[Aluminium] Aluminium has always been considered to be a more economical, thermally conductive metal, although its thermal conductivity ranks high on the entire metal family. However, it's cheap and good, so that people will see it with another eye. The thermal conductivity of gold, silver, and copper in metals is between 330 and 360, and the thermal conductivity of aluminum is around 200, both of which are good conductors of heat. However, gold, silver and copper in the market are all very expensive metals. Only aluminum is the better choice for people to compromise. In the past, everyone used aluminum as a heat lamp cup because of its economic benefits. But nowadays people pay more and more attention to the environment and pay more and more attention to non-renewable resources. Although aluminum is good, it is, after all, a non-renewable resource, and it is sometimes necessary to use electroplating for the lamp cups. The pollution to the environment is even more serious. And aluminum recycling costs are quite high, so many companies can not afford it. Aluminum has matured in this LED market and is known to everyone. However, in the face of the current emphasis on sustainable development, aluminum will eventually be withdrawn from this stage of history. Innovation is the theme of the times. Those former glories have become history and can only be missed but not practical.
The emergence of thermally conductive plastics broke the LED market dominated by aluminum. The head of Philips lighting industry, it is famous for leading the trend of lighting, but also dared to dominate the lighting industry. Thermally conductive plastics is Philips' innovative spirit that empowers him to develop DSM. Today's Philips, today's DSM, is the leader in the lighting industry because of the innovation in thermal plastics. At present, DSM's thermal conductive plastic PA46TC551 made by Philips has a thermal conductivity of 2W/MK between boards and 14W/MK inside the board. This is a considerable breakthrough, plastic instead of aluminum, which if you do not want to think before. Now it has been slowly realized, and when the heat-conducting plastic meets the thickness of less than or equal to 5mm, and the thermal conductivity is above 12W/MK, it can achieve the same thermal conductivity as aluminum. At present, DSM's material is still relatively expensive, and it can only be consumed by state-owned or large companies in China. Therefore, many small and medium-sized enterprises are deterred.
For the thermal plastic market, high prices, foreign technology monopoly. Bao Lima dares to be the first person to dare to innovate and dare to challenge international chemical companies. In R&D and production, there are breakthroughs in place of DuPont, Teijin, BASF, and Toray. Not only do they have the same performance as theirs, but they also surpass them, such as PET raw material for hair straighteners, and they have the advantage of price. Today, Bao Lima has created a historical glory. In early 2011, Baolima succeeded in developing thermal plastics successfully and became a domestically-developed manufacturer of thermal plastics and put into production lines. The thermal conductivity coefficient is 2W/MK between boards, and the board is 18W/MK. The substrate used is PPS. The cost of heat-conducting plastics has been greatly reduced, and it is a domestic company that has a balance between time and place. The price of DSM thermal conductive plastic PA46TC551 on the market is generally 170-270 yuan / KG, because it contains smuggling prices, so it floats. However, Bao Lima's thermal plastic is ethical blood, and it is the Chinese who independently develop blood. Our price is currently only about one third of DSM. 100 yuan / KG tax price, in fact, the cost of everyone can figure it out, PPS currently have more than 80 yuan / KG, plus some other expensive additives, let alone say. Bao Lima is not anything else, just to break the monopoly of foreign markets, just to set aside its own brand in the chemical industry.
