E 25 Cork and Co-Polymer cork/rubber blend is a fine cork grain; medium grade nitrile blend. Applications: Dust Seals, Mirror & Lens Cushioning Materials, Natural Gas Meters, . Meets Specifications: ASTM F104 F226000 M2 T MIL-G-12803C P2245A. Competitive grades: NC49, NC-49, NC 49, SC904R, SC-904R, SC 904R. Cork-rubber blends have a proven history in automotive, hydraulic, gas meter and various other sealing environments. Providing cost effective final product customization and manufacturing options for soft gasket sealing. Reduced side flow, allow for larger contact areas and higher compression ratios which guarantee an effective sealing barrier against potential flange surface imperfections, distortions and leakage paths, also known as material conformability. Chemical resistance is a hallmark of cork/rubber materials as they protect highly effectively against fuel, lubricants and coolants, and any other petroleum-based fluids.
