What resin grades are optimal for high-speed WPC armchair extrusion?

When it comes to high-speed Wood-Plastic Composite (WPC) armchair extrusion, selecting the right resin grade is crucial for achieving optimal performance, durability, and production efficiency. The most suitable resin grades for this process typically include high-density polyethylene (HDPE) and polypropylene (PP), which offer excellent melt flow properties, thermal stability, and mechanical strength.

HDPE is favored for its high impact resistance and low moisture absorption, making it ideal for outdoor furniture applications. PP, on the other hand, provides superior flexibility and UV resistance, ensuring long-term color retention and structural integrity. Additionally, additives like coupling agents and lubricants can enhance the compatibility between wood fibers and resin, improving extrusion speed and product quality.

For manufacturers aiming to maximize output without compromising quality, blending these resins with optimized wood flour content (typically 40-60%) can strike the perfect balance between speed and performance. Always consult with material suppliers to tailor the resin formulation to your specific extrusion equipment and end-use requirements.
