With the continuous development of science and technology, various polymer materials are constantly being used in various products, especially in consumer electronics products. Vinyl fluorideWaterproof sound-permeable membrane is one of them.
Expanded polytetrafluoroethylene membrane (ePTFE) is a new type of polymer material with micron or sub-micron porous The three-dimensional network microstructure is made of polytetrafluoroethylene (PTFE) resin through special processing methods such as stretching and turning. While maintaining the excellent chemical properties of PTFE, it changes the structure, shape, thickness, and surface geometry of the material. , and then matched with auxiliary materials with different characteristics to achieve different functions and uses.
Waterproof sound-permeable membraneNot only has the excellent comprehensive properties of PTFE, such as high chemical stability, high and low temperature resistance, corrosion resistance, It has excellent properties such as climate, high lubrication, good non-adhesion, electrical insulation, and good biocompatibility. It also has new properties such as porosity, breathability, hydrophobicity, flexibility, etc. that PTFE does not have. It is a A very good waterproof, dustproof, breathable and sound-permeable material.
Waterproof sound-permeable membrane is used in the gaps and slots of consumer electronics products to achieve waterproof and dustproof levels, and can also make the sound Maintain signal-to-noise ratio and low distortion after passing through the waterproof membrane. In addition, the film has good rigidity, moderate density, and small sound insulation loss. It can also be widely used in waterproof digital cameras, walkie-talkies, smart watches, handheld ultrasound machines, handheld navigators, smart water cups, children’s smart early education machines, speakers, earpieces, speakers, etc. on the product.
Waterproof sound-permeable membrane has a high waterproof and dustproof grade that can reach IP68, which can well protect sensitive electronic components and extension products. It has a long service life and reduces the probability of fault maintenance. The product has a wide range of applications. Interested parties can enter the store for consultation and purchase!
