Under high pressure, gases tend to permeate the surface of an elastomer, seeping into the material’s core. This happens until the internal pressure of a material creates an equilibrium with the external pressure of the fluid media. If the external pressure experiences a sudden and significant drop, the gases that had permeated the elastomer escapes to maintain equilibrium. The gases migrate rapidly and beyond the elastomer’s capacity to handle that change. This causes fissures and ruptures, as shown in the pictures above, and is referred to rapid gas decompression (RGD) or explosive decompression (ED).

It is well-known that fluorocarbon (FKM), despite being a widely used material, typically has poor low-temperature capabilities. To provide our customers with a low-temperature FKM sealing solution that resists rapid gas decompression, we have formulated the V9M2 compound using Viton™ GLT polymer.

This specialty compound combines the high-temperature resilience of FKM with enhanced performance at lower temperatures, delivering a more versatile sealing solution. Its extremely low compression set is ideal for temperature and pressure cycling environments. It also has a strong resilience to a broad range of chemicals, including hot water and steam. V9M2 has undergone third-party testing for low-temperature valve sealing performance. It achieved an outstanding result at a temperature of -40°C per MESC 77/312 standards for Fugitive Emission Production Testing.

V9M2 Advantages:

  • Enhanced low-temperature capabilities
  • Proven resistance to rapid gas decompression (RGD)
  • Low gas permeability
  • Outstanding mechanical properties
  • Exceptional resistance to petroleum, oil, and gas
  • Resistant to a broad range of chemicals, including hot water and steam
  • Good resistance in corrosive environments • Superior performance in pressure and temperature cycling applications

V9M2 also has undergone thirdparty testing set by some of the industry’s most respected regulating bodies, including:

  • NORSOK M-710 (Rev.2) RGD
  • API 6A Sour Gas Service
  • NACE TM0297 RGD
  • TOTAL GS EP PVV 142 RGD

V9M2 is used in critical applications across numerous markets, including, drilling, completions, pumps, workovers, compressors, and valves. It is is ideal for O-rings, loaded U-cups, hammer union seals, and custom moulded products.
