PPS is a high temperature fiber, with continuous working temperature 160°C, max working temperature 200 °C. Its chemical resistance is excellent except for oxidising agents such as Oxygen and No2. It has very good acid resistance and this, together with a good thermal resistance has led to wide acceptance in combustion processes.

Polyester is the most cost-effective and most widely used filter media for dust collection. It is strong , abrasion resistant. It can work up to 150 ℃ and continuous working temperature 130 ℃, has good resistance to common acids, solvents.
Acrylic, named polyacrylonitrile , which is used as raw material to make felt by acupuncture ,and via the refused special treatment to get temperature hydrolysis-resistant filter needle felt, and finally enhanced vertical and horizontal strength by taking Acrylic machine weaving cloth as the coax ,which mainly used in
polypropylene needle felt is the most lowtemperature resistant material with moderate cost,it is also shows excellent resistance tohydrolysis and acid-resistant , it is mainly used in the condition of which thetemperature is not high and has large amount of moisture.
Mines and limestone powder, cement raw meal, millingmachines iron, casting, sintering, iron and steel industry; aluminatransportation electrolytic aluminium , colored metal smelt smoke; and woodprocessing ,food processing ,pharmaceutical and industries of the dust collection.
Compared with Fiberglass material, FMS abrasion resistance, folding resistance and peel strength are improved obviously. And in the aspect of shape stability , it also better than other chemical material . meanwhile ,its price is less than that of the nomex membrane material ,which is popular among users.
