PTFE composite materials come in two forms: one is polytetrafluoroethylene fiber coated on a base cloth made of other filter materials (polyphenylene sulfide fiber, P84 polyimide fiber, glass fiber, etc.). The other is that both the coating and the base fabric are made of polytetrafluoroethylene fiber and processed into needle felt.
100% PTFE fiber filter bags provide better performance.
Despite its superior performance, the high price of polytetrafluoroethylene fiber is an obstacle that restricts its wide-scale promotion.
