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耐老化性和耐燃性 聚碳酸酯的耐热老化性能也相当好，若将其薄膜放置空气中长时间加热，其性能变化很小。聚碳酸酯是可燃的，火焰呈淡、冒黑烟；氧指数仅25%，离开火焰自熄。一般加入卤化物、、氧化、和等改性提高阻燃性。
Due to the non crystallinity of polycarbonate, the packing between molecules is not compact enough. The organic solvents of aromatic hydrocarbon and chlorinated hydrocarbon can make it swell or dissolve, which is easy to cause solvent cracking. The alkali resistance is poor.
LEXAN™ PC
沙伯基础创新塑料 - 聚碳酸酯 塑胶原料
LEXAN是什么材料：LEXAN 是SBAIC-IP沙伯基础创新塑料(原美国GE)生产的PC 聚碳酸酯商品名
PC mechanical properties: polycarbonate has excellent mechanical properties, especially its impact strength and dimensional stability. It is difficult to maintain high mechanical strength in a wide temperature range. Its disadvantages are poor fatigue strength and wear resistance, and easy to produce stress cracking.
尽管PC具有许多优能，然而由于PC分子链的高刚性和大的空间阻位使其具有较高的熔体粘度，因此加工困难，易开裂，耐溶剂性和耐磨损性较差，因此对PC改性研究成为PC应用研究重要的课题，目前聚合物合金化成为PC改性重要途径，国外已有大量性能优良PC合金投入市场，随着PC合金材料的研究不断进展，PC的应用范围不断扩大，
PC开发前景的应用领域，宽波透光的光学器械，作为一种透明性能良好的工程塑料，PC作为光盘基材在全球大量使用， 不仅可以制备CD、VCD、DVD光盘，还可以适用于高密度记录光盘的基材， PC片材特别适宜于制作眼镜镜片，在PC分子链中引入硅氧基团，可以提高其硬度及耐擦伤性。PC作为高折射率塑料，用于制作耐高温光学纤维的芯材
