This standard is a design guideline for the recyclability and regeneration of high-density polyethylene (PE-HD) materials. It guides product designers on how to optimize products from the source to make them easier to process and regenerate within recycling systems. Its core purpose is to direct product design by selecting appropriate base resins, colors, additives, and other elements, while also evaluating the recyclability and regenerability of the products. To support this evaluation, the standard provides relevant testing methods. When implementing these tests, it typically involves using a melt flow indexer to assess the material's flow properties, as well as Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) to analyze the material's chemical structure and thermal properties.
