"Only reached the international level in the key technical parameters on the domestic market, silica gel is." Zhongshan Fuli Chemical Co., Ltd. (hereinafter referred to as "Fuli chemical") general manager of LED said Mr. li.
It is understood, the domestic market share of the vast majority of glue is still dominated by foreign enterprises. In recent years, the domestic market gradually rise of glue. Judging from the current situation, through the introduction of high quality silica raw material and adding filler reinforcement way can develop debut Corelle alternative products, and in the price is only half of Dow corning. The current domestic manufacturers to seize the market price of glue more, but with the 2012 external market downturn and the integration of the industry intensifies, simply by reducing the price of it is very difficult to achieve a major breakthrough in the LED glue market, "quality" war broke out.
Quality control and technical innovation
"High quality glue must grab from fountainhead." Mr. Li said. It is understood, the raw material of glue industry is heavily dependent on imports of the problems are quite common. Such as the production of high refractive index and molding silicone raw materials -- silicone or silicone resin, can be home production enterprises and foreign enterprises rarely, and only the sale of finished products, virtually increased domestic silica production cost. It is understood, the domestic market Dow Corning silicone, almost occupy 90% of the market share. But the domestic silica gel technology in recent years has made a great breakthrough, there have been a few enterprises to the development and production of similar DOW CORNING high refractive index with powder rubber substitute products. "The current customer attaches great importance to product quality." According to He Daxian introduction, Hengda new material of high refractive index distribution powder glue in product performance basically consistent with Dow Corning, in some aspects such as slightly better, according to a well-known packaging enterprise test: do 1W light source, all materials are the same (including chip, support, insulation rubber, phosphor, etc.), the process is the same, using different rubber powder, 350MA current lighting test, kraft? K-5509M-2 flux than DOW CORNING high 3%, and only half price Dow corning.
