PPS needle punched filter felt is used in pulse bag filters in coal-fired power plant boiler.
Product Introduction: PPS needle punched filter felt is used in pulse bag filters in coal-fired power plant boiler. The full name is PolyPhenylene Sulfide (PPS). PPS felt usually deals with the gas from low-sulfur coal. Adopting the PPS fiber and high temperature felt process method; we produce high quality of PPS felt.
