Bestfluor\u00ae 4075 is a new high-chemical-resistance perfluoroelastomer (FFKM)<\/strong> from Solvay. It provides exceptional resistance to a broad range of aggressive media and excellent compression set performance. Featuring high purity, extrusion resistance and rapid gas decompression (RGD\/ED) resistance, it can be processed by conventional fluoroelastomer methods and supplied as raw gum.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
