Sometimes called marine board, HDPE plastic is petroleum-based and suitable for a myriad of applications where impact resistance and low moisture absorption are critical to structural integrity. This easily moldable material has a staggering list of usages from medical to nautical.
Commonly used as an alternative to wood in harsh environments.
HDPE (High-Density Polyethylene) is a thermoplastic that belongs to the polyolefin group of materials and is commonly used as a replacement for wood in marine applications. Sometimes you’ll hear it referred to as “plastic lumber” because of its excellent impact resistance, low moisture absorption, and high tensile strength.
This material is lightweight but tough, making it great for applications such as marine surfaces and bulkheads, industrial containers, structural components, and washers. And if that wasn’t enough, it’s especially useful in marine applications because of its non-toxic and non-staining nature.
HDPE boards are long-lasting, low maintenance, and safe, making them a healthy addition to your project. Resistant to molds, mildew, and other forms of rot, this material is uniquely suited for conditions where water transport or exposure are major factors. It’s able to be effectively sterilized and as such is used in many food and beverage applications. Wildly enough, this petroleum-based plastic is even used in reconstructive surgeries.
Water isn’t the only liquid this material is compatible with. HDPE is a great choice for use with most common chemicals, solvents, acids, detergents, and cleaning fluids. And if you’re still not sold, it’s easily recycled, has an amazing strength to density ratio, and has extreme corrosion resistance.
