High-density polyethylene (HDPE) is known for its low absorptivity, making it resistant to water and most chemicals. However, when considering its absorptivity towards black colors or pigments, the context often shifts towards its application in production, particularly in the recycling or manufacturing of plastic products. Black pigments, primarily carbon black, are extensively used in HDPE to provide UV protection and enhance mechanical properties. This pigment has a high level of UV stability and extends the life of products exposed to sunlight. In the recycling process, black-colored HDPE might pose challenges in sorting technologies, as the black pigment can absorb infrared signals used in automatic sorting, making these plastics harder to recycle. Innovations in pigment technology and recycling methods continue to evolve to address these challenges. Hence, while HDPE itself has low absorptivity, the addition of black pigments impacts its properties and recyclability.
