| Bestfluor® 4075 is a new high-chemical-resistance perfluoroelastomer (FFKM) 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. | ||
