Anyone who knows something about polycarbonate hollow sheet has heard of the term polycarbonate, or PC for short, which is the basic particle that makes up the sheets. Polycarbonate (PC) is polymer that in a molecular chain containing carbonate base, due to the particularity of polycarbonate structure, it has become the fastest growing general engineering plastics in the five engineering plastic.
At present, the Xinhai has successively signed supply cooperation agreement with a number of polycarbonate particle manufacturers, including the international well-known BAYER, SABIC, Mitsubishi chemical, also includes domestic well-known for polycarbonate raw material Luxi chemical and Zhe iron winds, etc. In terms of popularity, bayer raw materials are undoubtedly the most remarkable. From this point, bayer brand is really worthy of the name, the bayer polycarbonate has a certain advantage both from the appearance of the color and the gram per unit, sheets made by it have high density, high quality, life service year is also longer.
For material of the same weight, the price of bayer material is about 30% higher than that of ordinary materials, and the price of sabit is 15-20% higher than that of domestic materials. In terms of the service life or appearance characteristics of the finished PC sheets, bayer materials are indeed higher than imported materials, but the gap is not as high as the price. Over the years, Xinhai compares PC sheet made from bayer polycarbonate and domestic raw materials, there is gap on the hardness, but in the long run the gap on applicability is not particularly big, the key factors are production technology and UV coating.
