PC薄膜片材可以說是一種無定型以及無臭、無毒和高度透明的無色或者是微黃色的熱塑性工程塑料，PC薄膜的片材應(yīng)用得非常廣泛，主要是用在機(jī)械以及電子，汽車以及建筑和生活用品等領(lǐng)域，它通常具備有下面所說的特點(diǎn)：
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薄膜具備有優(yōu)良的一種物理機(jī)械的性能。
1.PC thin film has excellent physical and mechanical properties.
2.耐沖擊性比較優(yōu)秀，拉伸強(qiáng)度以及彎曲強(qiáng)度、壓縮的強(qiáng)度比較高;蠕變性較小，尺寸相對來講比較穩(wěn)定。
2 excellent impact resistance, tensile strength and bending strength, compression strength is relatively high; creep is small, the size is relatively stable.
3.它具備有比較良好的耐熱性達(dá)到125度以及耐低溫性的零下45度，在比較寬的溫度范圍當(dāng)中具備有著穩(wěn)定的一種力學(xué)性能，另外尺寸的穩(wěn)定性，電性能和阻燃性，可以在-60到120度下面長期的進(jìn)行使用;沒有明顯熔點(diǎn)，在220到230度的呈熔融狀態(tài);因?yàn)榉肿渔湹膭傂源�，以及樹脂的熔體粘度比較大。
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.吸水率較小，收縮率小以及尺寸的精度較高，尺寸穩(wěn)定性比較好以及薄膜透氣性小;屬于是一種自熄性的材料;
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.對于光的穩(wěn)定，但是pc薄膜不耐紫外光，耐候性相對比較好;耐油以及耐酸、不耐強(qiáng)堿和氧化性酸及胺、酮類，溶過氯化烴類與芳香族溶劑，長期在水里面比較容易引起水解以及開裂，缺點(diǎn)就是因?yàn)榭蛊诘膹?qiáng)度比較差，容易產(chǎn)生一種應(yīng)力開裂，抗溶劑的性能差，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.
