Initial Internal Pressure Pneumatic Rubber FendersDoowin-Marine pneumatic rubber fenders are manufactured and tested comply with ISO 17357. Our real Yokohama type pneumatic fenders are made by mould based on Korean production technology. Pneumatic rubber fender is consist of an out rubber, reinforcement synthetic-tire-cord layer, and inner rubber vulcanized firmly. These several synthetic-cord layers and tough abrasion resistant out rubber have consistent performance even under rough condition and cyclic load. The maintenance cost and damage risk are minimized too. The best material also ensure...

Foam Filled Fenders Donut Foam Filled Fenders Foam filled fender is the tough heavy-duty, and unsinkable floating fenders system used for the harbor, offshore and ship-to-ship operation. Netted foam fenders are designed with the chain and tire net. Netless foam fenders are without net protection. Features and Advantages ■ Unsinkable foam core - 100% closed cell foam, even the skin was punctured, it also in unsinkable without absorbing water. ■ High energy absorption, low reaction force - We have various density foam core. It has higher performance than pneumatic fenders and other rubber fenders...
