GAZGUARD 026

General description: Peroxide cured and carbon black reinforced Fluorcarbon Terpolymer based compound and

offers excellent resistance to Rapid Gas Decompression (RGD). Gazguard 026 has been designed with

outstanding mechanical properties for this polymer type.

Properties: In addition to excellent resistance to a wide range aliphatic and aromatic hydrocarbons and solvents,

Gazguard 026 offers good compression resistance and high elongation coupled with good extrusion resistance

and optimised performance in high pressure gas applications.

Temperature capability: -13ºC (9°F) to 210ºC (410°F) in air (higher temperatures possible in non oxidising

media)

Fluid immersion testing: Water 72 hours @98ºC (208ºF)

Rapid Gas Decompression (RGD) validation: The compound has been subjected to full 10 cycle RGD testing

at MERL UK independent test facility in accordance with Norsok M-710 rev 2. Test conditions were 90% Methane/

10% Carbon dioxide gas at 100º C and 150 Bar test pressure. The highest possible rating of 0000 was achieved

with no visible external or internal damage. A certificate is available on request.

Fluid immersion testing: 96% Methanol + 4% Water 72 hours @40ºC (104ºF)

Fluid immersion testing: Oil No. 1 (IRM 901) 72 hours @150ºC (302ºF)
