Floating Pneumatic Rubber Fenders Requirements
Construction features
Floating pneumatic rubber fenders shall consist of an out rubber, reinforcement synthetic-tyre-cord layer, and inner rubber, vulcanized firmly.
The out rubber are used to protect the cord layers and inner rubber from abrasion and other external forces. This rubber compound have sufficient tensile and tear resistance strength to withstand anticipated weather conditions and severe usage.
The reinforcement synthetic-tyre-cord layer strong enough to maintain the internal air pressure of the fender
The inner rubber layer seals the pressurized air inside the fender
Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally.
The properties requirements of outer and inner rubber material of floating pneumatic rubber fenders comply with ISO 17357:2002.
