[Text / Zhu Chunwei] In recent years, mainland China's domestic packaging silicone manufacturers have launched low-cost high-end silicone, trying to enter the higher-profit high-profile packaging silicone market.
The statistics of the High-tech LED Industry Research Institute (GLII) show that as of the end of the third quarter of this year, the average unit price of high-end silicone in mainland China has dropped from 3,500 yuan/kg in 2012 to 2,000 yuan/kg, a drop of more than 43%. As the price of high-end silicones continues to drop, more packaging companies will use high-end, high-profile silicones instead of low-profile silicones.
At the same time, some domestic packaging manufacturers have also begun to try to use domestic high-end silicone to replace similar products with relatively high prices in Japan and the United States.
Guangdong Hengda New Material Technology Co., Ltd. is one of the representatives of domestic high-end silica gel. Heda Xian, the company's LED project manager, said that with the further reduction in the profit of LED packaging, the market share of domestic glue is still in a gradual increase. Especially under the premise of the same quality, the price of domestic glue is much lower than that of imported glue.
At the beginning of this year, Evergrande New Materials officially released a new LED silicone product with higher cost performance, involving two series of four products: LED package silicone and LED application lamps.
K-5204k is a high thermal conductivity thermal conductive adhesive with a thermal conductivity of up to 1.6. It is mainly developed for LED application lamps. It is a reinforced neutral silicone elastic rubber. It has excellent high and low temperature resistance after curing. The thermal conductivity and bonding performance will not fall off after long-term use; at the same time, the product has no corrosive effect on metals such as aluminum and copper and PC, PPA and other plastics, and can be used for LED bulbs, fluorescent tubes, spotlights, ceiling lamps, etc. Bonding heat conduction.
Evergrande New Materials began to enter the LED industry in 2007. Its main products include LED packaging adhesives, LED sealing adhesives, LED potting adhesives and LED thermal adhesives. The product has excellent yellowing resistance, no barrier layer with phosphor, strong colloid adhesion, high temperature resistance and high transparency. Its "Kraft" brand has successfully entered the market in the past two years and has a good reputation.
