What are the best impact-resistant polymers for WPC ottoman cores?

When selecting materials for WPC (Wood-Plastic Composite) ottoman cores, impact resistance is a critical factor to ensure durability and longevity. The best impact-resistant polymers for this purpose include:

1. High-Density Polyethylene (HDPE): Known for its toughness and resistance to impacts, HDPE is a popular choice for WPC cores. It offers excellent durability and is resistant to moisture, making it ideal for indoor and outdoor furniture.

2. Polypropylene (PP): PP is lightweight yet highly impact-resistant, with good fatigue resistance. It’s often used in WPC applications where flexibility and strength are required.

3. Acrylonitrile Butadiene Styrene (ABS): ABS combines strength, rigidity, and impact resistance, making it suitable for high-stress applications. It’s also easy to mold, allowing for intricate ottoman designs.

4. Polycarbonate (PC): While more expensive, PC offers exceptional impact resistance and transparency options. It’s often blended with other polymers to enhance WPC core performance.

5. Thermoplastic Polyurethane (TPU): TPU provides excellent elasticity and impact absorption, making it perfect for ottomans that require both comfort and durability.

For optimal performance, consider blending these polymers with wood fibers or other additives to enhance their properties. Each material has unique benefits, so choose based on your specific needs for strength, cost, and environmental conditions.

By selecting the right impact-resistant polymer, you can ensure your WPC ottoman core remains sturdy and long-lasting, even under heavy use.
