The Role of Paraffin Emulsion in the Production of PVC Sheet

The Role of Paraffin Emulsion in the Production of PVC Sheet The Role of Paraffin Emulsion in the Production of PVC Sheet 2019/06/19

In the process of PVC sheet production, paraffin has a very long non-polar carbon chain with a very strong polar center. In the structure, the part compatible with plastic in polarity plays the role of internal lubrication, and the part incompatible with plastic in polarity plays the role of external lubrication and demoulding.Compared with fatty acid lubricants, paraffin has no favorable effect on melt tension and vicat softening point, and provides excellent adhesion resistance and flow control.

Wax emulsion production of KING HONOR INTERNATIONAL LTD. is to control melt, even large amount can have very good compatibility with other components. It has thousands of customers in the PVC industry, as a famous paraffin wax emulsion manufacturer. Paraffin is a known plastic lubricant that provides both internal and external lubrication (mold release effect) while maintaining a high degree of transparency and having little effect on gelation.

At the same time, the low volatility of paraffin is important for calendering and vacuum degassing in the process of die-casting PVC sheet. As a kind of internal lubricant, paraffin has good compatibility with polymer, which can reduce the intermolecular cohesion of polymer, so as to optimize the internal friction heat generation and melt fluidity of plastic melt.

The main function of the external lubricant is to optimize the friction between the polymer melt and the hot metal surface of the processing equipment. It has poor compatibility with polymers and has easy migration from inside the melt, so a thin layer of lubricant can be formed at the interface between the plastic melt and the metal.

Besides the application of paraffin emulsion in PVC board, it is also applied in pipe material, wire and cable, etc.

KING HONOR INTERNATIONAL LTD. was founded in 2008, with ten years of production experience. It is a famous domestic paraffin wax emulsion manufacturer, providing quality paraffin emulsion supply services for customers.  Welcome customers to come to inquire.
