Fiberglass composite needle felt is a filter material made by mixing fiberglass and high temperature resistant functional fibers (such as P84, PTFE, etc.).
The fiberglass composite needle-punched filter felt series products have the characteristics of high temperature resistance, high strength, acid and alkali corrosion resistance, wear resistance, and folding resistance. Anti-static and other characteristics; and a series of products suitable for different temperature ranges such as 150~200℃, 200~250℃, 250~300℃.
Compared with fiberglass filter material, fiberglass composite filter material has significantly improved wear resistance, folding resistance and peel strength, and can bear high filtration load. The filtration speed can reach more than 1.0m/min, and the running resistance is low. Compared with synthetic chemical fiber high temperature resistant filter material, it overcomes the disadvantages of high elongation, large deformation, low temperature resistance and poor corrosion resistance of chemical fiber filter material; dimensional stability and strength are better, and the price is lower than other high temperature resistant chemical fibers , has been widely used in steel, non-ferrous smelting, chemical industry, carbon black, building materials, electric power and other industries.
