Polyacrylonitrile fibers have good resistance for the organic solvents, oxidant, inorganic and organic acids and hydrolysis.

Acrylic can be widely used inwaste incinerators, bitumen, coal mills, and power plantsfor the dust collection at the low temperature, chemical corrosion and wet working occasions.

Acrylic needled felt can receive different functional treatments, such as :water and oil proof, PTFE dipping , coating, laminatingand so on.
