    PVC 外润滑剂

    PVC 外润滑剂 – Specialty chemicals product from Bio Green Chem

    关于此产品

    PVC 用润滑剂按其作用部位进行分类。外润滑剂与聚合物的相容性有限,因此会迁移至熔体表面,在混配料与螺杆、口模或辊筒的高温金属之间形成一层膜。这层膜控制着摩擦和脱模;若没有这层膜,PVC 会粘附在金属上并就地降解,留下沉积物,在挤出物上形成痕迹。 其代价在于,外润滑剂用量过多会延迟塑化,削弱型材熔接线的强度,并可能在口模上析出结垢。因此,牌号选择的关键在于使脱模效果与加工温度和剪切相匹配,这也正是提供系列牌号而非单一产品的原因。 其中一个牌号适用于 PVC 加工、母粒及橡胶润滑。第二个牌号有粉末和白色圆片两种形态,用于管材、管件和发泡板。第三个牌号涵盖 PVC 加工、母粒、热熔胶和道路标线,第四个牌号则在此基础上增加了 CPVC 加工。L-G70S 为淡黄色粉末或片状物,用于粒料、板材及压延膜加工,采用带 PE 内衬的纸箱包装。L-G74 为浅黄色至白色固体,用作硬质 PVC 型材、板材、管件及百叶窗的外润滑脱模剂。
