Ocean Dolphin

Rubber Coating Foam Fender

NANHAI is the exclusive manufacturer of  Ocean Dolphin (Rubber Coating Foam Fender) which replaced the traditional polyurethane foam fender. This type fender has high elasticity and quick recovery, meanwhile has a softer effect on the hull widely used in navy berths.

Ocean Dolphin uses the laminated polyethylene foam core inside and with thick long nylon filament reinforced layer. Outer skin (usual is grey) uses high performance rubber layer and proceed to overall vulcanization. The rubber layer is highly integrated with foam core, tear strength is greatly increased. Due to its excellent performance, it is widely used in navy berths.

NANHAI Ocean Dolphin 2

Ocean Dolphin can reflect high application performance, mainly due to the outer rubber skin instead of Polyurethane skin. This is the physical advantage of rubber, and NANHAI takes it to the extreme.

  • 01-High Performance Rubber Skin
  • 02-Closed Cell Foam Core (100%)
  • 03-Nylon Filament Reinforcement Layer
  • 04-Heavy Duty Internal Structure
  • 05-Heavy Duty End Fittings

01 High Perfoamnce Rubber Skin

Due to the physical properties of rubber materials, compared with polyurethane skin, rubber skin is more elastic, quickly recovery. More gentle to the hull.

02 Closed Cell Foam Core (100%)

Due to the molecular structure of Closed Cell (Isolation of Gas), so the foam core can maintain excellent elasticity which is the basis of foam fender performance. Ocean Dolphin utilizing only cross-linked, closed cell polyethylene.

03 Nylon Filament Reinforcement

Ocean Dolphin is constructed Continuous Tough and Thick Nylon Filament Reinforcement during rubber skin coating which provides superior strength.

04 Heavy Duty Internal Structure

Heavy Duty Chain Connecting Swivel End Fitting Type (The internal chain guarantees maximum pull-through strength, even distribution of energy and stresses.) and Heavy Duty Internal Pipe Fixed End Fitting Type optional. All fittings are constructed of top-quality steel.

05 Heavy Duty End Fittings

Heavy duty fittings include swivel ring, shackles, flanges are all hot dip galvanized to ensure corrosion resistance and high strength.
