(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 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
