Elastomeric Diaphragm Seals

February 7, 2016

The DiaCom Proprietary Double-coat process has been developed so the elastomer is not “formed” from calendared sheet stock but is molded from an equal amount of unvulcanized elastomer on each side of the fabric. This eliminates dimensional instability and ensures that the fabric is constantly oriented near the center of the part, which has traditionally been problematic with double coat diaphragms produced from calendared material.
