PVC制品專用蠟

本系列產品主要應用于PVC管材、型材、板材、片材及電線電纜等PVC制品的生產加工中，具有以下特點：

（1）、在PVC制品成型加工過程中做分散劑、潤滑劑和光亮劑。

（2）、在PVC制品加工時可提供優良的抗粘連和控制流動的作用。

（3）、對PVC制品的物理性能無不良影響，與脂肪酸類潤滑劑相比，不會對熔體張力和維卡軟化點帶來不利影響。

（4）、良好的相容性，本品具有非常強的極性中心及很長的非極性碳鏈，結構中在極性上與塑料相容的部分起內潤滑作用，在極性上與塑料不相容的部分起外潤滑和脫模的作用。

（5）、可控制熔融時間，在特殊加工方法中可用本復合蠟來控制熔融，即使加入量很大也能與其他成分有很好的相容性。

（6）、低揮發性，由于本品軟化點高，不容易揮發，此項特性對壓延和真空脫氣的工藝極其重要。

主要型號：

本產品為塑編包裝，25公斤/袋，避光避濕保存，建議添加份量0.5%-1%。

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%.
