Exposing silicone rubber to elevated temperatures, particularly under load, can paradoxically increase its thermal stability by promoting secondary crosslinking and post-curing, rather than causing degradation. This final production research insight is drawn from a 2024 study published in Materials. Using Experimental analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Instead of solely focusing on preventing high-temperature exposure, designers should evaluate the potential benefits of controlled aging processes to enhance the thermal resilience of silicone rubber products.
