PPS Filter Bags

PPS Filter bags are often used in coal-fired boilers, but also for waste incinerator, coke oven, kiln, chemical drying process of flue gas purification process. In carbon black, powder collection, pneumatic conveying, chemical, cement plants, power plants and so on.

Dewdon provide a wide range of PPS Filter Media, which is useful in various industrial applications. PPS is a high temperature thermoplastic fiber with excellent resistance to hydrolysis and so is a good complement to aramid fibers, being frequently used where their susceptibility to moisture is a problem.

Product Features

The acid and alkali resistance is Excellent. Meanwhile, PPS fiber does not burn, neither does it support burning. The temperature resistance is up to 200℃ (392℉). The resistance to oxidation is poor. So the working environment requires the oxygen content less than 14%(Vol.), and the oxynitride content is less than 600mg/Nm³. The higher oxygen contents the lower working temperature.
