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 weak polar polymer. Although the electrical insulation of PC is not as good as that of polyolefins, it still has good electrical insulation. Because of its high glass transition temperature and low moisture absorption, it can maintain good electrical properties under a wide range of temperature and humidity conditions. Especially, its dielectric constant and dielectric loss are close to constant in the range of 10 ~ 130 ℃, so it is suitable for manufacturing capacitors. PC polycarbonate has certain chemical resistance. It is resistant to water, organic acid, dilute inorganic acid, oxidant, salt, oil, fatty hydrocarbon and alcohol at room temperature. However, it is eroded by alkali, amine, ketone, ester and aromatic hydrocarbon, and dissolved in trimethyl methane, dichloroethane, cresol and other solvents. Long term immersion in boiling water will also occur hydrolysis. In some chemical reagents, such as carbon tetrachloride, polycarbonate may cause stress cracking
PC是分子主链中含有碳酸酯基的聚合物统称为聚碳酸酯，根据醋基结构可分为脂肪族、芳香族、脂肪族一芳香族等多种类型。目前商业化聚碳酸醋的基本结构为芳香族代。由于代是一种综合性能优良的非晶型热塑性树脂, 具有优异的电绝缘性、延伸性、尺寸稳定性及耐化学腐蚀性, 较高的耐热性和耐寒性还具有自熄、易增强、阻燃、无毒、卫生、能着色等优点，聚碳酸醋是增长速度快的通用工程塑料，目前聚碳酸醋的工业化装置基本上都是采用界面缩聚法工艺, 主要工艺是将双与溶液配制成双盐, 同时加人, 然后送人反应器内, 加人, 通进行化反应,反应完后将反应液送到缩聚反应器内, 加人和溶液, 进行缩聚反应.

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
