Rubber-to-metal bonded assemblies consist of an elastomer that is molded and chemically bonded to a clean metal surface using a specialized adhesive. During the injection, transfer, or compression molding process, rubber vulcanization and adhesive curing occur at the same time. Applications include small vibration mounts and massive railcar suspension components that weigh over 200 lbs.…

Durometer is a measure of a rubber’s resistance to indentation. More commonly, however, it’s known as a measure of hardness. Modulus, another material property, is the stress or force that’s required to produce a strain. Higher-durometer rubber usually has a higher modulus, but that doesn’t mean the relationship between durometer and modulus is straightforward –…
