PA612又称聚酰胺612或尼龙612,成分为聚十二烷二酰己二胺。PA612除具有一般PA特点外,还具有相对宽度小,更低的吸水率和密度,尺寸稳定性好的优点,有较高的拉伸强度和冲击强度,透明度。



用途

PA612主要用于:制高级牙刷和其它工业用鬃丝,也可用于制作精密机械部件和电线电缆被覆涂层、输油管、耐油绳索、传送带、轴承、衬垫等,军工上可用于制枪托、钢盔和军用电缆等



尼龙612制品常见缺陷与处理
注塑压力不稳定
一般这种情况同注塑机的射咀孔过小有关,因为射咀是同模具长期接触的,模具温度很低20-90 ℃,射咀温度240-280 ℃,他们之间存在温差难免会发生热交换,当射咀的温度降到尼龙的熔点以下时,射咀孔被冻结,在下次注射时得大的压力冲开,造成压力损失产生*注,但这时加大注塑压力后,生产几模后又会涨模。从现象看是注塑机注塑不稳定,其实是射咀孔过小,加大射咀孔这个现象就会消失。
