pa6 美国杜邦 73g35hsl的性能：

一般性能 :

pa的外观为透明或不透明乳白色或淡黄色的粒料，表观角质、坚硬，制品表面有光泽。  pa的吸水率比较大，酰胺基的比例越大，吸水率越高。pa属于自熄性塑料，燃烧时有烧焦的羊毛或指甲味。pa属中等阻隔性塑料，阻隔性随酰胺基/亚甲基的比例增大而提高，以pa6的阻隔效果。pa6的o2透过系数为25～40㎝3-㎜/㎡-d-mpa

co2透过系数为150～200㎝3-㎜/㎡-d-mpa

h2o透过系数为150g-㎜/㎡-d-mpa。

力学性能:

 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。

Huayun plastic company PA good friction and wear resistance, is a commonly used wear-resistant plastic varieties. Among them, the friction coefficient of different kinds of oil-free lubrication is only 0.1 ~ 0.3. WEAR RESISTANCE TO PA1010. The addition of Molybdenum disulfide, graphite, F4 and pe to PA can further improve the friction and wear resistance. Thermal properties: the thermal deformation temperature of PA is not high, generally at 50 ~ 75 °C. After reinforced with glass fiber, the thermal conductivity up to 200 °C PA is very small, only 0.16 ~ 0.4 w / m-k. The LINEAR EXPANSION COEFFICIENT OF PA was larger and decreased with the increase of crystallinity. Environmental Properties: PA Good Chemical Stability, can withstand most organic solvents such as alcohol, aromatics, esters and Ketones, especially oil resistance outstanding. But PA has poor acid-resistance, alkali-resistance and salt-resistance, which can lead to swelling, and the inorganic salt is zinc chloride. PA is soluble in formic acid and phenolic compounds. PA light resistance is not good, in the sun, the intensity will soon decline and become brittle, so can not be used outdoors.
