Encapsulating silicone rubber for led

Silicone rubber is currently the most important selection of high-power LED packaging materials. Silicone rubber for led is the floorboard of the organic silicone materials for LED optoelectronic industry. Weaker anti-ozone ability for epoxy resin makes the colloid yellowing, affecting the light effect. While, encapsulating silicone rubber for led has excellent properties such as resistance to atmospheric aging and ultraviolet aging, and the epoxy resin has been replaced by silicone rubber for led in the application of high-end products. The famous manufacturer of LED silicone rubber has HongYe, BlueStar, DowCorning, Smooth-on, ShinEtsu, and Wacker.   Silicone rubber for led is mainly used for encapsulating of high-power LED, including filling, mold tripod, integrated encapsulation type, etc., as well as SMD package and the white glue mixed phosphor used.     The most commonly encapsulating material is epoxy resins and silicone rubber. In actual use, we found that the comprehensive properties of silicone rubber are obviously better of epoxy resins, and encapsulating silicone is more widely used. The most prominent performance of silicone rubber for led is mainly reflected in the following aspects:   1. Heat resistance properties Encapsulating silicone for led product has an excellent thermal stability, and the chemical bonds of molecules do not broken and decompose at high temperature (or radiation exposure). High-power led silicone rubber not only resistant to high temperature, but also low temperature, which is available in a very wide temperature range. The physical and mechanical properties or chemical properties of silicone rubber for led have very small change along with the change of temperature.   2. Weather resistance The main chain of led silicone rubber products is -Si-O-, unparalleled key exists, and therefore, it is not easy to be broken down by ultraviolet and ozone. Silicone rubber for led has better thermal stability and resistance to radiation and weathering capability than other polymer materials. The service life of encapsulating silicone rubber can be up to several decades in the natural environment.   3. Electrical insulation properties Encapsulating silicone for led product has good electrical insulating properties, the dielectric loss, resistance, voltage, arc resistance, corona, volume resistivity and surface resistivity of which have come out in front in insulating materials. The temperature and frequency have a minimal effect on their electrical performance. Therefore, as a stable electrically insulating material, silicone rubber for led is also widely used in electronics, electrical industries. Besides, led encapsulating silicone has excellent water repellency, which has high reliability when used in wet conditions.   Shenzhen Hong Ye Jie Technology Co., Ltd has earned the status of a navigator in silicone rubber industry. 95% of our encapsulating silicone rubber for led has been widely exported to more than 90 countries and regions. The stable product quality, careful process control, professional and meticulous services have a great vogue in fields such as American, Europe, and Asia.
