pa46成型溫度是多少?
PA66的成型溫度為260-300度。PA46是通過丁二胺和己二酸縮聚形成的脂肪族聚酰胺。盡管StanylPA46具有與尼龍66相似的分子結構,但在給定的鏈長和更對稱的鏈結構上具有更多的酰胺基;并且高度對稱的鏈結構使其具有較高的結晶度(約70%),并且結晶速度快,因此熔點較高(295℃),熱變形溫度也較高,并且長期使用溫度為(切割5000小時)可達到163℃。這些特性使StanylPA46在耐熱性,高溫機械強度,耐磨性等方面,比其他工程塑料(如PA6,PA66,PPA和聚酯)具有技術優勢,并且成型周期短,加工更經濟。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
