PPS filter felt is my company use the United States, Japan, the production of polyphenylene sulfide (PPS) fibers, in accordance with the other high-temperature filter felt the production process, processing, filtering material for high temperature filtration material one of the main varieties. PPS needle filter applications in the following situations superior performance.　

　1、 Working temperature 190 ℃, short time working temperature of 232 ℃, melting point 285 ℃, limiting oxygen index 34-35.

      2、 15% or less oxygen in the occasion may be applicable.
　　3、 Fuel sulfur or sulfur oxides from flue gas, now that it is the acid corrosion resistance, chemical resistance, strong fiber.
　　4、 Flue gas with moisture occasions.
　　5、Mining conditions in the temperature of 190-232 ℃, the gas distribution line to do than cleaning up to 5:1 and 6:1 ratio for off-gas cleaning cloth when, PPS filter bags with excellent performance records.
PPS fiber strength to maintain the integrity and inherent chemical resistance, can be in a poor environment to maintain good filter performance, and achieve the ideal life. However, in the filtration of coal boilers, waste incinerators, power plant fly ash dust processing in pulse cleaning dust collector, PPS filter felt is the ideal filter material.
