Chemraz® 526

Chemical Processing, Energy, Industrial Operations

Greene Tweed’s Chemraz® 526, a perfluoroelastomer, offers superior chemical compatibility and high-temperature performance, coupled with rapid gas decompression (RGD) (also known as explosive decompression) resistance, making it the ideal compound for hostile oilfield environments in downhole and surface equipment. Chemraz® 526 has a temperature range from -4°F to 482°F (-20°C to 250°C). With its outstanding RGD-resistant capabilities, Chemraz® 526 is well suited in a range of applications, from drilling tools, wireline tools, and completion equipment to pumps and valves. Chemraz® 526 is available for use as o-rings, gaskets, and many other custom shapes.
