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与1953年由德国拜耳公司首先研究成功,并于1958年由拜耳公司首先实现了工业化生产, 至今已有四十多年历史。其制造工艺方法有溶液法、醋交换法、界面缩聚法和非法。PC，是一种无定型、无臭、无毒、高度透明的无色或微热塑性工程塑料，具有优良的物理机械性能，尤其是耐冲击性优异，拉伸强度、弯曲强度、压缩强度高; 蠕变性小，尺寸稳定; 具有良好的耐热性和耐低温性，在较宽的温度范围内具有稳定的力学性能，尺寸稳定性，电性能和阻燃性，可在－ 60 ～ 120 ℃下长期使用; 无明显熔点，在220 ～ 230 ℃呈熔融状态，由于分子链刚性大，树脂熔体黏度大; 吸水率小，收缩率小，尺寸精度高，尺寸稳定性好.

（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）。
