Polymers High Standards In Low Temperature

Editor: Dominik Stephan

Precision Polymer Engineering (PPE) have launched the latest addition to their extreme low temperature Perlast ICE range: Following the success of Perlast ICE G75LT (a 75 durometer material launched earlier this year) PPE have developed Perlast ICE G90LT; a new 90 durometer, low temperature, perfluoroelastomer compound with exceptional explosive decompression (ED) resistance for high pressure environments.

Both Perlast ICE materials offer a very good chemical resistance superiority that is typical for perfluoroelastomer (FFKM) in combination with extremely low temperature capabilities down to -46° C (-51° F). these properties make them suitable for use in API 6A and 6D wellhead equipment and pipeline valves, the manufacturer states. During recent trials, Perlast ICE G90LT testing was carried out at a pressure of 1200 psi which demonstrated that the material could provide sealing down to -50° C (-58° F), says PPE. This exceptional temperature resistance could make Perlast ICE G90LT a sought after perfluoroelastomer sealing material for the oil and gas industry, especially for applications in remote locations or in demanding sub-zero environments, the manufacturer believes.
