ePTFE membrane special process

The ePTFE membrane is made of polytetrafluoroethylene microporous membrane laminated with ordinary fabric through a special process. The fabric integrates the excellent waterproof and moisture-permeable properties of the ePTFE membrane, so that sweat vapor can quickly penetrate the fabric, and the human body will not feel stuffy, so it is the top waterproof and breathable material at this stage.

Fabric water repellent treatment → Corona discharge → Rotary screen gluing → PTFE film unwinding, corona treatment, laminating → drying and hot pressing compound → PTFE film surface treatment → (gluing → compound lining →) trimming → rolling → Inspection → packaging → finished product. The water-repellent finishing of the fabric can be carried out in a single-sided liquid-feeding manner after compounding as needed. The use of corona treatment is very effective for improving the bonding strength of the composite.
