Transparent Marine Glazing Plastics from Interstate Plastics

Makrolon® marine polycarbonate plastics are flexible and made for extreme conditions in marine applications. Marine polycarbonate provides incredible durability and long-lasting optical clarity with a meticulous manufacturing process that produces low optical distortion flexible thin sheet. Advanced hard-coat technology produces exceptional abrasion resistance (we recommend Makrolon® Marine 5 for extreme resistance) and enhanced clarity and resistance to harsh chemicals. Marine grade polycarbonate is the perfect alternative to clear vinyl. Makrolon® marine polycarbonate plastics are easy to sew and cut over thicker gauge polycarbonate, great for when space is limited, and can be used for both flat and curved applications with dual sides of the sheet featuring weatherability and yellowing resistance.

Marine Board, King Starboard®, HDPE Marine Plastics

Boat Walkways, Cabinets, Counter tops, Hatches, Cover Rails & Marine Trim

Marine high density polyethylene (HDPE) plastics including lightweight and extremely tough King Starboard®, provide a flat environmentally stabilized sheet that is able to storm the harshest weather conditions and stand up to any marine environment.

Endless Boat Applications
High sliding resistance alongside excellent long-term durability make marine HDPE ideal for a variety of applications on boats including replacing wood, metal or laminate walkways, hatches, walkways, cabinets and counter tops as well as ship and boat components regularly exposed to harsh outdoor environments.

Textured Surfaces Available
King StarBoard®?has a decorative, textured surface that does not show wear, dirt or scratches.

Salt Water and Moisture Resistances
HDPE marine plastics are lightweight extremely tough, and chemically resistant. It does not absorb water and has a good sliding abrasion and unlike many other marine-based materials, our top of the line King StarBoard®?is environmentally stabilized to resist salt water, and will not rot or degrade.

Utility Grade HDPE, HDPE XL, Lightweight Marine Board, King Starlite®

Utility Grade HDPE, HDPE XL, Lightweight Marine Board, King Starlite®

Utility and XL marine grade high density polyethylene (HDPE) plastics offer a lightweight and economical alternative to our standard grades of Marine Board, by incorporating a nonabsorbent closed small cell structured core versus a solid core. This alternative grade of marine HDPE is perfect for when the material's cut edges won't be visible and other "behind-the-scenes" applications. Utility grade marine HDPE is up to 35% lighter than a solid core HDPE and it offers the same quality textured surface on both sides. Our lightweight marine HDPE is specially formulated to withstand the rigors of harsh outdoor marine environments and is UV-stabilized to resist damage and retain its beauty, even after years of direct sunlight.

Utility grade?marine board features an economical HDPE regrind which may expose visual imperfections on the surface of the sheet. For this reason, utility grade marine HDPE is commonly used where it will not be seen; for example, for marine seating that will be covered in cushion material.

Utility XL grade?marine board uses the same cell structure core as utility grade, but is made from virgin HDPE for a clean finish for exposed surfaces.

Expanded PVC, Foamed PVC, Marine PVC

Non-Load Bearing Wood & Trim Replacement, Boat Seats, Instrument Panels, Consoles, Shutters

Expanded PVC, Foamed PVC, Marine PVC

Expanded PVC is a lightweight "foamed" marine plastic able to withstand moisture, resist rot and warpage, and delamination that often occurs with wood. Marine PVC is easy to fabricate with traditional woodworking tools, and extremely versatile for ease of forming, cutting, gluing, screwing, nailing, and even stapling. Although lightweight, expanded or "foamed" PVC has an incredibly high strength-to-weight ratio that won't swell, peel or deform over time, but should not be used for load-bearing applications. Marine PVC is perfect for wood trim replacement, instrument panels and consoles, and even as an economical alternative to cabinets.

ColorCore® Versatile Marine & Outdoor Signage HDPE

ColorCore® Versatile Marine & Outdoor Signage HDPE

ColorCore® offers the same great features as our marine HDPE but has a separate color core that can be exposed through engraving or cutting. ColorCore® is environmentally and UV stabilized to withstand even the harshest outdoor marine conditions and can be used in areas that are washed often or regularly exposed to moisture. HDPE ColorCore® can be fabricated using common woodworking tools and techniques. ColorCore® is available in several gauges and a rainbow of matched colors. If you do not see the color pair you want, give us a call to find out about custom runs!
