It is understood that the commonly used LED packaging materials are mainly transparent materials such as epoxy, polyurethane, and silicone. Among them, the silicone material is the material with the best performance. Mainly in: good heat resistance and UV resistance, and good compatibility with the chip. Therefore, with the increase of the luminous efficiency of the high-power LED, its application in the field of lighting is gradually expanding, and the amount of high-power LED packaging materials will increase accordingly.
In this regard, the industry pointed out that liquid silicone rubber products have moderate viscosity, good mechanical properties, high transparency, good resistance to aging, is an ideal material for high-power LED packaging. With the rapid development of the LED industry, silicone products for high-power LED packaging will usher in a period of rapid development. Among them, liquid silicone rubber products are undoubtedly the most concerned.
It can be seen that industrial mass production of domestic liquid silicone rubber products not only helps domestic products get rid of the dependence on imports, but also effectively promotes the development of the entire LED industry, and has positive significance for the improvement of the entire industry.
