ABSTRACT OF THE DISCLOSURE A floating rubber fender to be used for ships, plat- forms, locks, or the like. In order to provide a fender which will not sink when its support cables break, it has been propo- sed to manufacture the fenders partly of massive rubber, with the remainder thereof comprising sponge or foam rubber, such that the overall density is less than 1.0 and is therefore of floating construction. However, such fenders are not suitable for the heavy conditions of use to which they are subjected since the use of foam rubber or sponge results in decreased rigidity and tear resistance. To overcome this problem, the present invention provides a floating rubber fender consisting of a rubber body manufactured from massive rubber, the rubber body having been manufactured from a substantially synthetic rubber having a density below about 0.91. Additionally, a carbon black is utilized as a reinforcing filler, the carbon black promoting electrical conductivity and having a small particle size and a high structure. The carbon black is added in such an amount that the density of the rubber after vulcanization amounts to at most 0.97.
