Northeast Plastics



For centuries, the marine industry has been a cornerstone of human civilization. It has provided us with a means to explore, trade, and connect with different parts of the world. However, innovation never ceases, and the latest revolution in marine technology comes from a seemingly unlikely source: plastics. 

Far from being just a household material, plastics have proven to be a game-changer in marine applications. This article delves into the numerous advantages that plastics bring to the table and explores their versatile applications in the marine sector.

Durability Against the Elements

One of the most significant challenges in marine applications is the corrosive and deteriorating impact of saltwater, UV rays, and chemicals. Traditional materials like wood and metal are susceptible to rot, corrosion, and warping. In contrast, plastics are resistant to saltwater, UV, chemicals, and corrosion, making them a long-lasting solution for the marine environment.

Stability and Rigidity

Plastics offer a combination of stability and rigidity that is hard to match. They maintain their shape and do not warp or delaminate, ensuring that components made from plastics are reliable and long-lasting.

Hydrodynamic Efficiency

The low coefficient of thermal expansion in plastics results in minimal changes in shape and size with temperature fluctuations. This property enhances the hydrodynamics of marine vessels, allowing them to move smoothly through water.

A Closer Look at Marine-Grade Plastics

Material Types

  • Acrylic (PMMA): Known for its optical clarity and weather resistance.
  • Acrylic-Styrene-Acrylonitrile (ASA): Offers excellent UV resistance.
  • High-Density Polyethylene (HDPE): Known for its high strength-to-density ratio.
  • Nylon/Cast Nylon (PA): Exceptional wear resistance.
  • Polyvinyl Chloride (PVC): Highly versatile and easy to fabricate.


Advanced fabrication methods have allowed for a wide range of possibilities:

  • CNC Routing: For precise cuts and close tolerances.
  • Laser Cutting and Polishing: For a finished look and feel.
  • Heat Bending: Allows for complex, sculpted contours.
  • Applications Beyond Supply
  • Nautical Necessities
  • Fuel Lines: Highly resistant to corrosive elements.
  • Cowls and Fairings: For aerodynamic efficiency.
  • Fishing Rod Holders and Racks: Lightweight and durable.
  • Safety Measures
  • Boat and Dock Bumpers: Absorbs impact, preventing damage.
  • Pulleys and Sheaves: For efficient load distribution.
  • Interior and Comfort
  • Cabinetry: Aesthetically pleasing and easy to clean.
  • Swim Platforms: Slip-resistant and durable.

Sustainability and Environmental Concerns

It's crucial to address the environmental impact of using plastics. Companies are increasingly investing in biodegradable and recyclable plastics to mitigate their ecological footprint.


Plastics have proven to be more than just a convenient material; they are an essential part of modern marine applications. Their versatility, durability, and ease of fabrication make them a superior choice for everything from fuel lines to swim platforms. In an industry that demands the most robust materials, plastics not only meet the criteria but often exceed them, shaping the future of marine technology.
