As Huawei released a new generation of three-proof smart watches, the innovative application of silicone materials in the field of consumer electronics has attracted attention. The latest device uses a modified silicone rubber case, which uses microphase separation technology to keep the hardness at 60 Shore A while increasing the tear strength to 30kN/m. The screen protection layer innovatively introduces silicone oil-modified polyurethane materials, reducing the friction coefficient to below 0.15 and the hydrophobic angle to 115°, effectively resisting sweat erosion. The polysilazane-silicon dioxide composite coating developed by the company can increase the scratch resistance of the device by 5 times and extend the service life to more than 3 years. Market data shows that the global demand for smart wearable silicone materials will increase by 45% year-on-year in 2023, of which the penetration rate of medical-grade silicone rubber in health monitoring equipment has reached 32%. Experts predict that with the development of flexible electronic technology, silicone protective materials with self-healing functions will become the core competitiveness of the next generation of wearable devices.
