HDPE is a thermoplastic that belongs to the polyolefin group of materials, and is commonly used as a replacement for wood in marine applications. Sometimes referred to as "plastic lumber", HDPE offers excellent impact resistance, is lightweight, has low moisture absorption, and has high tensile strength. It is also non-toxic and non-staining.
This material is great for applications such as marine surfaces and bulkheads, industrial containers, structural components, and washers.
