Chemraz® 564/566 LT

Low Temperature Material Delivers Exceptional Performance in Extreme Environments


As the temperatures and pressures in exploration and completion environments become more extreme, the stress placed on the tools that enable these applications dramatically increase. From fluid-filled wireline tools and motors stored and utilized in arctic temperatures to drilling equipment operated in the near freezing conditions of deepwater drilling, the oilfield industry requires
a sealing solution that can withstand these increasingly harsh situations. Greene, Tweed’s Chemraz® 564 LT (80 durometer) and Chemraz 566 LT (90 durometer) deliver exceptional performance in severe low temperatures – maintaining excellent sealing integrity at high pressures and in temperatures as low as -40°F (-40°C).

Chemraz 564 LT and Chemraz 566 LT deliver 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). These new materials also provide excellent compression set and thermal shock resistance, allowing these seals to be utilized in a wide variety of industry applications. In addition, the materials allow for greater flexibility in tooling due to a comparable shrink rate with our other high-performance sealing solutions.


  •  Exceptional performance in extreme low temperatures to enable increasingly harsh environmental applications
  •  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
