相關標簽:奧地利SAX PA66、美國William Barnet & Son PA66、日本寶理 PA66塑料米、中等粘性 PA66、吹塑薄膜 PA66、Good/Clarity PA66塑料米

PA66:熔點252℃。PA6:熔點230-280℃。PA66(聚酰胺66或尼龍66),同PA6比擬,PA66更普遍使用于汽車產業、儀器殼體還有別的想要有抗打擊性和高強度要求的制品。聚酰胺樹脂,英文稱號為polyamide,簡稱PA。俗稱尼龍(Nylon),它是大份子主鏈反復單位中含有酰胺基團的高聚物的總稱。為五大工程塑估中產量最大、種類最多、用處最廣的種類。尼龍中的重要種類是尼龍6和尼龍66,占絕對主導地位,尼龍6為聚己內酰胺,而尼龍66為聚己二酸己二胺,尼龍66比尼龍6要硬l2%;其次是尼龍11,尼龍12,尼龍610,尼龍612,別的還有尼龍1010、尼龍46、尼龍7、尼龍9、尼龍13,新種類有尼龍6I、尼龍9T和特別尼龍MXD6(阻隔性樹脂)等,尼龍的改性種類數目繁多,如增強尼龍、單體澆鑄尼龍(MC尼龍)、反映注射成型(RIM)尼龍、芬芳族尼龍、通明尼龍、高抗沖(超韌)尼龍、電鍍尼龍、導電尼龍、阻燃尼龍,尼龍與其他聚合物共混物和合金等,滿足不同特別要求,普遍用作金屬,木料等傳統原料代用品。 。以上文獻若需轉載請備注出處:pbt塑料 //shanglikaiguan.cn/
