Custom Marine Polyurethane Parts for Ships and Equipment
PSI Urethanes manufactures custom marine polyurethane parts for commercial marine, offshore, and maritime applications where durability and long-term performance are critical. Our custom marine urethane parts are engineered to withstand hydrolysis, microbial attack, saltwater exposure, and demanding operating conditions, including low ocean temperatures and high-pressure deep-water environments.
From protecting pipes and cables to encapsulating electrical components and reducing strain on critical systems, our polyurethane marine components provide outstanding flexibility, abrasion resistance, and impact protection. Whether you need marine urethane rollers, protective covers, or fully custom molded components, PSI Urethanes delivers solutions tailored to your exact performance requirements.
Advantages of Using Urethane for Marine Applications
Cast polyurethane offers a combination of properties that make it well suited to marine and maritime use:
- No Water Absorption
- Salt Water Resistant
- UV stabilized (when the color black or red is used)
- Resists the growth of algae and fungus
- Can be placed in humid or tropical locations
- Does not oxidize even after long exposure to water and harsh environment
- High load-bearing properties
- Great vibration and shock absorbing properties
- Low noise
- High abrasion resistance
Ship & Equipment Types Benefiting From Cast Urethane Parts
PSI Urethanes manufactures marine polyurethane parts for a wide range of vessels, offshore equipment, and marine infrastructure. Our custom marine urethane parts are engineered to withstand constant exposure to water, heavy loads, impact, abrasion, and harsh operating environments while delivering long service life.
Our polyurethane marine components are commonly used on:
- Motor & Sail Yachts: Rollers, bumpers, wear pads, and protective components that help reduce wear while improving docking, launching, and onboard equipment performance.
- Commercial Fishing Vessels: Durable components designed to withstand continuous operation, saltwater exposure, and demanding deck equipment applications.
- US Navy Ships: Custom polyurethane components manufactured for demanding marine environments where durability, vibration reduction, and long-term reliability are essential.
- US Coast Guard Vessels: Wear-resistant parts used throughout mission-critical equipment and marine handling systems.
- Offshore Construction & Oil and Gas Equipment: Heavy-duty polyurethane components for cable protection, lifting systems, subsea equipment, and offshore infrastructure.
- Boat Trailers & Boat Lifts: Marine urethane rollers, V-rollers, roller cradles, and guide components that protect hulls while providing smooth launching and retrieval.
- Ports, Marinas & Dock Systems: Dock bumpers, protective pads, rollers, and custom components built to withstand repeated impacts and continuous weather exposure.
- Wastewater & Water Treatment Facilities: Corrosion-resistant polyurethane components used in pumps, conveyors, rollers, seals, and other water-handling equipment.

FAQs
What equipment uses marine polyurethane parts?
Marine polyurethane parts are used on commercial ships, workboats, tugboats, barges, ferries, fishing vessels, offshore equipment, docks, boat lifts, trailers, winches, conveyors, and material-handling systems. Common components include rollers, wheels, bushings, bumpers, seals, wear pads, liners, and custom molded parts.
Why is polyurethane useful in marine environments?
Cast polyurethane can provide strong resistance to abrasion, impact, tearing, oils, and repeated loading while remaining more flexible than many metals and more durable than many rubber or plastic alternatives. The correct formulation should be selected for the water exposure, temperature, chemicals, and load conditions.
Can PSI replace an obsolete marine rubber or plastic part with urethane?
Yes. PSI can review a drawing, sample, or worn component and evaluate whether a custom cast urethane replacement is appropriate. Parts can be molded in different shapes, sizes, colors, and durometers, and may be bonded to metal when the application requires it.
What information is needed to quote a custom marine urethane part?
Helpful details include drawings or samples, dimensions, quantity, load, speed, operating temperature, water or chemical exposure, hardness requirements, tolerance, and whether the part needs a metal core or bonded insert.
