　　聚碳酸酯（pc）特性：

　　（1）pc是一种非晶体工程材料，具有特别好的抗冲击强度、热稳定性、光泽度、抑制特性、阻燃特性以及抗污染性。

　　（2）pc有很好的机械特性，但流动特性较差，因此这种材料的注塑过程较困难。如果塑件要求有较高的抗冲击性，那么就使用低流动率的pc材料；反之，可以使用高流动率的pc材料，这样可以优化注塑过程。

　　（3）pc塑胶原料它是一种新型的热塑性塑料，透明的度达90%，被誉为是透明金属。它刚硬而具有韧性，具有较高的冲击强度，高度的尺寸稳定性和范围很宽的使用温度、良好的电绝缘性能及耐热性和无毒性，可以通过、挤出成型。

　　（4）pc塑料的热性能优异，可在-100℃-130℃之间长期使用，脆化温度在-100℃以下。

　　（5）虽然聚碳酸酯具有耐开裂和耐药品性较差，高温易水解，与其它树脂的相容性差，润滑性能不好，但是，可以通过加入其它的树脂或者无机填充剂进行改性，从而获得十分优异的性能。

　　pc general introduction:

　　polycarbonate, referred to as pc, is an amorphous thermoplastic.it is a kind of macromolecular compound with carbonate structure inmolecular chain and various materials based on it. according to themolecular structure, they can be divided into aliphatic, alicyclic,aromatic and aliphatic aromatic groups. and bisphenol apolycarbonate is the most important. generally speaking,polycarbonate refers to bisphenol-a polycarbonate and its modifiedvarieties without special instructions.

　　six features of pc:

　　physical and chemical properties: amorphous, tasteless, odorless,nontoxic, tranrent, with certain chemical corrosion resistance

　　mechanical properties; excellent impact strength and dimensionalstability; creep resistance; fatigue strength; friction and wearresistance

　　thermal properties: decomition temperature above 300 ℃, long-termworking temperature up to 120 ℃, embrittlement temperature as lowas - 100 ℃

　　electrical properties: small molecule, high glass transitiontemperature, low water absorption, excellent insulation

　　aging resistance and flame resistance: when heated in air for along time, its performance changes little. pc is combustible.magnesium hydroxide and red phosphorus are added to improve theflame retardancy

　　optical properties: amorphous, pure pc, colorless and tranrent,with good transmittance
