WPC PE HDPE LDPE Lubricant L-M for Wood Plastic Composites Plates and Profiles

Product Name：
WPC PE HDPE LDPE Lubricant L-M for Wood Plastic Composites Plates and Profiles

Special Instruction:

Product Introduction：

1. Product Overview：
L-M is a high-performance lubricant specifically formulated for WPC PE/PP and WPC HDPE/LDPE product manufacturing. As a multi-component additive combining stearic acid, polyethylene wax, ethylene distearate amide, and other auxiliary lubricants, it promotes fusion and delivers excellent lubrication throughout the processing cycle. This additive is widely used in wood-plastic composite decking, profiles, sheets, and injection-molded parts, where consistent melt flow, uniform filler dispersion, and smooth surface quality are essential for high-quality production.

2. Product Principle：
L-M functions through a synergistic lubrication mechanism. The stearic acid and polyethylene wax components provide internal lubrication by reducing friction between polymer chains, lowering melt viscosity and improving flow characteristics. Ethylene distearate amide contributes external lubrication by reducing friction between the melt and processing equipment surfaces, preventing sticking and ensuring smooth material flow. This balanced lubrication system promotes uniform fusion of the polymer matrix with wood fibers and other fillers, creating a homogeneous composite structure. The result is improved melt homogeneity, reduced melt pulsation, and enhanced processing stability.

3. Performance Characteristics：
L-M offers exceptional fineness (≥99% through 0.05mm sieve), ensuring rapid and uniform dispersion throughout WPC compounds. The odorless formulation creates a pleasant working environment and is suitable for indoor applications. Melting point of 147°C ensures complete fusion during typical WPC processing temperatures while maintaining thermal stability. Free acid value of 0.42 indicates consistent quality and controlled reactivity. The additive effectively reduces melt viscosity and friction, enabling higher extrusion speeds, lower energy consumption, and reduced equipment wear. It also improves surface smoothness and reduces defects such as die lines, plate-out, and roughness.

4. Usage and Dosage：
Recommended addition level is 1.5–2.5% based on total formulation weight, depending on wood flour content, processing conditions, and desired product properties. For standard WPC profiles and decking, 1.8–2.2% typically provides optimal fusion promotion and lubrication. For high-filler formulations (wood content >60%) or complex profile geometries, dosages toward 2.5% may be beneficial. Systematic trials should be conducted to optimize dosage for specific formulations, equipment, and target performance characteristics.

Product Advantages:

1. Promotes Efficient Fusion During Processing
L-M accelerates and enhances the fusion of polymer matrix with wood fibers and fillers, ensuring complete homogenization of the composite. This results in consistent melt properties and improved product quality across production runs.

2. Balanced Internal and External Lubrication
The synergistic combination of stearic acid, polyethylene wax, and ethylene distearate amide provides optimal internal and external lubrication. This balanced system reduces melt viscosity while preventing sticking, enabling smoother processing and higher production efficiency.

3. Excellent Dispersion and Uniformity
Ultra-fine particle size (≥99% through 0.05mm sieve) ensures rapid, homogeneous distribution throughout the compound. This eliminates localized variations in lubrication that can cause processing defects or inconsistent product properties.

4. Enhanced Product Strength and Homogeneity
L-M creates optimal conditions for interfacial bonding between polymer and wood fibers. It significantly improves tensile strength, flexural modulus, and impact resistance in finished WPC products while maintaining consistent properties across the cross-section.

5. Clean Processing and Surface Quality
The controlled lubrication system minimizes plate-out, die buildup, and surface defects. Products exhibit smooth, clean surfaces free from blemishes or irregularities, reducing finishing requirements and improving aesthetic appeal.

6. Odorless and Environmentally Friendly
The odorless formulation ensures a pleasant working environment and is suitable for indoor applications. L-M contains no harmful substances and complies with environmental standards for WPC production.

7. Consistent Quality and Reliable Performance
Rigorous quality control ensures batch-to-batch consistency in fineness, melting point, and free acid value. This reliability translates into predictable processing behavior and consistent product properties.

8. Versatile Application Across WPC Products
L-M performs effectively in diverse PE/PP and HDPE/LDPE-based WPC applications, from decking and fencing to automotive components and outdoor furniture, providing consistent lubrication and fusion promotion.
