Marine-Grade Plastic Materials and Applications

The marine industry relies on performance plastics that have the durability and longevity to endure an array of exterior and interior applications. Polymershapes provides access to industry-leading solutions designed to replace marine plywood, metal, laminates, and more.

Our marine plastic material is developed to withstand constant exposure to harsh environments. It is often found in hatches, cabinets, counters, and walkways, and many mechanical components. Our marine plastic material options provide UV resistance, toughness, optical clarity, weathering resistance, and more in a lightweight package.

Marine-Grade Plastic Products

Marine-Grade HDPE

Marine-grade high-density polyethylene, also known as BOATBOARD® or Starboard, is a mainstay of the industry, commonly used in instrument panels, deck and seating components, storage bins and more. Marine HDPE will not delaminate, rot, or splinter. It features an easy-to-clean surface, and integral color to reduce the appearance of scratches and marring. Specialty grades such as SIMONA’s BOATBOARD® offer extreme durability, UV and water resistance. With superior flatness and consistency from sheet to sheet, it provides easier, more efficient fabrication with less scrap and lower labor costs. BOATBOARD Lightweight is a lightweight-grade plastic, offering up to 20% weight savings when converting from standard marine-grade HDPE sheets.

Acrylic Clear Plastics and LEXAN™ Polycarbonate

Clear plastics for boat windows, windshields, and hatches are frequently fabricated from acrylic or LEXAN™ polycarbonate. The team at Polymershapes can help identify the best transparent material for your needs. Some of our options include: cast acrylic for higher chemical resistance, impact-modified acrylic for superior impact strength, or abrasion-resistant, hard-coated acrylic for increased surface hardness.

LEXAN polycarbonate is a virtually-unbreakable material that is available in a variety of textures and surface patterns. It offers impact and abrasion resistance in a lightweight sheet or film. LEXAN is a popular choice for marine enclosures, ensuring safety and durability without compromising optical clarity. Investing in LEXAN gives you a clear view of the open water for years to come.

Diab Divinycell Coring Composites

One of the most common drawbacks of thick and sturdy material is the weight that comes with it. Conventional building materials may be strong, but are typically very heavy, which can increase strain on mechanical parts, and require more energy consumption to meet demand. Coring composite plastic fixes this issue. Instead of extremely thick and heavy construction, plastic cores can be fitted inside a hollow shell of the haul. The result is a much stiffer and more rigid core, with a fraction of the weight.

Divinycell HP

If your application requires a high temperature tolerance and high peel strength, Divinycell HP is a PVC material with the dimensional stability and stiffness-to-weight ratio to address your needs.

Divinycell HM

Divinycell HM's high-performance material is developed for high-stress marine applications. Featuring extreme strength and superior elongation capabilities, HM is used to produce highly durable, lightweight marine vessels.

Divinycell PY

If you're looking for a thermoplastic with multiple applications, Divinycell PY is a PET material designed to withstand fluctuating temperatures and chemical exposure while retaining its strength and shape. PY is also recyclable, making it an environmentally friendly option.

Divinycell H

Divinycell H is developed for high-stress applications, designed to endure constant slamming, blunt force trauma, and more. It features the highest strength-to-weight ratio in its class.

Foam PVC

Foam PVC is cost-effective, weather and rot-resistant, lightweight choice for marine upholstery, and can serve as a long-lasting replacement for wood paneling. With standard and marine grades available, Foam PVC offers great insulation properties, with excellent screw and lag retention.

ABS Plastic and Recycled Plastic Material

Materials like ABS and PVC utility board can adhere to fiberglass, offering rigidity and no water absorption. Recycled plastic materials are becoming an increasingly popular sustainable choice for cleat blocks and bulkheads. Polymershapes provides a wide range of product knowledge you can rely on, and assists with selecting the best material for your application, while providing the best service and products for your marine applications.

Low-Density Polyethylene (LDPE) Tubing

Low-density polyethylene (LDPE) tubing offers significant impact and chemical resistance, making it ideal for transporting fluids, drainage, vacuum bags, and more. Boat and shipbuilders commonly use LDPE. Thermoplastic Processes Excelon also offers excellent long-term stability and corrosion resistance.

Ultra-High Molecular Weight Polyethylene (UHMW)

Ultra-High Molecular Weight Polyethylene (UHMW or UHMWPE) is an excellent choice for dock fenders, rub rails, and lift bushings. It is hailed for its superior impact resistance, wear resistance, and long-term reliability in wet and dry environments. It also offers low-friction and anti-corrosion qualities along with strength comparable to various metals, making it a great alternative for mechanical components. UHMW is a great investment that can reduce energy use, maintenance costs, and more.

Fabrication Services

Cut-to-Size Plastic Sheets

Full-size plastic sheets come prepared with enough material to meet your needs. However, you may not need it all, or it may be beneficial to receive it in smaller segments. Polymershapes can cut and size your order to ensure you are getting the right amount of material for your application.

Plastic Routing

Our network of in-house and partner facilities can finish, mill, bend, or cut your product into different shapes to ensure your order is ready-to-use upon arrival.

Benefits of Performance Plastics in the Marine Industry

Whether you are in a freshwater or saltwater setting, the life span and reliability of your equipment is heavily dependent on the quality of the material. Performance plastics are developed with long-term use in mind, and allow for an array of uses in the harshest environments. Some benefits include:

  • Lightweight
  • Saltwater, UV, weather, chemical, odor and stain resistance
  • Low coefficient of thermal expansion
  • Low moisture absorption
  • No rotting, swelling, or splintering
  • Increased hydrodynamics
  • Excellent stability and rigidity

Conventional materials may succumb to tarnish, water damage, salt damage, rust, weathering, and other forms of wear. Polymershapes performance plastics will extend the lifetime of your equipment and allow for applications in harsher environments.
