HOUSTON -- Precision Polymer Engineering (PPE) will highlight its latest explosive decompression (ED) resistant, Perlast G92E perfluoroelastomer at OTC in the Reliant Arena.

PPE says the combination of Perlast G92E's ED, temperature, and chemical resistance and PPE's seal design service allows operators to specify seals optimized for maximum operational life in ultra aggressive offshore processing applications.

The Perlast G92E elastomer can operate in environments up to 500 °F (260 °C). It has undergone successful tests in a range of high temperature, high pressure, and aggressive gas conditions, including those outlined in NORSOK M710. Currently, it is being subjected to further explosive decompression standards testing.

Perlast G92E is part of the EnDura range of elastomers designed for the offshore industry. The polymer's high fluorine content renders it inert to a wide range of liquids and gases encountered during oil and gas operations such as hydrogen sulfide and methane.

EnDura comprises different elastomer types said to offer superior chemical resistance compared to conventional explosive decompression grades and greater high and low temperature capabilities. The range has been tested to the major international explosive decompression standards such as NOROSK M-710, and includes HNBR, TFE/P, and FKM elastomers.
