EPDM Material Aging and Degradation
The longevity of Ethylene Propylene Diene Monomer compound is significantly impacted by environmental factors and gradual changes leading to aging and degradation. Contact with ozone, ultraviolet spectrum, heat, and oxygen contribute to the breakdown of the polymer chains. This causes a diminishment in performance metrics, such as pulling power, elasticity, and robustness. Ozone splitting, a particularly prevalent form of degradation, occurs due to the chemical reaction between ozone and the double bonds present in the diene portion. Proper mixing including antioxidants and UV protectants can mitigate these effects and extend the useful lifetime of the material. Furthermore, sufficient processing and keeping practices are necessary to minimize premature breakdown.
