Rubber and Synthetic Rubbers: Rubber and synthetic rubber gaskets are some of the most common materials used in gasket applications. This is due to their inherent properties as elastomers. They typically, bend, stretch, twist, flex and conform to other shapes easily. This makes them a very good options to fill up the nooks and crannies between the two uneven surfaces (flanges) we are trying to seal. Rubbers, however, can face significant limitations in certain situations where temperatures become too cold (or hot) or if it comes in contact materials that don't play well with rubber. Moreover, in some cases, if materials are too soft, creep relaxation can lead to a lack of load or force (compression) from bolts and ultimately a lack of seal.
