How does the addition of talc or other fillers affect polypropylene flower box properties?
The addition of talc or other fillers to polypropylene (PP) significantly alters the properties of flower boxes made from this polymer. Talc, a common mineral filler, enhances rigidity and heat resistance while reducing material costs. Filled PP flower boxes exhibit improved dimensional stability and reduced shrinkage during molding, making them more durable for outdoor use. However, excessive filler content may decrease impact resistance and flexibility, potentially leading to brittleness. Other fillers, such as calcium carbonate or glass fibers, offer varying benefits like increased weight for wind resistance or enhanced UV stability. Manufacturers balance filler ratios to optimize mechanical performance, aesthetics, and production economics for garden applications.
