Introduction of Rubber Fender

Rubber fender, also known as rubber apron, is installed on wharf or ship to absorb collision energy between ships and wharfs or ships when they are on shore or mooring, so as to protect ships and wharfs from damage. Generally, the rubber fender can be divided into two categories according to the structure: solid rubber fender (non floating) and floating rubber fender.

Solid rubber fender (non floating type) is an early application and wide application of the dock ship anti collision equipment. According to the force condition of rubber fender, it can be divided into shear type, rotating type and compression type. According to the structure of the fender, the solid rubber fender can be divided into D type, conical, drum type, fan, rectangular, cylindrical fender and so on. Floating rubber fender can float freely on the surface of the water, according to the different internal buffer medium, it can be divided into: inflatable rubber fender, filled rubber fender. The inflatable rubber fender uses compressed air as the medium, and uses the compressed air to do work to consume the collision energy.

Foam filled fender is also called solid polyurethane fender, and the internal buffer media are mainly closed cell foam materials, such as foamed EVA, foamed polyurethane and foam rubber. The floating rubber fender is a new-type fender equipment. Compared with the solid rubber fender, the floating rubber fender is mainly characterized by high compression deformation, large energy absorption, small reaction force, self floating and easy installation. It is usually applied to ship to ship, ship to wharf and other occasions; Because of its self - floating characteristics, it is particularly suitable for the installation of a wharf with a large tidal level. The filled rubber fender is especially suitable for the application in bad environment because of its advantages of maintenance free, long life and so on.
