What Factors Cause Aging Of The Rubber Fender?

The rubber fender is the main part of rubber materials, so the aging of products is the root cause of rubber fender problems. The main reasons for aging of the rubber fender are as follows:
Firstly, in the process of protecting the ship, under the action of reaction force, the rubber molecular chain will break free of the bow and oxidize.
Secondly, the thermal effect is an important reason for accelerating the aging of rubber. The increase of temperature will lead to thermal cracking or thermal cross linking of rubber. At the same time, it also has a strong activation effect to improve the speed of oxidation and diffusion, so the rubber appears thermal aging.
Thirdly, it is the role of ozone. The chemical activity of ozone is much higher than that of oxygen, and the damage is also greater.
Fourthly, it is the oil. In the course of use, if the rubber fender and oil contact for a long time will make oil into the rubber and react with it, which will change the network structure of  the cross-linked rubber, resulting in the oxidation of rubber.
After understanding the oxidation factors of rubber, we can carry out certain maintenance of rubber fender from the above aspects.
