Chemraz? 526

RGD, also known as explosive de- compression, is a phenomenon that often occurs when high-pressure gas molecules migrate into an elastomer at a compressed state. When the pressure surrounding the elastomer is suddenly released, the compressed gas inside the elastomer tries to expand and exit the elastomer, thus causing RGD. Most elastomers expe- rience severe blistering or cracking when the forces of these expanding gases overcome the strength of the surrounding material. However, Chemraz 526? offers superior RGD properties and the broadest chemical compatibility, e.g., better resistance to sour gas, acids, caustics, hot water, and steam.

Chemraz® 526
Rapid Gas Decompression Resistant

Greene Tweed’s Chemraz® 526, a perfluoroelastomer, offers superior chemical compatibility and high-temperature performance, coupled with rapid gas decompres-sion (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.
