How do the melting points of these plastics affect their suitability for outdoor flower boxes?
The melting points of plastics play a crucial role in determining their suitability for outdoor flower boxes. Plastics with higher melting points, such as polypropylene (PP) or high-density polyethylene (HDPE), are more resistant to heat and sunlight, making them ideal for outdoor use. These materials can withstand summer temperatures without warping or degrading. In contrast, plastics with lower melting points, like polystyrene (PS), may deform or weaken under direct sunlight or high temperatures, reducing their longevity in outdoor settings. Choosing the right plastic ensures durability, structural integrity, and long-term performance for garden containers exposed to varying weather conditions.
