Detail:

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

 

Features:

High mechanical characteristics 
Excellent resistance to hydrolysis 
Optimal heat stability both in dry and wet conditions 
Optimal resistance to chemical agents 
Extraordinary resistance to light, weathering, mildew and bacteria
