Alumina silicate fiber felt is categorized into two types based on different applications: rolled felt and flat felt. The product boasts excellent high-temperature resistance, with a thermal conductivity 30% lower than that of other insulating materials under the same conditions. It is lightweight, elastic, and stable, offering good sound absorption and insulation properties, as well as stable chemical characteristics, all of which ensure its wide application. Additionally, the product has superior electrical insulation properties, making it suitable as a high-frequency insulating material.
Alumina silicate fiber boards are formed by adding a certain proportion of binder during the blowing of alumina silicate wool to create alumina silicate felt. Subsequently, they are heat-treated and shaped in a curing room with hot air penetration. The boards are then automatically cut using a computer control console, resulting in shaped alumina silicate dry boards. These products are widely used in the power, shipbuilding, construction, fire-resistant door, automotive, and train manufacturing industries for fire and heat insulation. They are also an excellent choice for lining heating equipment and high-temperature reaction equipment in the chemical industry. Additionally, they can be used as furnace lining, furnace door, and roof sealant materials.
Our company produces high-quality alumina silicate fiber cotton with excellent chemical and thermal stability. The product is made from hard clay clinker as raw material, with production processes including resistance or electric arc furnace melting, blowing into fibers, etc. In applications, it can serve as a filling and insulating layer for equipment, raw material for vacuum-formed products, and as a base for fiber castable and coating materials. Our alumina silicate fiber cotton is free of binders and corrosive substances, ensuring reliable quality and worthy of the trust of consumers.
