PPS needle punched filter is the use of imported 100% PPS fiber needled and that of PPS fiber to the excellent acid and alkali resistance and oxidation resistance and wear resistance,resistance to fold advantage, making normal temperature of 180°C composite mat, short time of up to 210°C for in thermal power, waste incineration, coal- fired boilers, etc. with high sulfur content of flue gas filtration.
