Chemraz 678

Chemical Processing, Energy, Industrial Operations, Oil & Gas

Chemraz® 678 compound (90 durometer) expands the portfolio of low-temperature perfluoroelastomers and maintains excellent sealing integrity at high pressures and in temperatures as low as -40°F (-40°C). In addition, Chemraz® 678 has excellent RGD (Rapid Gas Decompression) properties as verified by an independent third-party lab*. Chemraz® 678 delivers the same exceptional chemical resistance as our other market-leading compounds along with a wide temperature range of -40°F to 445°F (-40°C to 230°C). This material also provides excellent compression set and thermal shock resistance, allowing our seals to be used in a wide variety of industry applications. The material also allows for greater flexibility in tooling due to a comparable shrink rate with our other high-performance sealing solutions.

Features & Benefits

Excellent RGD resistance reduces the risk of costly seal failure, loss of production time, and environmental damage
Exceptional performance in extreme low temperatures to enable applications in harsh environments
Superior resistance to hostile reservoir chemistries, drilling fluid additives, and production chemicals for improved sealing performance
Excellent compression set and thermal shock resistance for expanded application capabilities

Applications
