    关于此产品

    悬浮法 PVC 树脂(聚氯乙烯,CAS 9002-86-2)以白色粉末供应,按中国 SG 体系分级,从 SG1 到 SG8。牌号数字与分子量呈反向关系:SG1 的 K 值最高,SG8 最低。

    K 值决定了树脂的加工性能及适用范围。在高端,长聚合物链带来强度和韧性,但熔体粘度也高,因此这些牌号需添加更多增塑剂,适合性能要求高的软制品。在低端,树脂流动性好,适合硬质注塑和薄壁瓶,此类加工中熔体必须在开始降解之前充满模具。处于中间的 SG5 是大多数管材、型材和硬片的主力牌号。

    各牌号的标称用途如下。SG1 和 SG2:电镀用绝缘材料、膜材及一般软制品。SG3:屏蔽电线电缆、农用薄膜和全塑凉鞋。SG4:工业和农用薄膜、软管和高强度管。SG5:透明制品、硬管、PVC 管、型材、电线导管、板材和热收缩膜。SG6:透明片材、硬板、焊条和纤维。SG7:瓶、透明材料和硬质注塑管。SG8:瓶、片材、压延制品、硬质注塑制品、模压管、管件和发泡板。

    该树脂来自中国主要生产商,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。以 25 kg 袋或吨袋包装。请对照您的采购规格核对生产商和牌号。现行规格、安全数据及可提供的批次文件可应要求提供。
