How To Choose The Right Oxidized Wax For PVC Hose

In the production of PVC hose, oxidized wax (especially oxidized polyethylene wax) as an important additive plays a multi-faceted role. The following is a detailed analysis of the use of oxidized wax in PVC hose:

1. Introduction to oxidized wax

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

2. The role of oxidized wax in PVC hose

Improve transparency:

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

Enhance demoulding performance:

As a lubricant, oxidized wax can effectively improve the demoulding performance of PVC hoses, making the production process smoother.

Improve plasticization quality:

During the plasticization process of PVC hoses, oxidized wax can promote the dispersion of various materials in the formula, make the mixing more uniform, and thus improve the plasticization quality.

Improve surface finish:

Adding oxidized wax can significantly improve the surface finish of PVC hoses and improve the appearance quality of products.

Protect equipment:

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

III. Application precautions

Choose appropriate oxidized wax:

According to the specific requirements and production process of PVC hoses, choose the appropriate type and amount of oxidized wax.

Control the amount of addition:

Excessive oxidized wax may affect the physical properties and processing performance of PVC hoses, so the amount of addition needs to be strictly controlled.

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, demoulding performance, plasticization quality and surface finish of the product, and protect the production equipment. However, its application also needs to pay attention to the selection of appropriate types and addition amounts, and consider the synergistic effect with other additives.
