EPDM Material Aging and Degradation
The operational duration of Ethylene Propylene Diene Monomer material is significantly impacted read more by ambient influences and ongoing processes leading to aging and degradation. Exposure to ozone, ultraviolet radiation, heat, and reactive chemicals contribute to the breakdown of the polymer chains. This causes a diminishment in performance metrics, such as pulling power, resilience, and overall durability. Ozone splitting, a particularly common form of degradation, occurs due to the chemical response between ozone and the double bonds present in the diene portion. Proper compounding including antioxidants and UV stabilizers can mitigate these effects and prolong the useful period of the material. Furthermore, adequate processing and handling procedures are critical to minimize premature deterioration.
