Chemraz® 554 LT (80 durometer) and Chemraz 546 LT (90 durometer) are designed for use in valves, compressors and pumps stored and operated in arctic environments. Subzero conditions place enormous stress on process equipment, and temperatures are typically beyond the capabilities of perfluoroelastomers (FFKM). Chemraz 554/546 LT overcome this limitation, maintaining seal integrity at high pressures and in temperatures as low as -40°F (-40°C).
Chemraz 554/546 LT deliver the same exceptional chemical resistance, compression set and thermal shock resistance as our other market-leading compounds. They also feature a comparable shrink rate, allowing for greater flexibility in tooling. A wide temperature range of -40°F to 445°F (-40°C to 230°C) makes them suitable for a variety of industry applications.
