Common Modification Methods And Applications Of PVC Materials

Common modification methods and applications of PVC materials, polyvinyl chloride (PVC or vinyl) is an economical and versatile thermoplastic polymer, widely used in the construction and building industry, production of door and window profiles, pipes (drinking water and wastewater), wire and cable insulation, medical equipment, etc. It is one of the world’s three major thermoplastic materials along with polyethylene and polypropylene, and polyethylene wax plays an important role in PVC pipes.

The role of polyethylene wax for PVC pipes:

1. Reduce the occurrence of fouling.

2. It can give calendering, extrusion, injection and blow molding equipment excellent metal peeling properties.

3. Make the surface gloss of the product better.

4. It does not affect the transparency of the PVC mixture, and the dosage range is about one thousandth to five thousandths.

5. No separation or migration will occur within a reasonable dosage range.

6. Even in the case of high-temperature processing of PVC, it can maintain excellent viscosity.

7. While increasing the extrusion speed, it has no effect on the appearance.

8. Make the PVC pipe also have excellent stability under high temperature conditions.
9. Minimize the processing energy consumption of PVC during extrusion molding.
10. Improve the filler dispersion of PVC and improve the impact strength.

Polyethylene wax varieties include low molecular weight polyethylene wax, oxidized polyethylene wax, etc., which can be widely used in the production process of PVC. Polyethylene wax is used in the production process of PVC pipes. It is mainly used as an external lubricant and has many other functions.

Application industry:

Widely used in the manufacture of masterbatch, granulation, plastic steel, PVC pipes, hot melt adhesives, rubber, shoe polish, leather brightener, cable insulation, floor wax, plastic profiles, inks, injection molding and other products.
