The mask film produced by ptfe mask film manufacturer is made of ptfe resin as raw material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching. Its pore size, thickness, and porosity can all be Adjust as required while stretching.
PTFE mask filter membrane is a polymer waterproof material.
From a production point of view, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. From a quality point of view, it also has functional characteristics that other waterproof materials do not have.
The porosity of the film can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
?ptfe mask membrane manufacturer has a full set of domestic advanced production equipment and adopts advanced production technology. The products have passed ISO9001 quality management system certification. The testing standards strictly follow the EU standard EN1822. The membrane products are tested using the MPPS method.
