Generally speaking, there are microphone waterproof film, speaker waterproof film, and earpiece waterproof film for waterproofing of mobile phones. PTFE waterproof sound-permeable membrane or waterproof breathable membrane and other products from waterproof membrane processing factories such as membranes, and what we are going to introduce below is PTFE waterproof sound-permeable membrane.
With the continuous innovation of virtual reality technology, the popularization of intelligent hardware, and the overall improvement of software functions, our lives have become more and more convenient. The concept of paperless has given birth to smart payment. Traditional bank cards, transportation cards, and cash no longer need to be carried around. All daily consumption behaviors can be realized with a mobile phone. Now that the consumption problem is solved, are there any other inconvenient factors?

Maybe you will say: We add a pair of wireless earphones, but the combination of mobile phone + earphones still cannot free our hands.
PTFE waterproof sound-permeable membrane is made of polytetrafluoroethylene as raw material. It is expanded and stretched to form a microporous film. This film is laminated on various fabrics and substrates using a special process. On the material, it becomes a new filter material. The membrane material has a small pore size, about 0.2-0.5μm, evenly distributed and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve advanced purification and ventilation purposes.
It is a PTFE waterproof sound-permeable membrane manufacturer that specializes in R&D, production and sales. The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability. It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
