What are the differences in heat deflection temperatures between plastic outdoor armchair materials?
When selecting plastic outdoor armchairs, understanding heat deflection temperature (HDT) is crucial for durability. HDT measures the temperature at which a material deforms under load. Common materials like polypropylene (PP), high-density polyethylene (HDPE), and polycarbonate (PC) vary significantly in HDT. PP typically has an HDT of around 60-80°C, while HDPE ranges from 40-60°C. PC excels with an HDT of 130-140°C, making it ideal for high-heat environments. Factors like UV resistance and load capacity also influence performance. Choose wisely based on climate and usage to ensure long-lasting outdoor furniture.
