Solid rubber fender (non-floated type) is a historic and widely-used collision protection device for docked ships. It can be categorized into shear-type, rotational-type, and compression-type based on the load-bearing conditions of the fender. According to the structure of the fender, solid rubber fenders can further be divided into D-type, cone-shaped, drum-shaped, fan-shaped, rectangular, cylindrical fenders, and so on.
Floating rubber fender can freely float on the water surface and is categorized into: inflatable rubber fender and filled rubber fender based on the different internal buffer medium.
The inflatable rubber fender utilizes compressed air as a medium, dissipating collision energy through the work done by the compressed air.
Foam-filled fender, also known as solid polyurethane fender, is internally filled with a cushioning medium primarily composed of closed-cell foam materials, such as foam EVA, foam polyurethane, and foam rubber, etc.
