according to different uses: rolled felt and flat felt. The product boasts excellent high-temperature resistance, with a thermal conductivity 30% lower than that of other insulation materials under the same conditions. It is lightweight, elastic, and stable, offering good sound absorption and insulation properties, as well as stable chemical properties, 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 fiberboard is produced by adding a certain proportion of binder to the alumina silicate cotton during the blowing process, forming alumina silicate felt. It then undergoes heat curing with hot air through a curing room, and is automatically cut by a computer-controlled console to become shaped alumina silicate dry boards. The product has a wide range of applications, offering excellent fireproof and insulating properties for the power, shipbuilding, construction, fire-resistant door, automotive, and train manufacturing industries. It is also a great choice for the wall linings of heating equipment and high-temperature reaction equipment in the chemical industry. Additionally, it can be used as furnace lining, door, and roof sealant materials.


Our company produces alumino-silicate fiber cotton with excellent chemical and thermal stability. The product uses hard clay clinker as raw material and the production process includes melting in resistance or electric arc furnaces and blowing into fibers. In applications, it can serve as equipment filling and interlayer, raw material for vacuum-formed products, and as raw material for fiber casting and coating materials. Our alumino-silicate fiber cotton does not contain binders or corrosive substances, ensuring reliable quality and is worthy of the trust and confidence of consumers.
