How does the inclusion of mineral fillers enhance the rigidity of polypropylene outdoor ottomans?
The inclusion of mineral fillers in polypropylene outdoor ottomans significantly enhances their rigidity, making them more durable and stable for outdoor use. Mineral fillers, such as talc or calcium carbonate, are added to the polypropylene matrix to improve mechanical properties. These fillers increase stiffness by reinforcing the polymer structure, reducing deformation under load. Additionally, they improve dimensional stability, preventing warping in varying weather conditions. The result is a lightweight yet sturdy ottoman that withstands outdoor elements while maintaining structural integrity. This makes mineral-filled polypropylene an excellent choice for long-lasting outdoor furniture.
