In the production of PVC hoses, oxidized wax (especially oxidized polyethylene wax) is an important additive that plays multiple roles. The following is a detailed analysis of the use of oxidized wax in PVC hoses:

1. Introduction to Oxidized Wax

Oxidized wax, especially oxidized polyethylene wax (OPE), is obtained by oxidizing polyethylene wax. Its molecules have polar functional groups such as carbonyl and hydroxyl, which increases compatibility with fillers, pigments, and polar resins (such as PVC). This compatibility enables oxidized wax to fully exert its lubricating, dispersing, plasticizing and other functions in the production process of PVC hoses.

2. The role of oxidized wax in PVC hoses

Improve transparency:

For PVC transparent hoses, adding polar oxidized wax can avoid affecting transparency and maintain product transparency.

Enhance demolding performance:

Oxidized wax, as a lubricant, can effectively improve the demolding performance of PVC hoses, making the production process smoother.

Improving plasticization quality:

During the plasticization process of PVC hoses, oxidized wax can promote the dispersion of various ingredients in the formula, making the mixture more uniform and thus improving the plasticization quality.

Improve surface smoothness:

Adding oxidized wax can significantly improve the surface smoothness of PVC hoses and enhance the appearance quality of the product.

Protection equipment:

Oxidized wax can also protect production equipment such as screws during the production process of PVC hoses, extending their service life.

3. Application precautions

Choose the appropriate oxidized wax:

Select the appropriate type and amount of oxidized wax according to the specific requirements and production process of PVC hoses.

Control the amount of addition:

Excessive oxidation wax may affect the physical and processing properties of PVC hoses, so it is necessary to strictly control the amount added.

Synergistic effect with other additives:

The application of oxidized wax in PVC hoses also needs to consider the synergistic effect with other additives (such as plasticizers, stabilizers, etc.) to ensure the overall performance of the product.

In summary, oxidized wax plays an important role in the production of PVC hoses, which can improve the transparency, demolding performance, plasticizing quality, and surface smoothness of products, and protect production equipment. However, its application also requires careful selection of appropriate types and amounts of additives, as well as consideration of synergistic effects with other additives.
