PDF Elastomer Storage Guidelines

Freudenberg Oil and Gas Technologies’ elastomer research group is focused on developing new formulations targeted for solving the most stringent challenges encountered by materials used in the oil and gas industry, from extreme temperature and pressure conditions, to exposure to harsh drilling and completion fluids.

We have developed a full-range of proprietary elastomers, from commercial NBR, HNBR, NR, and EPDM base polymers, to high-performance FKM grades, including GAZGUARD® - our patented RGD-resistant compounds. Our lab located in Houston, Texas, enables us to develop –and test in-house– new elastomer material recipes for a wide range of industry and customer-specific applications.

Comments

Nitrile (NBR)

Acrylonitrile- butadiene polymer

-58° to +240° F
(-50 to 115°C)

General service. Properties vary depending on Acrylonitrile content. Low temperature versions have limited hydrocarbon performance

Natural Rubber (NR)

Polyisoprene from plant sources

-50° to +220° F
(-45 to 105°C)

Excellent low temp flexibility and tear/wear resistance. Poor resistance to hydrocarbons.

Hydrogenated Nitrile sulphur cured (HNBR, HSN)

Hydrogenated acrylonitrile- butadiene polymer

-13° to +260° F
(-25 to 130°C)

General service. Improved wear and abrasion resistance. Lower chemical and thermal performance to peroxide cured grades

Hydrogenated Nitrile peroxide cured (HNBR, HSN)

Hydrogenated acrylonitrile- butadiene polymer

-13° to +320° F
(-25 to 160°C)

General service. Improved wear and abrasion resistance. Low acrylonitrile grades available for use at -40°F (-40°C)

Ethylene Propylene
(EPR, EPDM)

Ethylene propylene (diene) polymers

-40° to +250° F
(-40 to 120°C)

Aqeuous service. Not suitable for prolonged contact with hydrocarbons. Can be used in steam/hot water at 360°F (180°C)

Carboxylated Nitrile (XNBR)

Carboxylated Acrylonitrile- butadiene polymer

-13° to +250° F
(-25 to 120°C)

Improved wear properties. Limited resistance to steam and hot water

GAZGUARD®

Proprietary, high performance RGD-resistant range of compounds using a range of polymer types

-40° to +410° F (-40° to 210°C) depending on grade

Ideal for high pressure gas applications. Tested in gas and sour fluids in accordance with Norsok M-710

Fluorocarbon
(FKM, FPM)

Fluoroelastomer polymers

-10° to +430° F
(-23 to 220°C)

Suitable for high temperature, aliphatic and aromatic hydrocarbons. Special low temperature grades available for use at -40°F (-40°C)

Perfluorocarbon (FFKM)

Perfluoroelastomer polymers

10° to 500°F
(-12 to 260°C)

Highest thermal and chemical resistance. Some grades suitable for use at over 600°F (315°C)

Aflas® (FEPM)

Tetrafluoroethylene and propylene

40° to +440° F
(5 to 225°C)

Suitable for high temperature and aggressive chemical environments including sour (H2S). Can be used in steam/hot water at 500°F (260°C)

Polyurethane (AU, EU)

Polyurethane

-10° to +200° F
(-23 to 95°C)
