What resin grades are optimal for rotational molding of WPC armchair components?

When selecting resin grades for rotational molding of Wood-Plastic Composite (WPC) armchair components, it's essential to prioritize materials that balance durability, flexibility, and ease of processing. Polyethylene (PE) resins, particularly high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE), are widely preferred due to their excellent melt flow properties, impact resistance, and compatibility with wood fibers. These resins ensure uniform distribution during the rotational molding process, resulting in strong, lightweight, and weather-resistant armchair parts. Additionally, additives like UV stabilizers and coupling agents can further enhance the performance and longevity of WPC components. By choosing the right resin grade, manufacturers can achieve high-quality, sustainable furniture with optimal structural integrity.
