PetrozTM Perfluoroelastomer (FFKM): Excels in High Pressure, Hostile Chemical Environments -30°C (-22°F) Up to 300°C (572°F)

Download Our Petroz™ FFKM Flyer

Material & Design Solutions’ (MDS) Petroz™ perfluoroelastomer (FFKM) is a superior choice for sealing in the most challenging environments. Effective at temperatures -30°C (-22°F) up to 300°C (572°F), Petroz compounds have a broad chemical resistance in aggressive chemical environments such as H2S, amine-based (high pH) corrosion inhibitors, organic solvents, and strong acids. These compounds also offer a significantly lower compression set compared to competitive products providing longevity and a more effective sealing solution.  

Petroz FFKM compounds are designed to operate and excel in high temperature, high pressure, and hostile chemical environments. In addition, Petroz 595 and Petroz 530LT have superior rapid gas decompression (RGD) resistance and have demonstrated excellent RGD resistance in laboratory (ISO 23936-2 and NORSOK M-170) testing.  

Petroz compounds are totally fluorinated and offer the ultimate chemical resistance required in downhole applications as well as in mechanical seals, pumps, and valves in a variety of industries.
