1. Specification
Polytetrafluoroethylene is made from the monomer tetrafluoroethylene by free radical vinyl polymerization. PTFE is perhaps the most inert, chemically resistant, and temperature resistant polymer used in industrial filtration. Its characterizes are as follows:
100% PTFE bag is mainly used in chemical industry, waste incineration, high temperature resistant liquid filtration, keeps good chemical stability in the complex condition.
Finish Treatment: Singeing, Calendering, Heat Setting, Anti-static, Water&Oil Repellent, PTFE Membrane, PTFE Impregnation and so on
Bag Size: it is up to the CPO and installation and customized
Bag Head: seal cuff / groove snap / felt strip, bead cuff/ steel strip, etc can be chosen
Bag Body: Sewing or Hot sealing
Bag Bottom: Single or double bottom, with reinforcement or without reinforcement
