Performance and characteristics:
PPS Series Chemical Fiber Filter Material
Made of PPS fiber (polyphenylene sulfide) through three-dimensional acupuncture, it can be used for a long time below 190°C. With excellent chemical stability and strength integrity retention, it performs exceptionally well in flue gas environments with high sulfur content, suitable for coal-fired boilers, electric power, and garbage incineration.
PTFE Series Chemical Fiber Filter Material
Crafted from PTFE fiber (polytetrafluoroethylene) via three-dimensional acupuncture, it features a macromolecular linear structure, offering extremely strong stability, wear resistance, chemical stability, and outstanding temperature resistance. It is widely applied in various harsh flue gas filtration environments such as steel, electric power, and garbage incineration.
