Product Description

Our non reinforced EPDM diaphragm sheeting is a high-grade, highly versatile material that offers excellent resistance to weather and Ozone deterioration. With superior physical properties such as; tensile strength and elongation break points. Our non reinforced diaphragm sheeting offers consistent performance for use in a wide range of diaphragm applications. We can supply this product in a variety of formats as standard; either in full rolls, strip cut lengths or cut to bespoke gaskets and shapes. This particular material is available in either 0.5mm or 0.75mm thick sheets as standard.

The combination of good physical properties with water and weathering resistance help to create a strong but flexible material. Many of our customers use our EPDM diaphragm sheeting to transmit pulsating motions between a range of fluids, gases as well as air in almost all types of guages, meters and valves.
