An engineering thermoplastic widely used in industrial water infrastructure for UV resistance, chemical compatibility, freeze-thaw tolerance, and NSF-61 potable water certification.
HDPE (high-density polyethylene) is the polymer used in modern floating cover elements. It is chosen for its long-term UV resistance, freeze-thaw tolerance, chemical compatibility with most industrial water chemistries, and the availability of NSF-61 certified grades for potable water applications. HDPE is recyclable at end-of-life through standard polyethylene recovery streams, supporting circular-economy reporting for ESG-disclosing operators.
In the AWTT-patented hexagonal cover (see /heritage), HDPE is moulded into self-ballasting hexagonal elements with a raised central dome — a geometry validated through hurricane testing and 18+ years of field deployment.
