What is a PTFE Membrane?

Polytetrafluoroethylene membrane(PTFE membrane) is a synthetic material that expands to form a microporous film (also called Teflon film/membrane) and can be laminated to functional fabrics. The microporous PTFE has waterproof, windproof, and heat-resistant properties which are used to produce waterproof breather membrane, and is ideal for firefighter clothing, sports, leisure clothing, and military equipment material.

As the expanded PTFE membrane manufacturer, the SunGod PTFE film (polytetrafluoroethylene film), which is produced by us, is combined with a cross-linked polyurethane coating and penetrates into the PTFE structure. This improves the durability of the porous film. It means that after repeated washing, wearing, and using, SunGod PTFE membrane will stay on its task.

SunGod is the worldwide first and only expanded polytetrafluoroethylene membrane manufacturer licensed to use Chemours TeflonTM fluoroplastic logo.

As one of the most professional PTFE membrane manufacturers from China, SunGod has top-quality waterproof and breathable membranes for sale. If you want to know our PTFE membrane price or other product information such as eptfe film, micro porous film and hydrophobic PTFE membrane, please contact us or leave a message through our website.

Micro Porous Membrane Technology

SunGod PTFE membrane is built with 9 billion nanoscopic pores per square inches that work instantly to vent out sweat vapor which generates inside of your gear when you perform. The micro porous film is dry and comfortable in the widest range of conditions, which results in a critical difference to traditional non-porous film solutions. The microporous hydrophobic direct vent dry system has your sweat vapor vent out without a multi-step process and free of wet feeling inside the skin.
