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

P84 (polymide) dust collector filter media displays excellent stability under dry high heat temperatures, has great filtration properties, and performs well even under elevated levels of moisture content.

▶Fiber/Core Material：P84（Polyimide powder）
▶Pros：Excellent stability in applications with high dry heat temperatures, mineral acids, and alkaline.
▶Cons：Must oversize bag for shrinkage that can occur in temperatures above 450 Degrees F.
▶Applications：Waste-to-Energy，Coal Fired Boilers，Incinerators

Nomex is characterized by good heat resistance, fspinnability , wear resistancelammability and non-melting. Its fiber-oxygen index is 29 percent. It also has good dimensional stability. Compared with glass fiber, its wear resistance and folding resistance are unparalleled. The Nomex Filter Bag it is the first choice of bag filter for high temperature filtration.
▶Fiber/Core Material：NOMEX(Meta Aramide）
▶Pros：Nomex material dust filter bag has strong points of high-temperature resistance, can be up to 220 degrees, good abrasion resistance, anti-adhesion.
▶Nomex dust filter bags are easily hydrolyzed, easily rotted by acid vapors. It is therefore only suitable for certain applications.
▶Applications：Boiler，Hot asphalt concrete，Cement industry，Steel factory , and more.

PTFE fiber is a macromolecular linear structure, so it has strong temperature resistance, abrasion resistance, corrosion resistance, and chemical resistance. It is widely used in various harsh flue gas filtration environments such as steel, electricity, and garbage incineration.

▶Fiber/Core Material：PTFE（Polytetrafluoroethene）
▶Pros：Excellent weather resistance, stable performance under high temperature, low temperature, high humidity and other environments; low pressure drop performance can be maintained under high flow environment, and the filtration efficiency does not change.
▶Cons：The price of PTFE filter bags is quite expensive. In addition, the bonding wear resistance is poor. The bag frame must have 20 bars or more to support the filter bag.
▶Applications：Multi-fuel boiler, Waste incinerator
