（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）。
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
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 Basic Description:
PC can be divided into aliphatic, alicyclic, aromatic and aliphatic aromatic groups. As one of the five engineering plastics, polycarbonate mainly refers to bisphenol a polycarbonate. PC is a kind of thermoplastic engineering plastics with excellent comprehensive properties. It can be used to manufacture parts such as machinery, automobile and precision instrument. It can also be used in electronic components and electric tool parts. However, the processing and molding requirements of PC are high, and it has no self-lubricating property, so it is not suitable for manufacturing products with metal inserts. Due to its non-toxic, good chemical resistance and excellent food hygiene performance, PC can be widely used in daily life. In particular, its tranrency is superior to other engineering plastics, so it is widely used in aviation glass, lamps, safety glass, office equipment, laser disc and other fields. It can be said that in all areas of the national economy, PC has been widely used, and is still expanding.
