Dynamic Flex Fatigue

Dynamic flex fatigue is perhaps the most complex potential mode of failure for rubber materials, and consequently one of the most challenging to address in the design and development of rubber components. In its simplest form, flex fatigue is the cracking of a rubber component due to cyclical stresses and strains. It typically starts off as micro-cracking virtually at the molecular level, and with successive cycling, it propagates into macro-cracking that ultimately results in product failure.

Solving challenging component applications that suffer from dynamic flex fatigue is what we do at Robinson Rubber – – it’s our “sweet spot”. With our expertise, we have improved product applications across all polymer families, and we can develop an optimal formulation to meet your application needs. It is not unusual for our rubber formulations to provide useful product lives that are multiples longer than the competition’s (3X to 12X). And our manufacturing excellence ensures that we deliver this advantage for our customers in every shipment.

For decades now we have dramatically stepped up critical component performance for 3M Co., Cummins, Ecolab, Toro, and many, many others. Let us help you with your challenging components!
