Silicone is mainly used for LED packaging, and the global packaging silicone is mainly provided by Shin-Etsu Chemical and Dow Corning. "At present, the domestic silicone market is showing a trend of polarization. Foreign companies have an absolute advantage in the high-end market and the price of domestic silica gel is seized. The low-end market, the CEO of a silicone company in Dongguan told Gao Gong LED reporter.
The world's three major silicone companies dominate the domestic high-end market
At present, the world's three major silicone companies, Dow Corning (Japan), Momentive (USA), Shin-Etsu (Japan) have an absolute advantage in the domestic market, positioning high-end packaging market, Taiwan Tianbao, Changxing, Jieguo, Tianli and other silicone companies in China The end-package market has an important share; domestic silicone companies are basically positioned in the low-end market.
"The three major brands of silicone have their own advantages. Dow Corning's point silica gel has an absolute advantage. At present, more than 80% of high-power packages use Dow Corning's silica gel, which has a 50% market share in mainland China; and Japan's Shin-Etsu silicone positioning higher-end Many high-end packaging companies have designated the use of Shin-Etsu products; Momentive's low-power 3528, 5050 silica gel has an important position in the market," said Shen Wenbin, market agent of Taiwan Tianli Continental Agent Shenzhen Saide Technology Co., Ltd.
When the domestic silica gel enterprises started the price war, the three major silicone companies in the world still win with quality and brand. The market price of Dow Corning silica gel is 5000-6000 yuan/kg, Xinyue is 7000 yuan/kg, and Momentive silica gel is 5,000 yuan/ About jin, while the price of domestic silica gel is maintained at 500-1000 yuan / kg, said Ma Wei, China's agent salesman of Momentive.
It is understood that the three major silicone brand companies in the world have a history of nearly 100 years and have rich experience. Dow Corning was founded in 1943; Moto was in the early days of Toshiba, and was later sold by General Electric and sold to American Apollo Company. The map has been more than 80 years old.
In addition to having a wealth of experience, the technology and quality of the three major silicone companies in the world also have advantages. It is understood that Dow Corning silica gel refractive index is 1.5, Taiwanese enterprises are close to 1.5, domestic silica gel is about 1.4. Shen Wenbin said that foreign silica gel meets the needs of domestic high-end packaging companies. At present, the domestic packaging enterprise market is huge, but the foreign company silica gel has an absolute advantage in China.
Domestic silica gel only meets the needs of the low-end packaging market
At present, there are not many domestic silica gel enterprises, most of them are agents of foreign companies or Taiwanese enterprises. Domestic silicone enterprises are basically not mainstream, and only meet the needs of low-end packaging customers.
"China has a lot of chemical companies, but the scale is small, lack of funds, lack of technology. Domestic silica gel enterprises are mainly in the low-end market, the price is cheap, the quality is barely able to use," said Shen Wenbin.
"At present, domestic silica gel is suitable for a variety of LED packaging products, but the ageing resistance is relatively low, the LED lighting life has a higher product, the choice of imported silica gel is relatively better," a marketing director of a packaging company told Gao Gong LED reporter .
However, some people think that domestic silica gel has reached the international level. Due to the short time of the establishment of domestic silica gel enterprises, there is a lack of recognition and recognition of domestic silica gel in the market. "Domestic silica gel has reached the international market level, the products are also relatively mature, and the heat dissipation and ageing have reached a certain level," said a market player of a certain enterprise in Dongguan.
At present, the LED encapsulation silica gel on the market is divided into high-power LEDs, SMD LEDs, etc. High-power LEDs are further divided into lenses, integrations and die strips, wherein the lens has relatively low requirements on silica gel, and other packages have high requirements on silica gel. “Currently, domestically produced silica gel can be used for the lens type package.â€
The establishment time of domestic silica gel enterprises is about 20-30 years, but with the improvement of technology and the emphasis on the craft level, domestic silica gel can gradually meet the needs of the domestic terminal market. 
The domestic packaging market is huge
[High-tech LED News] According to the statistics of the High-tech LED Industry Research Institute, there are currently about 1,500 LED packaging companies in China, and the number of high-end packaging companies is gradually increasing. However, the high-performance silicone used for packaging is mostly imported. Enterprises have an absolute advantage.
