Foam Filled Fender

What is Foam Filled Fender?

Jerryborg Marine use heat laminated 100% closed cell foams for the fender core with a tough and thick nylon filament reinforced polyurethane skin, which have high compressive strengths, resulting in an ability to absorb a great deal of energy during marine operations.

Our marine floating foam filled fenders also have an unique internal structure to avoid overload and absorb the shear loads, which maks berthing operations easier and safer – especially in severe conditions.

Our foam filled fenders are available in diameters from 200 mm to 4,500 mm and lengths from 500 mm to 10,600 mm, various foam densities as well as different shapes and sizes. The floating foam fenders could be installed with a two or four point mounting system, depending on the actual installation requirement.

Advantages of Jerryborg Marine Foam Fenders

  • 1.High energy absorption and low reaction force
  • 2.Unsinkable even if the skin is damaged
  • 3.Simple and effective internal engineering strtucutre
  • 4.Easy to install and low maintenance costs
  • 5.Nylon filament reinforced polyurethane elastomer skin
  • 6.Available with chain and tyre net
  • 7.Standard range supplemented by bespoke design service

Why Choose Jerryborg Marine Foam Filled Fender ?

1. 100% Closed Cell EVA Foam

Each closed cell is completely enclosed and as they are packed tightly together, they will not compress or settle over time. Based on above advantages of clsoed cell strucure, it means EVA foam can absorb impacts without damage, and won’t crush or flatten at point of contact when berthing. Water is not able to permeate into the foam as each cell is enclosed, Even if the abrasion occurs against the polyurethane skin of a foam fender, the fender will still maintain its original shape and continue to float.

2. Polyurethane Skin

Polyurethane skin is a polyurethane coating layer applied to the surface of marine foam fender for the purpose of protecting it from various types of defects such as corrosion, weathering, abrasion and other deteriorating processes. The characteristics and properties of polyurethane coatings make them ideal for application to the foam fender skin as well as coating skin for other marine fendering and floating products.

3. Technical Reinforcement

Several kinds of reinforcement material are used in our floating foam filled fenders, such as metallic or synthetic tire cord textiles, according to building rules. These soft composites reinforcement layers can strenghten the foam fender and enhance the adhesion effect of polyurethane coating or SPUA coating.

4. Unique Designed Internal Structure

Our certified structure designing engineers can make steel structures, such as axles for fenders, frames for buoys &floats, to a required specification within our own metal fabrication factory.

Before formal production, our technical eingeer will make and analyse stress calculation, then optimize the design or structure to get better products.
