Fabrics

A key component of rolling diaphragms is the fabric reinforcement selected to ensure the diaphragm will withstand the application pressure and cycle life expectations. DiaCom has developed a comprehensive selection of standard fabric styles, each with specific physical characateristics, that are selected based on weave patterns, tensile strength, formability and chemical and heat resistance capabilities, as well as other variables. DiaCom technical personnel are available to assist in selecting the proper fabric for a specific application.
