Moisture-Resistant Polyethylene (HDPE) Sheets, Bars, and Strips
Practically nonabsorbent, these sheets, bars, and strips won't swell when exposed to water. They’re harder and denser than LDPE, plus they’re more chemical resistant. They are often machined into plugs, seals, and containers.
If you don't see the size you're looking for, please specify length and width under additional sheet sizes.

Also known as pipe-grade HDPE, these sheets are about four times more impact resistant than standard HDPE and hold up outdoors, and in wet environments. While other high-impact plastics such as LDPE, UHMW, and ABS can’t be used outdoors, these sheets will not swell when exposed to water. They resist chemicals and contain carbon black, so they will not break down from UV exposure. These sheets are often used to make stub ends, gussets, end caps, flanges, tanks, and containers. Weld them using extrusion, hot gas, and speed tip welding methods and easily fabricate them with standard woodworking tools.

Recycled Marine-Grade Moisture-Resistant Polyethylene (HDPE) Sheets
- Color: Black
- Maximum Temperature: 180° F

- Impact Strength: 0.7 ft-lbs./in. (Poor)
- Hardness: Durometer 68D (Medium)
- For Use Outdoors: Yes
Made of recycled HDPE plastic, these sheets are more sustainable and economical than standard marine-grade moisture-resistant HDPE sheets. They won’t absorb moisture or swell when exposed to humidity. They also won’t degrade in salt water. However, their properties have more variance and broader ranges than material that is not recycled. Because these sheets have a low carbon footprint, they can help you meet criteria for sustainability certifications, such as LEED and Envision, or comply with company environmental initiatives.
Coarse sheets are textured to hide scuffs and scratches.
