pa6是什么材质
PA6为乳白色或微黄色透明到不透明角质状结晶性聚合物,可自由着色,韧性、耐磨性、自润滑性好、刚性小、耐低温,耐细菌、能慢燃,离火慢熄,有滴落、起泡现象,成型加工性极好:可注塑、吹塑、浇塑、喷涂、粉末成型、机加工、焊接、粘接。
PA6是吸水率更高的PA,尺寸稳定性差,并影响电性能(击穿电压)。PA6的化学物理特性和PA66很相似,然而,它的熔点较低,而且工艺温度范围很宽。它的抗冲击性和抗溶解性比PA66要好,但吸湿性也更强。
因为塑件的许多品质特性都要受到吸湿性的影响,因此使用PA6设计产品时要充分考虑到这一点。为了提高PA6塑胶原料的机械特性,经常加入各种各样的改性剂。玻璃就是最常见的添加剂,有时为了提高抗冲击性还加入合成橡胶,如EPDM和SBR等。
对于没有添加剂的产品,PA6的收缩率在1%到1.5%之间。成型组装的收缩率主要受材料结晶度和吸湿性影响。实际的收缩率还和塑件设计、壁厚及其它工艺参数成函数关系。
pa6是什么材料
pa6是一种结晶性质的聚合物材料。
pa6又名尼龙6,其单体为己内酰胺,是由己内酰胺聚合而成的高分子化合物。尼龙6具有热塑性、轻质、韧性好、耐化学品和耐久性好等特性,一般用于汽车零部件、机械部件、电子电器产品、工程配件等产品。

PA6在工业中的应用:
聚酰胺玻纤增强材料可根据产品的特性要求添加玻纤含量在5-60%的范围,这类材料具有很好的强度、耐热性能、优良的抗冲击性能、良好的尺寸稳定性及低翘曲性等。为了满足在工业品方面的使用要求,增强聚酰胺材料应具备以下要求:
1、优异的强度和耐久性,优良的刚性和耐热性的结合。
2、优异的着****能,完美的表面外观,能够适用于复杂的结构成型,并帮助设计开发者开发新造型产品。
3、良好的加工性,优异的流动性及热稳定性使材料加工条件更为宽松,使注塑件微型化。
4、极高的热稳定性,能在高达270度的波峰焊锡中不挂锡。
