High Density Oxidized Polyethylene Wax

ZM-118 is a high-density, high-viscosity oxidized polyethylene wax with elevated acid value, specifically engineered for high-filled and high-performance polymer systems. It offers an excellent balance of dispersion, lubrication, and interfacial compatibility, making it particularly suitable for applications requiring structural stability and consistent processing performance. Its performance profile is comparable to high-end oxidized waxes such as AC-316, providing a cost-effective alternative without compromising performance.

Key Features & Technical Mechanism

• ZM-118 is produced through a controlled oxidation process of polyethylene.
• By carefully adjusting oxidation degree and molecular structure, the product achieves a balance between high molecular weight and suitable polarity.
• Precise control of reaction temperature, oxidation time, and catalytic conditions ensures consistent melting point, viscosity, and acid value across batches.
• The material is then processed into granules or powder, ensuring stable morphology and good handling properties.

Structural Reinforcement Capabilities

Due to its high molecular weight and viscosity, ZM-118 forms a relatively stable three-dimensional structural network within the polymer matrix during processing. This structure helps to stabilize the distribution of fillers and reduce phase separation caused by processing fluctuations, thereby enhancing the overall stability of the system.

Polar Interfacial Interaction

The high acid value confers good polarity to the product, enabling it to form effective interfacial interactions with inorganic fillers (such as calcium carbonate and aluminum hydroxide). This enhances compatibility between the fillers and the resin, thereby improving dispersion and enhancing mechanical properties.

High-Temperature Processing Stability

Thanks to its high melting point, ZM-118 maintains stable performance under high-temperature processing conditions, effectively reducing issues such as precipitation and migration, and ensuring excellent stability and consistency throughout continuous production.

Compatibility with High-Filler Systems

In high-filler systems, ZM-118 effectively improves filler distribution and enhances system flowability while maintaining structural integrity, making it suitable for high-load applications.
