WPC Lubricant LE-D for PE/PP Wood Plastic Composite Non-Reactive Internal External Lubrication Additive

LE-D functions by reducing friction between polymer chains and between the polymer matrix and wood fibers during processing. This internal and external lubrication effect lowers melt viscosity, improves flow characteristics, and promotes uniform distribution of fillers throughout the composite. The absence of maleic anhydride (0%) prevents unwanted side reactions that could degrade the polymer or affect long-term durability. Instead, LE-D relies on a proprietary blend of non-reactive components that physically facilitate chain mobility and interfacial adhesion without chemically altering the base materials. This results in smoother extrusion, reduced energy consumption, and enhanced mechanical properties in the final product.

Performance Characteristics：
LE-D delivers exceptional blending homogenization, ensuring that wood flour and other additives are uniformly dispersed within the PE matrix. This homogeneity translates into consistent product quality and reduced variability across production runs. The lubricant significantly improves processability by lowering melt torque and pressure, enabling faster extrusion speeds and reducing wear on processing equipment. Its excellent dispersity prevents agglomerates and surface defects, yielding smoother finishes and higher dimensional accuracy. Moreover, LE-D is designed to withstand outdoor exposure, maintaining its effectiveness under UV radiation and temperature fluctuations without leaching or blooming.

Usage and Dosage：
Recommended addition level is 0.5–3% in WPC: 0.5–1.5% for better flow and surface finish of thin walled profiles, 2–3% for high filler (wood >60%) or high strength products. It can be added directly to the mixer or extruder; trials are suggested to optimize dosage.

1. Standalone Use Without Compatibilizers：
LE-D eliminates the need for separate compatibilizers, simplifying formulations and reducing raw material costs. Its unique chemistry provides both lubrication and interfacial bonding in a single additive, streamlining production and inventory management.

2. Enhanced Mechanical Strength：
By improving filler dispersion and reducing internal stress, LE-D significantly increases the tensile and flexural strength of WPC products. This reinforcement is particularly valuable for load-bearing outdoor applications such as decking and structural profiles.

3. Superior Processability and Surface Quality：
The lubricant reduces melt viscosity and friction, enabling smoother extrusion, higher line speeds, and lower energy consumption. Finished products exhibit excellent surface smoothness, free from die lines or rough textures, enhancing aesthetic appeal and marketability.

4. Environmentally Friendly Formulation：
LE-D is free from maleic anhydride and other hazardous substances, complying with global environmental standards for outdoor products. Its non-migrating nature ensures long-term performance without compromising ecological safety.

1. PE Wood-Plastic Decking and Flooring：
LE-D is widely used in WPC decking and flooring, where it enhances strength, weather resistance, and surface finish, ensuring long-lasting performance under outdoor conditions.

2. WPC Fencing and Railing Systems：
For fencing and railing, the lubricant improves dimensional stability and impact resistance while providing a smooth, splinter-free surface that withstands constant exposure.

3. Outdoor WPC Furniture：
In benches, tables, and seating, LE-D contributes to robust mechanical properties and aesthetic appeal, maintaining appearance and structural integrity despite seasonal weather changes.

4. WPC Cladding and Siding：
For exterior wall cladding, LE-D ensures uniform dispersion of wood fibers, preventing warping or cracking and delivering consistent color and texture across large panels.

5. Automotive and Marine WPC Components：
Specialized applications in automotive interiors or marine environments benefit from LE-D's durability and resistance to moisture, UV, and thermal cycling.
