Coated Fabrics for Diaphragms

Many diaphragm applications require that the rolling diaphragms be coated with rubber on both sides, commonly referred to as "double-coat" diaphragms. This type of rolling diaphragm is typically required when the application sees pressure on both sides of the diaphragm in two ways:

First, we utilize our proprietary double-coat molding process, we are able to provide double-coat diaphragms directly from rubber and fabric.

Second, we develop and maintain an inventory of standard "coated-fabrics", that is, fabric that is coated on both sides by a sub-contractor using a variety of materials. The selection of the proper double-coat process and materials requires an understanding of both the rubber and fabric used in its fabrication as well as the overall geometry of the rolling diaphragm. DiaCom technical personnel are available to assist in the proper selection of coated fabric.
