PPS filter bag
PPS dust filter bag PPS needle felt is a filter material made of PPS fiber (polyphenylene sulfide) through three-dimensional needle punching. It can be used for a long time at a temperature of about 160°C. PPS fiber is also called polyphenylene sulfide fiber. Due to its special molecular structure, it has good chemical stability and strength integrity retention characteristics.
▶Fiber/Core Material：PPS（polyphenylene sulfide）
▶Pros：Excellent resistance to acids and alkaline
▶Cons：Sensitive bag to cage fit.
▶Applications：Asphalt Plants，Cement Mills，Incinerators
PPS also otherwise known by the proprietary name Ryton© or Procon©, is a filter bag media that is commonly used in dust collection applications where excellent resistance to acids and alkaline is required. Carbon black, chemicals, and cement applications are a few industries that frequently utilize PPS filter bags.

| Note: In the PPS composition, there is 30% sulfur, so the possibility of the material being oxidized at high temperature will reduce the life of the bag, so it is necessary to consider reducing the temperature or reducing the oxygen content to increase the life of the bag. Screening. | |||||
APPLICATION OF PPS DUST FILTER BAG
▶The factory operates in the production of cement, functional foods, pharmaceuticals,…
▶PPS filter bags are also used in filtration systems at coal-fired thermal power plants, ash factories, and fly dust filters in large dust filtration systems.
▶Commonly used in coal-fired boilers, garbage or ash incinerators, and static cleaning.
