IP68 membrane, that is, waterproof, breathable and sound-permeable membrane, is widely used in electronic products such as smart phones, smart wearables, handheld terminals, Bluetooth headsets, and speakers that require waterproofing.
At present, the waterproof sound-permeable membrane used in water depths below 30 meters can be realized by conventional processing methods. However, when the water depth is below 50 meters, not only the precision of the membrane thickness is high, but also the overall uniformity and stability of the membrane are required. , which cannot be achieved by conventional processing methods, which has become a technical problem.
"The feature of this membrane is that it can achieve the highest level of water resistance and sound transmission, and at the same time it is waterproof, with almost no sound loss." SDSR's CTO Dr. Rong, in his hand, is a roll of IP68 PTFE Nano Membrane products , The diaphragms with a length and width of about 1.8 mm are evenly and neatly arranged.
After a year and a half of technical research, IP68 PTFE Nano Membrane was successfully developed in the second half of 2018 and has now been commercialized. Now it has been supplied in batches to several leading electronic manufacturing enterprises in China. This product not only solves the long-term dependence on foreign countries for the core materials of electronic product enterprises, but also greatly improves the competitiveness of China's electronic industry in the international market.
About SDSR
The company is dedicated to R&D and manufacturing of high performance PTFE microporous membrane, PTFE fiber and PTFE engineering plastics.
PTFE Microporous Membrane
The surface of the polytetrafluoroethylene material has a spider web-like microporous structure, and has very complicated changes in the three-dimensional structure such as network connection, hole inserting, and hole bending, so it has an excellent surface filtering function. The nano mask produced by this material has the characteristics of high barrier efficiency, long service life, thin and breathable.
