PVC制品专用蜡

本系列产品主要应用于PVC管材、型材、板材、片材及电线电缆等PVC制品的生产加工中，具有以下特点：

（1）、在PVC制品成型加工过程中做分散剂、润滑剂和光亮剂。

（2）、在PVC制品加工时可提供优良的抗粘连和控制流动的作用。

（3）、对PVC制品的物理性能无不良影响，与脂肪酸类润滑剂相比，不会对熔体张力和维卡软化点带来不利影响。

（4）、良好的相容性，本品具有非常强的极性中心及很长的非极性碳链，结构中在极性上与塑料相容的部分起内润滑作用，在极性上与塑料不相容的部分起外润滑和脱模的作用。

（5）、可控制熔融时间，在特殊加工方法中可用本复合蜡来控制熔融，即使加入量很大也能与其他成分有很好的相容性。

（6）、低挥发性，由于本品软化点高，不容易挥发，此项特性对压延和真空脱气的工艺极其重要。

Wax specialized for PVC

The series products mainly used forPVC pipes, profiles, panel, sheets and wire & cable products.

Characteristics:

1.    Used as dispersant, lubricant and brightener in the PVC product forming process.

2.    Excellent anti adhesion and controlling fluid flow in the PVC product progress.

3.    No adverse effect on the physical properties of PVC products, compared with the fatty acid lubricant, no negative effect on the melt tension and VEKA softening point.

4.    Good compatibility: It has a very strong polar center and a long non-polar carbon chain. It will serve as internal lubricant in the parts which are compatible with the plastic in polarity, and will turn to be external lubricant & release agentin the partswhich are not compatible.

5.    Melting time can be controlled. The compound wax can be used to control the melting in particular processing methods. Even if adding a large amount, it can also have a good compatibility with the other components.

6.    Low volatility. Due to the high softening point, it is not likely to be volatile. This feature is extremelyimportant for calender and vacuum degassing process.

Main Models：

7.    Package and storage:

Packed in plastic bag, 25kg in weight. It should be stored in dry places and away from light. Reference feeding rate is 0.5%-1%.
