High-Density Oxidized Polyethylene Wax (HD OPE Wax) is a high-performance polyethylene derivative with many unique properties and a wide range of applications. It enhances the lubricity and thermal stability of polyethylene by introducing its oxidizing groups into the molecular chain of polyethylene. The following are the main features of high-density oxidized polyethylene wax and its role in applications such as PVC foam boards:

Key features:
Excellent lubricating properties

Internal lubrication: During processing, HD OPE wax acts as an internal lubricant to reduce friction between PVC particles and improve the fluidity of the melt.
External lubrication: As an external lubricant, it can reduce the friction between the PVC melt and the contact surface of the equipment, prevent the melt from adhering to the surface of the equipment, and improve the extrusion efficiency.
Excellent thermal stability

Resistance to high-temperature degradation: HD OPE wax can improve the thermal stability of PVC during high-temperature processing, preventing PVC degradation and discoloration.
Excellent surface properties

Smooth surface: In PVC foam board, HD OPE wax can significantly improve the smoothness of the surface of the product, making it more beautiful and practical.
Gloss control: the ability to adjust the surface gloss of the product to the desired gloss (matte or high-gloss).
Improved mechanical properties

Improved impact strength: HD OPE wax enhances the impact strength of PVC foam boards, making them more durable.
Improved Dimensional Stability: Helps maintain the dimensional stability of the product, ensuring that the foam board retains its shape and size under a wide range of environmental conditions.
Good compatibility

Homogeneous dispersion: HD OPE waxes improve the homogeneous dispersion of other additives (e.g., stabilizers, pigments, fillers, etc.) in the PVC matrix, ensuring consistent product performance.
The role of PVC foam board
Lubricating effect

Reduced processing temperature: Through its excellent lubricating properties, HD OPE wax is able to reduce the processing temperature required during the extrusion process, prevent PVC degradation and extend the life of the equipment.
Increased production efficiency: Improved melt flow, allowing for higher extrusion speeds and production efficiency, resulting in lower production costs.
Improves surface quality

Smooth surface: The use of HD OPE wax can make the surface of the foam board smoother, suitable for subsequent printing, lamination or coating.
Gloss adjustment: Adjust the surface gloss of the foam board as needed to meet the needs of different applications.
Enhanced mechanical properties

Improved impact strength and toughness: HD OPE wax enhances the impact strength and toughness of PVC foam boards, making them more durable and reliable in a variety of applications.
Improved dimensional stability: Improve the dimensional stability of the foam board to ensure consistent performance in different environments.
Improved cell structure

Delicate and uniform cell structure: HD OPE wax can help control the size and structure of the bubble holes, so that the foam board has a uniform and delicate cell structure, and improve the thermal insulation performance and mechanical strength of the product.
conclusion
The application of high-density oxidized polyethylene wax in PVC foam board can significantly improve the processability, surface quality and mechanical properties of products, and is an indispensable and important additive. By improving lubricity, thermal stability, and cell structure, HD OPE wax enables PVC foam boards to be widely used in construction, advertising, packaging, and other fields.
