Acrylic Needle Felt

Detail

Acrylic needle felt

Normally in filtration field, acrylic refers to homopolymer acrylic which is essentially made from 100% of acrylonitrile. Homopolymer acrylic needle felt and acrylic filter bags for industrial filtration. This kind of acrylic needle felt is with good ability of acid and alkali resistance, anti-oxidation, hydrolysis resistance.


The major feature of acrylic fiber are its excellent resistance to hydrolysis. Its common cost compares with the high performance fibers and reasonably high temperature resistance. It is widely used in metallurgy, chemical, building material, electric power station, mechanism industry, petroleum, medicine, printing and dyeing, food and beverage, and other industries to filter gas and recycle material.
