EPDM is a synthetic rubber which is custom moulded /specially blended for this application. The compound formulation and moulding/extruding technique are critical to ensure that the membrane maintains its physical properties over a long period of time, resists tearing, retains its shape even after years of continuous or cyclical use, produces fine bubbles, all at a minimal head pressure. Our EPDM membranes are field tested in municipal and industrial applications with excellent results. However standard EPDM is not recommended in cases where solvents, fats oils or greases, or high concentrations of metal salts are present ineffluent.
