关于此产品
聚氯乙烯树脂,CAS 9002-86-2,此处以悬浮聚合白色粉末形式供应,采用中国SG牌号体系。SG编号与分子量成反比:SG1对应最高K值,SG8对应最低K值。 该编号决定树脂可用于制作何种制品。高K值树脂分子链长,可提供强度和韧性,但熔体黏度高,因此需要更多增塑剂,适用于要求较高的软制品。低K值树脂流动性好,适用于硬质注塑和薄壁瓶,此类制件必须在降解前充满模腔。SG5居中,是大多数管材、型材和硬质板材背后的通用牌号。 各牌号的标称用途:SG1和SG2用于高级电镀绝缘材料、薄膜及普通软制品;SG3用于屏蔽电线电缆、农用薄膜及全塑凉鞋;SG4用于工农业薄膜、软管及高强度管材;SG5用于透明制品、硬管、PVC管材、型材、线管、板材及热收缩膜;SG6用于唱片及透明片材、硬质板、焊条及纤维;SG7用于瓶类及透明材料、硬质注塑管及过氯乙烯树脂;SG8用于瓶类、片材、压延、硬质注塑、模压管材、管件及发泡板。 树脂来自中国主要生产企业,包括Ordos、Zhongtai、Tianye、Beiyuan、Junzheng、Sanlian、Dagu、Cangzhou Chemical、Sanyou、Sinopec、Xinfa、Hanwha、Ningbo Formosa、Shanghai Chlor-alkali、Guangxi Huayi和Ningxia Younglight。请依据采购规格确认生产厂家和牌号。
