Ceramic fiber (also known as aluminum silicate fiber) is a fibrous material manufactured from raw materials including kaolin, alumina and silica, through melting in an electric resistance furnace followed by blowing or spinning processes. Compared with rock wool, ceramic fiber features a higher temperature resistance rating, with a long-term service temperature of up to 1000℃–1200℃ and above, and a lower thermal conductivity of less than 0.03 W/(m·K).
In fire-resistant coatings, ceramic fiber provides superior thermal insulation barriers and excellent thermal shock resistance. It retains its fibrous form under high-temperature flame impact without pulverization or shrinkage. Therefore, ceramic fiber fire-resistant coatings are mainly used in harsh working conditions such as petrochemical plants, high-temperature equipment pipelines, nuclear power facilities, and special steel structures requiring ultra-thin intumescent fire resistance.
Ultra-high temperature resistance: Class A1 non-combustible. Classification temperature ranges from 1260℃ to 1400℃. Provides long-lasting and reliable fire protection.
Excellent thermal insulation: Extremely low thermal conductivity effectively blocks heat transfer and eliminates thermal bridge effects.
Superior thermal shock resistance: Protective coatings do not crack under rapid cooling at 900℃. Impact resistance can be up to 14 times higher than unprotected materials.

Founded in 2002, the company is a specialized manufacturer and engineering service provider for thermal insulation, sound absorption, and fireproof spraying materials. The facility covers 15,000 square meters for manufacturing, technical R&D, and office use, with an annual production capacity of 60,000 tons.



Over the years, the group has been committed to the R&D of fireproof and sound-absorbing construction technologies. The sprayed mineral wool products feature a fine texture, low slag ball content, and high fiber strength. Our micro-particle products can replace asbestos in high-quality brake pads and gaskets, significantly improving wear and temperature resistance.
