Physical properties of rubber fender materials
The quality of rubber fender raw materials directly determines the service life and later maintenance cost of the fender. Therefore, it is necessary to put forward detailed and complete technical requirements for the physical properties of rubber fender materials in the design stage to ensure the quality of rubber.
The following are the standards for the testing items of fender raw materials. Different rubber fenders have different performance requirements for rubber. Therefore, in the design stage, it should be flexibly designed according to the characteristics of the project. At the same time, perfect technical requirements should be put forward with reference to standards to ensure the performance of rubber fenders, prolong the service life of rubber fenders and reduce maintenance costs.
