Pneumatic fender is a leading anti-collision device for marine application in the world today. This fender is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a protective medium. Therefore, pneumatic rubber fenders serves as a critical protective medium against collision when ship-to-ship (STS) transfer operations and ship-to-dock (STD) berthing and mooring operations.
Pneumatic fenders have the advantages of massive energy absorption with low unit surface pressure acted upon the ship. So pneumatic fender has become an ideal ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, bulk carriers and floating structures, large docks, harbor and wharfs.

Floating pneumatic rubber fenders, whose basic body construction consists of outer rubber layers, synthetic-cord-reinforced rubber layers and inner rubber layers, are kind of cylindrical air bags with hemispherical heads at both ends.
The outer rubber layer that covers the outside of fender protects the cord layers and the inner rubber from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black, but other colors such as grey and creamy white are available on request.
The liner of a rubber membrane seals the pressurized air insider the fenders.
The reinforcement cord layers, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
Synthetic-tire-cord layers, commonly used in tires, have been proven to provide strong efficient reinforcement layers in fenders; each single layer is coated with rubber compound on both sides as well as in between synthetic-tire-cord threads, hence isolating all cords from each other.
As contact between synthetic-tire-cord threads does not occur, synthetic tire cord has the advantage over other reinforcement materials such as canvas fabric of reducing friction and wears between cord threads during compression, bending and stretching, and also greatly improves fatigue resistance, endurance life, and pressure-holding performance.
