The unique structure of silicone, both inorganic materials and organic materials, with low surface tension, viscosity-temperature coefficient is small and other basic properties, and has high and low temperature resistance, electrical insulation, oxidation resistance stability, weather resistance, flame resistance, water aversion, corrosion resistance, non-toxic, tasteless and physiological inertia and other excellent characteristics. Widely used in aerospace, electronic and electrical, construction, transportation, chemical, textile, food, light industry, medical and other industries. From the perspective of function, silicone is mainly used in sealing, bonding, lubrication, surface activity, demoulding, defoaming, foam suppression, waterproof, moisture-proof, inert filling, etc. With the continuous growth of the types of organic silicon materials, the application field is constantly widened, forming a unique important product system in the field of chemical new materials, many varieties are irreplaceable and essential to other chemicals.


LED packaging silicone is a new type of application with the development of the LED industry, and there are very obvious differences with the common traditional silicone materials in the past. LED packaging silicone requires products with light and color characteristics, electrical properties, mechanical properties, high heat resistance characteristics and interface matching characteristics of a variety of materials. These matching materials include metal and non-metal materials of different materials. All of these features need to be considered not only for immediate features, but also for long-term aging performance levels. From the point of view of material demand, LED packaging silica gel undoubtedly belongs to the ranks of the most difficult silicone materials. At the same time, because the WHOLE LED industry is still in a highly competitive stage, in order to design differentiated products in the market, LED packaging silica gel with different characteristics and requirements has appeared, and the replacement of mainstream products is also very fast, which requires continuous increase in R&D investment. The above two aspects will accelerate the rapid reshuffle of LED encapsulated silica gel supply chain, and in the future, it may enter the model of strong combination of the whole value chain.
