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）--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开发生产工艺介绍
PC的工业合成主要是以双为原料，、和为原料和反应助剂的界面路线。工艺成熟，产品质量高，规模化、连续化生产容易，经济性好。因此，近几年来国内主要的聚碳酸酯生产线都占据了主导地位。年，日本塑料公司成功地研究了非工艺，实现了工业化生产。该工艺主要以双和碳酸二酯为原料，是一种符合环保要求的绿色工艺，已成为未来聚碳酸酯合成工艺的发展方向，预计未来聚碳酸酯生产将逐步占据主导地位
Polycarbonate (PC) has good mechanical properties and good creep resistance, which is better than that of phthalamide and paraformaldehyde. Especially, PC modified by glass fiber has better creep resistance, so it can bear higher load at higher temperature and ensure dimensional stability. The main shortcomings of polycarbonate mechanical properties are easy to produce stress cracking, poor fatigue resistance, high notch sensitivity, no wear resistance and so on. PC has good high and low temperature resistance, good heat resistance at 120 ℃, and hot deformation temperature of 130 ~ 140 ℃. At the same time, it has good cold resistance, brittleness temperature is - 100 ℃, long-term service temperature is - 70 ~ 120 ℃. Moreover, its thermal conductivity and specific heat capacity are not high, its linear expansion coefficient is small, its flame retardancy is good, and it has self extinguishing property. As a weak polar polymer, PC has better electrical insulation although its electrical insulation is not as good as that of polyolefins. Because of its high glass transition temperature and low hygroscopicity, it can maintain good electrical properties under wide temperature and humidity conditions
