# Marine-grade polymer

Marine-grade polymer is a plastic cabinet material made to handle constant moisture, sun and salt without rotting, swelling or needing a new finish.

Marine-grade polymer is a name for plastics used in boats and docks. The material resists water, UV light and salt. It does not rot. The term is a trade description, not a formal standard, so check what the plastic is.

The most common cabinet version is [HDPE](https://innovationcabinetry.multisites.ai/glossary/hdpe). Outdoor kitchens use it because wood and wood-based boards can swell and peel outside.

Innovation Cabinetry's Endura brochure calls its material "3/4" marine-grade, all-weather high-density polyethylene (HDPE)." The Endura datasheet says it "meets ASTM D4976." It also says Endura "contains no VOC's." Look at [Endura](https://innovationcabinetry.multisites.ai/endura) and the [outdoor kitchen cabinets](https://innovationcabinetry.multisites.ai/outdoor-kitchen-cabinets) page for door styles. The [materials guide](https://innovationcabinetry.multisites.ai/guides/outdoor-kitchen-cabinet-materials) compares options. See [stainless steel](https://innovationcabinetry.multisites.ai/glossary/stainless-steel) for hardware. Ask your dealer for a sample so you can handle the material before you choose.
