More Information
Summary:A diaphragm and a bladder for an accumulator each include a thermoplastic film formed in a dome or bulbous shape. A metallic vapor deposition layer is disposed on at least one side of the thermoplastic. Inner and outer rubber layers are adhered on opposite sides of the metallic coated film so that the metallized thermoplastic film provides a barrier film to effectively slow the permeation of a gas such as nitrogen through the diaphragm or bladder.
