Chemraz® 555

Greene Tweed developed Chemraz® 694, a perfluoroelastomer, for exceptional chemical resistance and best-in-class performance in high-temperature steam environments, including steam assisted gravity drainage (SAG-D) and other enhanced oil recovery (EOR) applications requiring steam injection. Chemraz 694® can be used in typical oilfield applications where sustained high-temperature resistance is a requirement.

With the increased use of steam injection as an EOR technique in maturing, as well as heavy oil fields, Greene Tweed has responded to the market demand for reliable and extended downhole service life capacity for sealing materials for that environment.

Retains physical properties in a hot steam environment, thus reducing mean time between failure (MTBF) of elastomeric components in critical steam environments
Superior resistance to hostile reservoir chemistries, drilling fluid additives, and production chemicals for improved elastomeric performance
Excellent compression set and thermal shock resistance for increased reliability of components used in critical steam and high-temperature environments
