Dongguan Jinghong plastic is located in Zhangmutou town, Dongguan City, Guangdong Province, China. It is a professional plastic raw material trader engaged in various projects. We do not produce raw materials, but only serve as the most professional supplier. Since its establishment, the company has actively advocated the business philosophy of "integrity as life, word-of-mouth is more important than Mount Tai", and wholeheartedly provides the best quality service for the majority of new and old customers. We have established a good reputation among peers and customers based on the development principle of "your satisfaction is the most important thing for me". We have been actively exploring the market through the Pearl River Delta region, and have established a long-term friendly cooperative relationship with large-scale plastic manufacturers at home and abroad.
PC is a kind of polymer with carbonate group in the main chain, which is called polycarbonate. According to the structure of acetic acid group, PC can be divided into aliphatic, aromatic, aliphatic aromatic and so on. At present, the basic structure of commercial polycarbonate vinegar is aromatic. As a kind of amorphous thermoplastic resin with excellent comprehensive properties, it has excellent electrical insulation, extensibility, dimensional stability and chemical corrosion resistance, Polycarbonate vinegar is a kind of general engineering plastics with fast growth rate. At present, the industrial plant of polycarbonate vinegar basically adopts the process of interfacial polycondensation. The main process is to prepare bisphenol sodium salt from bisphenol and caustic soda solution, add human , and then send it into the reactor, After the reaction, the reaction liquid is sent to the polycondensation reactor, and the solution of caustic soda is added to carry out polycondensation reaction
（PC）--工程塑料的简介
工程塑料一般是指可以作为结构材料承受机械应力，能在较宽的温度范围和较为苛刻的化学及物理环境中使用的塑料材料。
工程塑料可分为通用工程塑料和特种工程塑料两大类。
通用工程塑料通常是指已大规模工业化生产的、应用范围较广的5种塑料，
即：
聚酰胺（尼龙，PA）
聚碳酸酯（聚碳，PC）
聚（POM）
聚酯（主要是PBT，PET）
聚醚（PPO，或变性PPE）。
The production of PC resin is mainly concentrated in the United States, Western Europe and Japan. The production capacity of these three regions accounts for about 90% of the world's total production capacity. At present, the development of polycarbonate industry in the world presents two major characteristics. One is that production tends to be more centralized and monopolized. The production capacity of Bayer company, Ge chemical company, Dow Chemical Company and 13 bendi company account for about 80% of the world's total production capacity. Among them, Ge electric gas, Bayer, Dow Chemical and Japan's Diren company respectively account for the world's total production capacity in 2000 35%, 31%, 9% and 9% of production capacity. These companies control the world's polycarbonate production technology and dominate the world polycarbonate market. Second, Asia is develo rapidly. In recent years, with the gradual recovery of Asian economy, especially the sustained and rapid development of China's economy, the demand for engineering plastics is becoming stronger and stronger. World famous polycarbonate manufacturers have also come to Asia to invest and build factories.
PC是一种中等耐磨材料（但比金属好得多）。与尼龙、聚、氯化聚醚、聚等相比，但优于ABS、聚砜、有机玻璃等。通过添加聚、玻璃纤维等填料，可以提高PC的耐磨性，降低摩擦系数和磨损损失，提高PV值。PC具有良好的耐热性和耐寒性。可在-100～130℃范围内长期使用。具有较高的载荷变形温度（130～140℃），受载荷影响较小。脆性温度在-100℃以下，即使在-180℃也不会像玻璃一样破碎。PC无明显熔点，在220～230℃熔融。由于高分子链的高刚性，其熔融粘度远高于其他热塑性塑料
