Acrylonitrile butadiene rubber (NBR - Nitrile Rubber)
Temperature Range: – 30°C to 100°C
Can be made to resist up to -50°C upon request
Chemically resistant to: Oil & Fuels, Mineral and Vegetable Oils, Grease, Water, Alcohol, and Aliphatic Hydrocarbons
Features such as FDA Compliant NBR Available
Fluorocarbon Rubber (FKM/FPM) Commonly Known as VITON®
Resistant to Aromatic & Aliphatic hydrocarbons.
High Pressure resistant suitable for Vacuum Applications
Good weathering, aging, and ozoning resistance.
Temperature Range: – 20°C to 200°C
Can be made to resist extreme temperatures and gases depending on categories as below:
General Chemical Resistant : Petroleum Oils & Fuels, Mineral Oils and Grease, Acids
Added Chemical Resistance of Viton AED (LT) : H2S (Hydrogen Sulfide) also known as sour gas
Ethylene Propylene Diene Monomer (EPDM) Rubber
Good Ozoning and Weather Resistance
Hot water, steam and sunlight resistant
Temperature Range: – 50°C to 150°C
Chemical Resistance : Glycol, Inorganic (Diluted) acids and Alkaline Solvents
Special Feature : Can be peroxide cured (FDA Compliant) for increased temperature resistance
Chloroprene Rubber (CR - Commonly Known as Neoprene)
Perfect compatibility with Ammonia, Acetone and low pH Acids
Strong wear, UV, flame and ozoning resistance
Appropriate for air sealing, Petrol & Vegetable oil
Temperature Range: – 30°C to 120°C
Carboxylated Nitrile Rubber (XNBR)
Better suited for dynamic applications compared to NBR as higher wear resistance, elongation and tensile
Suitable for Hydraulic Oils and other liquids similar to NBR
Temperature Range: – 30°C to 100°C
Hydrogenated Nitrile Rubber (HNBR)
Good resistance to oils, diluted acids, hydraulic fluids
Optimum used in Oil & Gas fields as it can be modified to be resistant to sour gas (H2S)
Variations : HNBR AED, HNBR AED LT, HNBR AED LT [Peroxide Cured], HNBR Peroxide Cure
Temperature Range: – 30°C to 150°C
AED [H2S] Range: -35°C to 160°C

Added Heat resistance
General FVMQ Temperature Range: -60°C to 170°C
Epichlorohydrin (ECO Rubber)
This elastomer bridges the gap between NBR and FKM, it is widely used for fuel applications
It can also replace butyl rubber where gas permeability and hydrocarbon fuels are concerned
Good wear and ozone resistance
Temperature Range: -40°C to 135°C
