The microporous structure of interlaced fibers has good air permeability, and the porosity reaches 85 % or more can ensure smooth circulation of air. The pore size is 0.1μm-1μm, which can effectively block water droplets. At the same time, the film has good rigidity, moderate density and small sound insulation loss.
Currentlyptfe waterproof and sound-permeable membrane can be widely used in mobile phone handsets, headphones, speakers, speakers, children’s phone watches, lighting equipment, etc. In terms of field, the product is waterproof and breathable. Balance internal pressure and reduce condensation, extending product life. Interested parties can enter the store for consultation and purchase!
