 在溫度低于125℃時，顯示出對有機溶劑，氧化劑，無機及有機酸具有良好的抵抗力。丙烯腈均聚本不會水解，因此在低溫而有化學腐蝕及潮濕的場合用來取代聚酯。按照工況條件的不同要求，可以對亞克力針刺氈做各種功能性處理，如拒水防油，PTFE浸漬，涂層，覆膜等。
Acrylic needle felt show good resistance to organic solvents, oxidant, inorganic  and organic acid when temperature lower than 125 ℃。 Because of this feature acrylic usually use instead of polyester in the low temperature and chemical etching environment. Functional finishing treatment can be made according to special working conditions.
