Polymer withstands aggressive environments

Offshore staff

ABERDEEN, UK -- Aberdeen O-Rings and Seals is unveiling a new explosive, decompression-resistant perfluoroelastomer at Offshore Europe, suitable for seals in aggressive, downhole, and processing applications.

Perlast G92E is designed specifically for offshore oil and gas applications. The polymer's high fluorine content is claimed to render it inert to a wide range of liquids and gases, such as hydrogen sulfide and methane, encountered during oil and gas operations.

G92E, which is suitable for environments up to 260° C (500° F), has tested successfully in a range of high temperature, high pressure and aggressive gas conditions, including those described in NORSOK M710. Currently it is undergoing further industry and international explosive decompression standards testing.

The new product is part of the EnDura range of elastomers, including HNBR, TFE/P, and FKM products, claimed to offer better chemical resistance than conventional explosive decompression grades. EnDura seals are suitable for applications such as sub-surface valves and pumps, compressors, and drill heads.
