EPDM Material Aging and Degradation
The service life of Ethylene Propylene Diene Monomer compound is significantly impacted by exposure conditions and ongoing processes leading to aging and degradation. Contact with ozone, ultraviolet light, heat, and oxygen contribute to the breakdown of the polymer chains. This leads to a reduction in mechanical properties, such as pulling power, flexibility, and overall durability. Ozone cracking, a particularly frequent form of degradation, occurs due to the chemical response between ozone and the double bonds present in the diene portion. Proper formulation including antioxidants and UV inhibitors can mitigate these effects and increase the useful period of the material. Furthermore, adequate processing and handling procedures are critical to minimize premature deterioration.
