PA在室温下的拉伸强度和冲击强度都较高，但冲击强度不如PC和POM高。随温度和湿度的升高，拉伸强度急剧下降，而冲击强度则明显提高。玻璃纤维增强PA的强度受温度和湿度影响较小。PA的耐疲劳性较好，仅次于POM，玻纤增强处理后还可提高50%左右。PA的抗蠕变性较差，不适于制造精密的受力制品，但玻纤增强后可改善。PA的耐摩擦性和耐磨损性优良，是一种常用的耐磨性塑料品种。其中，不同品种的摩擦因数相差不大，无油润滑摩擦因数仅为0.1～0.3。耐磨性以PA1010***佳。PA中加入二硫化钼、石墨、F4及PE等可进一步改进摩擦性和耐磨性。

塑料***之光稳定剂分类与原理：
光稳定剂是橡胶塑料材料中重要的添加剂，主要用来抑制或减缓橡塑制品光老化。
1、光老化概念：材料在光的作用下，发生物理或化学变化，导致材料性质发生变化，比如变脆、发硬、变黄等，性能下降甚至无法继续使用。
2、防止材料光老化的措施：常常是添加光稳定剂，抑制或减缓光氧化降解，添加含量一般为0.01-0.5%。
A) the first line of Defense: Light Shielding agents, also known as Opacifiers, absorb or reflect UV functions, such as carbon black, zinc oxide, inorganic pigments (Zinc Barium) . B) Second Line of Defense: UV absorbers, such as salicylates, Benzophenone, and Benzotriazole. Benzotriazole to 400 NM above the visible light absorption, so does not affect the color of products. C) Third Line of Defense: quenchants, which transfer the excited state energy generated by the material&＃39;s absorption of ultraviolet light and prevent the formation of free radicals, are mainly metal complexes, such as organic complexes of nickel and cobalt. D) Fourth Line of Defense: free radical scavengers, such as hindered amines, remove free radicals from the material due to light and cut the chain of automatic oxidation. The crystallization occurs during PA molding, and the degree of crystallinity is greatly affected by the processing conditions. PA water absorption rate is relatively large, before processing must be dry, so that the water content is less than 0.1% . The drying conditions were 100 °C ~ 110 °C for 10 ~ 12 hours. PA products need to be humidified after molding to reduce the impact of water absorption on the performance and improve dimensional stability. PA is easy to produce internal stress in processing, so annealing treatment should be carried out. Oh, Shit
