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）。

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
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
