The Rubber Bonding Process

Rubber to metal bonding is a generic phrase covering a number of interdependent processes. The rubber bonded units that result from the process are used for the isolation of noise and vibration in automotive, engineering and chemical industry applications, such as in rubber lining of process equipment. 

Several years ago the subject was regarded as a black art . Now the technology allows the production of a uniform, high quality product that is free from failure. Much of the science behind the technology remains cloaked in uncertainty, but it is sure to become an important part of future developments. Today, environmental concerns have an impact on all aspects of commerce. Rubber-to-metal bonding is no exception, so the process is changing to reflect these concerns. 

Chlorinated rubber is also an effective bonding agent. It can be used for bonding neoprene, nitrile and natural rubbers to metals. Phenol formaldehyde resins have been used alone or in conjunction with chlorinated rubbers, but curing time is lengthy.
