MARINE FENDERS

Product catalog summary

Overview

Resinex marine fenders are foam-filled, closed-cell polyethylene (PE) fenders designed as a superior alternative to traditional pneumatic and rubber fenders. They provide high energy absorption with low reaction force, ensuring vessel hull protection during berthing and ship-to-ship transfers.

Product Description and Advantages

Made entirely of closed-cell elastic expanded polyethylene foam, guaranteeing unsinkability even if damaged.
High elasticity of expanded PE allows absorption of high impact energy with minimal reaction force, reducing hull damage risk.
Special expanded PE compound developed for excellent adhesion with polyurethane elastomer coating.
Steel core wrapped with expanded PE and covered by a thick elastomer polyurethane layer for abrasion and break resistance.
Available in various sizes and shapes, including angular forms, from small fenders (~0.6 m length) up to jumbo sizes (7 m length, 3.5 m diameter).

Technical Specifications

Materials

Closed Cell Polyethylene Foam: Density 33-45 kg/m³, tensile strength 4-5 kg/cm², elongation at break 130-170%, compression resistance at 30% and 50%, minimal water absorption, tested per ASTM and DIN standards.
Polyurethane Elastomer Coating: Hardness 70-84 Shore A, tensile strength 7-30 MPa, elongation at break 500-750%, excellent abrasion resistance.
Steel Core: Galvanized steel (Fe42 B/52B UNI 7070 or Fe45.2/52.2 UNI 663.68), sandblasted and coated for corrosion resistance.

Operating Conditions

Working temperature range: -20°C to +70°C
Excellent water, hydrocarbon, and UV resistance
Color: Orange

Performance Data

Compression tests on 4’ x 7.4’ Resinex fenders demonstrated the ability to withstand up to 80% compression without damage and nearly complete dimensional recovery within 2 minutes.

Energy Absorption and Reaction Force Comparison

Compared to pneumatic fenders, Resinex fenders offer high energy absorption with significantly lower reaction forces at various compression levels (50% and 60%). For example, a 4’ x 7.4’ fender absorbs 19 ton-meters of energy at 50% compression with a reaction force of 28 tons, outperforming pneumatic counterparts.
