PTFE Needle Felt General Type
PTFE needle felt general type is the main product for producing PTFE filter bags. First of all, 100% virgin PTFE scrim was made by membrane tear PTFE filament yarn. Then PTFE staple fibers were processed by needling process.
PTFE needle felt general type is the main product for producing PTFE filter bags. First of all, 100% virgin PTFE scrim was made by membrane tear PTFE filament yarn. Then PTFE staple fibers were processed by needling process. In the later stage, the process of impregnation or laminating can be done according to the requirements of customers. PTFE needle felt is suitable for harsh environment with high corrosive conditions and high temperature. It has been in the fields of waste incineration, medical waste incineration, thermal power generation and chemical gas filtration.
