PC薄膜片材可以说是一种无定型以及无臭、无毒和高度透明的无色或者是微黄色的热塑性工程塑料，PC薄膜的片材应用得非常广泛，主要是用在机械以及电子，汽车以及建筑和生活用品等领域，它通常具备有下面所说的特点：

PC film can be said to be a kind of amorphous, odorless, non-toxic and highly transparent colorless or slightly yellow engineering plastics thermoplastic sheet, PC thin films are widely used, is mainly used in machinery and electronics, automobile and construction and daily necessities, it usually has the following characteristics say:

1.PC薄膜具备有优良的一种物理机械的性能。

1.PC thin film has excellent physical and mechanical properties.

2.耐冲击性比较优秀，拉伸强度以及弯曲强度、压缩的强度比较高;蠕变性较小，尺寸相对来讲比较稳定。

2 excellent impact resistance, tensile strength and bending strength, compression strength is relatively high; creep is small, the size is relatively stable.

3.它具备有比较良好的耐热性达到125度以及耐低温性的零下45度，在比较宽的温度范围当中具备有着稳定的一种力学性能，另外尺寸的稳定性，电性能和阻燃性，可以在-60到120度下面长期的进行使用;没有明显熔点，在220到230度的呈熔融状态;因为分子链的刚性大，以及树脂的熔体粘度比较大。

3 it has good heat resistance and low temperature resistance up to 125 degrees 45 degrees below zero, in the relatively wide temperature range has a stable mechanical properties, and size stability, electrical properties and flame retardant properties, can be -60 to 120 degrees below the long-term use; no obvious melting point in the molten state, is 220 to 230 degrees; because of the rigidity of the molecular chain, and the melt viscosity of resin is relatively large.

4.吸水率较小，收缩率小以及尺寸的精度较高，尺寸稳定性比较好以及薄膜透气性小;属于是一种自熄性的材料;

4 the water absorption rate is small, the shrinkage rate is small and the precision of the dimension is high, the dimensional stability is good, and the permeability of the film is small;

5.对于光的稳定，但是pc薄膜不耐紫外光，耐候性相对比较好;耐油以及耐酸、不耐强碱和氧化性酸及胺、酮类，溶过氯化烃类与芳香族溶剂，长期在水里面比较容易引起水解以及开裂，缺点就是因为抗疲劳的强度比较差，容易产生一种应力开裂，抗溶剂的性能差，耐磨性也欠佳。

5 for light stability, but the PC film is UV resistant, weather resistance is relatively good; oil resistance and acid resistance, alkali resistance and non oxidizing acids and amines, ketones, aromatic hydrocarbons and soluble chloride solvent, long in the water are prone to hydrolysis and cracking, it is because of the disadvantages of anti fatigue strength poor, easy to produce a stress cracking resistance, solvent resistance is poor, poor.
