Application of PPS(Ryton) Filter Bag:
PPS 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.
Notice:Common brand of PPS include Ryton® and Procon® and belong to Philip Company.
Features of PPS(Ryton) Filter Bag:
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.
