What are the superior properties of PC sheets?
关于 PC 片材的优越性能，主要是：
Regarding the superior properties of PC sheets, the main ones are:
一、具有良好的耐热性达 125 度和耐低温性零下 45 度，在较宽的温度范围内具有稳定的力学性能，尺寸
稳定性，电性能和阻燃性，可在-60~120℃下长期使用；无明显熔点，在 220-230℃呈熔融状态；由于分
子链刚性大，树脂熔体粘度大；
- It has good heat resistance up to 125 degrees and low temperature resistance of minus 45
degrees. It has stable mechanical properties, dimensional stability, electrical properties and flame
retardancy in a wide temperature range, and can be used at -60~120℃ It has no obvious melting
point and is in a molten state at 220-230℃; due to the high rigidity of the molecular chain, the
resin melt viscosity is high;
二、对光稳定，但不耐紫外光，耐候性好；耐油、耐酸、不耐强碱、氧化性酸及胺、酮类，溶于氯化烃类
和芳香族溶剂，长期在水中易引起水解和开裂，缺点是因抗疲劳强度差，容易产生应力开裂，抗溶剂性差，
耐磨性欠佳。
- Stable to light, but not resistant to ultraviolet light, good weather resistance; resistant to oil,
acid, strong alkali, oxidizing acids, amines, and ketones. It is soluble in chlorinated hydrocarbons
and aromatic solvents, and can easily cause damage when exposed to water for a long time.
Hydrolysis and cracking, the disadvantages are that it is prone to stress cracking due to poor
fatigue resistance, poor solvent resistance, and poor wear resistance.
三、耐冲击性优异，拉伸强度、弯曲强度、压缩强度高；蠕变性小，尺寸稳定。
- Excellent impact resistance, high tensile strength, bending strength and compressive strength;
small creep property and stable dimensions.
四、吸水率小，收缩率小，尺寸精度高，尺寸稳定性好，薄膜透气性小；属自熄性材料；
- Low water absorption, small shrinkage, high dimensional accuracy, good dimensional stability,
low film permeability; it is a self-extinguishing material;
五、具有优良的物理机械性能。
- It has excellent physical and mechanical properties.
