1,good anti- acids, alkalis, moisture and organic solvent 2,ideal for filtration of gases mixed with sulfur and moisture
Detailed Product Description
PPS is a special fiber with special trefoiled shape. DWS PPS needle felt filter bag, made of high quality imported fibers, is ideal for filtration of gases mixed with content of sulfur and moisture. Typical applications are industrial/municipal solid waste incinerators and coal-fired boilers.
The characteristics
Chemical resistance: possess good resistance to acids ,alkalis, moisture and organic solvent, but poor resistance to oxidizing agents.Heat-resistance: used under 190°C, instant as high as 220°C, shrinkage under 180°C less than 1%.Good hydroxylation resistance .Low pressure drop.
