Tecnoflon® FKM and PFR FFKM

Tecnoflon® FKM and Tecnoflon® PFR FFKM are fluorocarbon synthetic rubbers with high fluorine content that provide best-in-class thermal and chemical performance among all other elastomers.

The Tecnoflon® family of fluoroelastomers and perfluoroelastomers offers a wide portfolio of materials to withstand the rigors of downhole, subsea and surface environments in the Oil & Gas industry. Tecnoflon® materials feature rapid gas decompression resistance, resistance to H2S and low temperature performance.

Typical applications in the Oil & Gas industry include stators for pumps and motors, packer elements and all types of sealing applications.

Tecnoflon® FKM/FFKM have a low compression set that is maintained at high temperature (>150°C) over time, resulting in better seals with higher and constant sealing force than materials like HNBR. This allows to increase the lifetime of the parts, reduce maintenance and shutdown times, and therefore decrease overall costs.

Tecnoflon® FKM Peroxide Curable and Base Resistant A full range of grades is available to match every specific requirement.

Low Temperature Performance: MOVE Technology

Tecnoflon® low temperature FKMs are designed using Solvay’s proprietary MOVE fully fluorinated monomer. These elastomers were developed for demanding applications, exposing them to aggressive chemicals and temperatures as low as –40°C.

Tecnoflon® VPL 85540 is the major exponent for the low temperature resistance technology.

Tecnoflon® PFR FFKM: the Ultimate Performance

Tecnoflon® PFR perfluoroelastomers are resistant to nearly every chemical class with some grades offering heat resistance over 300°C.

  • Tecnoflon® PFR 95HT uses Solvay’s proprietary cross-linking agent and will outperform triazinic curable FFKM’s under water and steam at high temperatures.
  • Tecnoflon® PFR LT uses Solvay’s proprietary MOVE technology, combining the perfluoroelastomer outstanding chemical resistance with unrivalled extended low temperature flexibility, with its TR10 = –30°C.
  • Tecnoflon® PFR 06HC exhibits the highest chemical resistance among all perfluoroelastomers. Specifically developed for the Oil & Gas industry, to withstand amines at high temperature and rapid gas decompression.

Rapid gas decompression

Rapid gas decompression occurs when the external gas pressure decreases rapidly in operation and can result in splitting, internal cracking and blistering of the seal.

Thanks to Solvay’s proprietary branching and pseudo-living technology, Tecnoflon® peroxide curable family of fluoroelastomers and perfluoroelastomers demonstrates excellent properties to withstand rapid gas decompression.

Most of Tecnoflon® FKM and Tecnoflon® PFR FFKM grades for the Oil & Gas industry were tested according to Norsok Standard M-710 Rev 2, and successfully passed the test.
