Jerryborg Marine Foam Filled Fender

Jerryborg Marine uses heat-sealed foam for its fender core. The foam is fully enclosed and covered with a strong, reinforced polyurethane exterior. This feature makes the fender highly resistant to stress, allowing it to absorb large amounts of energy while operating at sea.

Our foam fenders stand out for their consistency and superior quality. Available in five foam grades and both U.S. and metric standard sizes, they cater to a wide range of needs, from ultra-low hull pressures to extreme performance demands. Reinforced with Flosys 4-axis filament winding, they achieve exceptional strength and a uniform finish. The PU elastomer skin features an extra abrasion-resistant layer and is customizable in nearly any color, with black, grey, and orange as standard options. These foam-filled fenders have special insides to prevent overloading and manage docking pressure. They make mooring safer and simpler, even in rough weather.

They are available in various sizes, from 200mm to 4,500mm in diameter and 500mm to 10,600mm in length, and are designed to meet various maritime needs. They also come in different foam densities and shapes. Depending on the specific setup required, they can be installed using a two-point or four-point mounting system.

Construction Parts of Foam Filled Fenders

Construction Parts of Foam Filled Fenders

Foam Core

The energy-absorbing foam core of our foam-filled fender shall be heat-laminated. Chipped or granulated particulate foam, as well as adhesives to bond the foam together, are not acceptable. Also, our foam core is 100% closed-cell foam. Each closed cell is completely enclosed, which prevents it from compressing or settling over time.

Nylon 6 filament reinforced and polyurethane elastomer skin.

The outer skin of our foam-filled fender is constructed of elastomer with filament reinforcing as specified. The polyurethane skin is reinforced with nylon 6 for extra strength. The reinforced skin’s tensile strength can reach 31Mpa, with tear strength around 78.8kN/m. The skin is thick enough to provide enough nylon wraps. They transfer shear forces from berthing and the rated reaction force.

Polyurea Spraying Coating

The surface of our foam-filled fenders will be sprayed with polyurea. Spraying polyurea can make them tough. It makes them resist chemicals, weather, and damage. It also keeps them flexible in extreme temperatures.

Advantages of Jerryborg Marine Foam Fenders

High energy absorption and low reaction force: Our foam fenders absorb impact well. They reduce the force returned to the vessel and protect it from berthing damage. This ensures safety and reduces repair costs.

Unsinkable even if the polyurethane skin is damaged: Featuring a closed-cell foam core, our floating foam-filled fenders remain buoyant and effective even when punctured. The foam core can still provide continuous protection.

Nylon 6 filament-reinforced polyurethane elastomer skin: The polyurethane skin is reinforced with nylon 6 for extra strength. Reinforced skin has a tensile strength of 31Mpa and a tear strength of 78.8kN/m. These traits ensure durability in harsh marine environments.

Strong and effective internal engineering structure: Unlike the foam sheet rolling production method, Our proven design of foam-filled fenders ensures high durability and consistent performance.

Easy to install and low maintenance costs: Our foam-filled fenders are easy to install and need little maintenance. They save money over their lifespan by cutting downtime and repair needs.

Available with chain and tyre net: You can equip the foam fender body with an optional chain and tyre net. This adds protection, spreads stress evenly, and extends the fender’s lifespan.

Standard range complemented by customized design service: Beyond our standard range, we offer custom design services to meet specific needs. They ensure your vessels get optimal protection tailored to unique requirements.

Why Choose Jerryborg Marine Foam Filled Fender ?

1.Made with 100% Enclosed EVA Foam

This foam is built with tightly packed, fully sealed cells that don’t compress or change shape over time. The closed cell structure of EVA foam absorbs the hits well. It won’t get damaged, crushed, or lose shape easily. Since each cell is sealed, water can’t get in. So, the foam keeps its form and buoyancy, even if the outer polyurethane layer gets scratched.
