Generally speaking, it is difficult for some high-tech products such as phones, watches, and mobile phones to improve both water-repellent performance and audio performance at the same time. The key lies in how to strike a balance between the two. It ensures that water cannot enter while ensuring its audio performance. You can usewaterproof sound-permeable membranefor phone watches. In addition to ensuring that the quality of the sound is not affected, the membrane also has excellent water-repellent properties. .
Phone Waterproof and sound-permeable membrane for watchesIt is a semi-finished product of the film formed by extruding rods and strips of polytetrafluoroethylene and calendering. It is stretched at a temperature below the melting point and heat-set to obtain a porous product. The porosity of the PTFE hydrophobic breathable membrane can reach more than 85%, allowing the air to flow smoothly. The membrane pore size is 0.1-1μm, and the size of the pore size can be adjusted according to needs. The pore size is small, and the protection level can reach IPX7 or above. Used in the protection of electronic products, it can prevent electronic products from being damaged in humid or watery environments.
It also has certain applications in food packaging, anti-haze screens, air filtration, etc. Through continuous investment in R&D costs and technical strength, the products have passed authoritative testing and certification. We always take it as our mission to contribute to human health and social environmental protection and continue to work hard.
