Pneumatic rubber fender consists of an outer rubber, reinforcement synthetic-tyre-cord layer, and inner rubber, vulcanized together firmly.
1. The outer rubbers 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.
2. The reinforcement synthetic-tyre-cord layer strong enough to maintain the internal air pressure of the fender.
3. The inner rubber layer seals the pressurized air inside the fender.
4. Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally.
