PPS+PTFE needle punched filter is the use of imported 50% PPS+50% PTFE fiber needled and that of PPS+PTFE fiber to the excellent acid and alkali resistance and oxidation resistance and wear resistance,resistance to fold advantage, making normal temperature of 200°C composite mat, short time of up to 220°C for in thermal power, waste incineration, coal- fired boilers, etc. with high sulfur content of flue gas filtration.
