EPDM rubber granules are widely used in many industries. When using them, we should also pay attention to proper maintenance and care depending on the environment, as neglecting this can lead to aging. What are the factors that can affect its aging?

Oxygen reacts with rubber molecules through free radical chain reactions, causing the molecular chains to break or over-crosslink, thereby altering the rubber's properties. Oxidation is one of the primary causes of rubber aging. Ozone, with its higher chemical reactivity, is more destructive. It also causes molecular chain breakage, but its effect on rubber varies depending on whether the rubber is deformed. When acting on deformed rubber, it only forms an oxidized film on the surface without cracking. Increasing temperature can lead to rubber thermal cracking or thermal crosslinking. However, the fundamental role of heat is to activate. Increasing the rate of oxygen diffusion and the activation of oxidation reactions accelerates the rate of rubber oxidation.

Certainly, when using it, we should also pay attention to performing appropriate maintenance and care based on different usage environments to avoid environmental impact that could reduce its lifespan and effectiveness. This ensures better performance.
