Elastomer Bonding – A Flexible and Robust Method for Joining Parts

When bonding with elastomers, an elastic material – often an elastomer – joins two or more parts. The elastomers can contain additives as an option to ensure electrical conductivity.  

Bonding creates a solid and durable bond that lasts even under extreme conditions. The fact that elastomers can be used on various surfaces and for different applications – from electronics to components in the automotive industry – means that the process is highly versatile.

A particular advantage of this bonding process is that it is carried out at room temperature. This prevents the occurrence of mechanical stresses in the bond after joining, which could otherwise be caused by different thermal expansion coefficients of the target and backing plate at higher temperatures. Therefore, this method suits target composites exposed to high mechanical loads. At the same time, the elastic properties of the elastomer allow a certain amount of movement between the connected parts, which is why this bonding process is also used for components exposed to vibrations or thermal fluctuations.
