n response to standardization requirements of the oil and gas industry, Victrex Polymer Solutions contracted MERL to perform an investigation to evaluate the compliance of VICTREX® PEEK to the NORSOK M-710 Standard for sour (H2S) aging at 1,450 psi (10 MPa) and test temperatures of 175°C (347°F), 195°C (383°F) and 210°C (410°F) for up to five weeks. Results showed no measurable chemical deterioration for the VICTREX PEEK 450G in this time period of testing.
