What Are Marine Fenders?

Marine Fender, also called ship fender, is an elastic cushioning equipment widely used at Ship's or Boat's edge/shipside and at wharf/pier/dock/hoverport/jetty/pontoon, it  is mainly used to reduce the impact force between ships and docks while docking or mooring. In other words, marine fenders can be simply termed as '' Marine Bumpers ''.

I. High performance Pneumatic Rubber Fender

Pneumatic rubber fender is the advanced anti-collision device for marine application the world today, use compressed air as medium to absorb the impact energy when ship to ship contact(STS) and ship to berthing(STB). Comparing with tradintional bumper style rubber fender, it has the following advantages: more energy absorbtion, less reverse impact on ships, less weight, easy installation, softer and economical, etc. So, pneumatic rubber fenders are widely used by large tankers, PG vessels, ocean platforms, large docks, harbor and wharves.

Manufacture Process of Pneumatic Rubber Fender
1. Raw material
2. Produce the fender
3. Vulcanizing
6. Make the tyre nets
7. Testing and Gasing
8. Pacing and Delivery

II. EVA Foam Filled Fender

EVA foam filled fender is a new kind of synthetic polymer whose performance has both advantages of plastic and rubber, the high strength of plastic and good elasticity of rubber. The characteristics are: High wear resistance , excellent oil resistance, high mechanical strength, Its tensile intension and tear strength and burden capability are high. Excellent tolerance of acid, alkali, low temperance and organic solvent. High mental-bonding performance, wide hardness range. The main character is the function of floating, not affected by the tide. All colours can be made. Solid but light, easy to move and install/operate. The react force is dramatic when compressed 60%, and high absorbing energy.

III. PVC Yacht Fender

Pneumatic/Inflatable yacht fender is a kind of marine supply that can protect the yacht from the harm of berthing. Recently, as the development of yacht industry, this kind of fender is widely used in yacht, speed boat, dock and floating platform etc. It is sealed container that made of high quality PVC raw material. The product can float on the water surface after it is filled with compressed air. It is an important cushion as between yacht and yacht, yacht and berth. At the same time, pneumatic yacht fender can absorb a lot of impact energy of the movement of the ship, it can also reduce the recoil force of the ship to greatly improve the safety of yacht berthing.
