【Hanwei Technology · Product Introduction】PE Wood-Plastic Special Composite Lubricant: Solves the three major problems of precipitation, poor dispersion, and low production capacity.

Stock Code: 920957 | Technological accumulation of provincial-level R&D center | 230,000 tons production capacity guaranteed

In the large-scale production of PE wood-plastic (WPC), the lubrication system directly affects production efficiency, product appearance, production cost and long-term stability. Currently, the industry is facing four core pain points: high extrusion torque limits production capacity, poor dispersion of wood powder leads to appearance defects, lubricants are prone to migration and precipitation, and carbon deposits at the mold opening increase maintenance costs. As a professional supplier in the field of fatty acid derivatives and wood-plastic additives in China, Hanwei Technology (stock code: 920957) relies on the technical accumulation of its provincial R&D center and focuses on the processing needs of wood-plastic to launch a PE wood-plastic-specific composite lubricant, which can provide stable and efficient processing solutions for multiple scenarios such as PE wood-plastic flooring, wall panels, guardrails, and outdoor furniture.

This product adopts three core design elements to meet production requirements: Firstly, dual balance for both internal and external lubrication. Through a special lubrication formula, it can simultaneously meet the requirements of sliding within the melt and outside the mold. Tests show that the extrusion torque and main power current have decreased, which is beneficial for increasing the extrusion speed (results may vary depending on equipment conditions). Secondly, enhanced dispersion compatibility. The special molecular structure effectively breaks the agglomeration of wood powder, and according to the company's experiments, when combined with this lubricant, the density and surface defects of high-filling products have been significantly improved. Thirdly, low precipitation and high weather resistance. Selecting high-quality heat-resistant components to reduce migration rate helps to reduce the whitening and oil leakage problems in the product over a long period of exposure, thereby enhancing weather resistance (specific improvement in weather resistance performance is affected by the usage environment).

一、 Common Pain Points and Root Causes in the Industry

• Capacity efficiency is limited: The current industry-standard single PE wax-based lubrication system mainly focuses on the external lubrication effect, while the internal lubrication performance is relatively insufficient. This can lead to slow plasticization speed of materials, high extrusion torque, and high main power consumption, thereby restricting the potential for capacity improvement.
• Appearance quality is difficult to control: The natural compatibility between wood powder and the PE base material is relatively poor, resulting in agglomeration, which leads to numerous pores in the product, rough and uneven surface, insufficient density, and lowers the qualification rate of the finished product.
• Insufficient long-term stability: The traditional lubrication system usually contains low-molecular-weight components. During high-temperature processing and long-term use, these components tend to migrate and precipitate, causing the product to turn white and seep oil, thereby affecting the outdoor weather resistance performance.
• High difficulty in mass production control: Traditional lubrication solutions often require enterprises to mix multiple components by themselves. The formula debugging process is lengthy, and the parameter control is challenging. It is difficult for small and medium-sized enterprises to achieve long-term stable mass production.

二、Core advantages of Hanwei PE wood-plastic lubricant

1. Internal and external lubrication balance design

Taking into account both the lubrication requirements within the melt and outside the mold, this design helps to reduce the extrusion torque and the main power current, while increasing the extrusion speed and effectively extending the service life of the equipment and the screw.

2. Strong dispersion + Weak compatibility synergy

The special molecular structure design can effectively break the agglomeration of wood powder, improve the uniformity of filler dispersion, enhance the surface gloss and density of the products, and reduce the probability of the occurrence of defective products such as pinholes, pores, and broken strands.

3. Low leaching and resistant to migration

The molecular structure is highly compatible with the PE wood-plastic system. During the high-temperature processing, it has extremely low volatility, enhancing the long-term durability of the finished product and meeting the long-term weather resistance requirements for outdoor building materials.

4. Adding simplicity and high versatility

No need for complex multi-component compounding. The recommended addition amount is 1.5%–2.5% (which can be adjusted according to the proportion of wood powder). It is compatible with all mainstream production processes such as one-step extrusion, two-step extrusion, and twin-screw granulation.

三、Application effect

✅ The extrusion efficiency has been increased by 20% - 30%, and the energy consumption per unit production capacity has significantly decreased.

✅ The main circuit current drops by 15% to 25%, the equipment load decreases, and the service life is extended.

✅ The surface gloss of the product has been significantly improved, and the qualified product yield can reach 95% or higher.

✅ The carbon deposits in the mold cavities have been significantly reduced, and the mold cleaning cycle has been extended by more than 20%.

✅ Even when the amount of wood powder reaches 50% - 75%, stable production can still be achieved.

四、Typical application scenarios
