Rubber diaphragms are flexible rubber membranes, sometimes reinforced with fabric, strategically placed to prevent unwanted transfer of substances between two places by creating a seal. They can be used to separate two gasses, two liquids, or one gas and one liquid that should not mix.

Diaphragms can be made of a wide variety of rubber materials, depending on final application. Read on to learn more about the benefits of rubber diaphragms and when you should use one in place of a gasket or traditional seal.

Productive Process

Diaphragms made only of rubber are called homogeneous rubber diaphragms. In this case, the diaphragms are typically compression molded because they’re so thin. It’s difficult to make a thin, flexible membrane through injection molding or transfer molding.
