People in the auto industry can feel the whole industry is undergoing a new round of unprecedented changes.
Over the past few decades, with the automotive shape and function of the continuous upgrading of various advanced materials have been applied to the new design and manufacturing, polycarbonate (PC) is one of them can not be ignored.
The figure is Koth launched the concept of polycarbonate car K2016 When experts recognize that the use of lightweight composite panels (lightweight composite panels) replacement of high-strength metals, there will still be a high-speed collision, and this phenomenon or will be very common, the use of plastic windows and pillars to solve the problem of blind area becomes a better choice. Because the collision accident of pedestrian and vehicle is usually caused by visual blind area. As the only transparent product in the five engineering plastics, the demand of polycarbonate is increasing rapidly at home and abroad, especially in the automobile market.
At present, the use of polycarbonate (PC) production of panoramic skylight is more and more favored by car buyers.
The United States Sabic-ip Company pointed out that the use of polycarbonate (PC), can revolutionize the design and installation of Windows, and open the window of the mechanical system, coupled with polycarbonate (PC) weight than glass, and in the event of collisions will not hurt people and other advantages, so the application of the prospect is excellent. Webasto, a well-known German auto parts supplier, shares the same view: the boom in panoramic skylight is emerging around the world. In China, for example, as the world's largest car market, one of the three cars produced in China will be equipped with skylights or panoramic skylights. The high heat-resistant polycarbonate can be directly used in the process of producing condenser and reflector parts by vacuum spraying gold plating. In the vacuum spraying, the highest temperature reached 200℃. At this time the product surface does not muster, does not appear the fog spot, does not peel.
Because of the use of polycarbonate, the weight of the front lampshade is less than the inorganic glass 0.5~ 1.4kg. Compared with the equal volume glass material, the net weight of the PC skylight is only 50%. With the constant popularity of the concept of lightweight car, webasto that the development potential of the PC skylight market is enormous. Webasto experts said that although the PC density is only 50% of the glass, but the impact of the material is very outstanding performance. At present, the company has become the Volkswagen Golf A7 model car skylight designated suppliers.
Volkswagen Golf A7 Model PC skylight length 98 cm, wide nearly 1 meters, the total weight of only 1.2 kg. Although polycarbonate has excellent heat resistance, high rigidity, shock resistance, dimensional stability and good transmittance, but because of the UV resistance and chemical resistance of polycarbonate and easy to be scraped, it is necessary to increase the coating on the polycarbonate (PC) surface to ensure that the window's excellent weather resistance and scraping performance. The current Exatec900 system, AS4000, phc587c and as4700f coating systems for the polycarbonate (PC) Windows have been widely recognized (e.g. Smartfortwo, Mercedes SLK skylight coating), These coatings can meet the requirements of the automotive industry and have proved their own long-term stability in actual use.
