FKM O Rings are widely used in every industry: Automotive, Mechanical Equipment, Construction, Home Appliance, Aviation, Office Facilities, etc.
Nitrile / NBR usage:
They should be kept from direct sunlight. However, this can be improved through compounding. NBR is the standard material for hydraulics and pneumatics. NBR resists oil-based hydraulic fluids, fats, animal and vegetable oils, flame retardant liquids (HFA, HFB, HFC), grease, water, and air. Special low-temperature compounds are available for mineral oil-based fluids. By hydrogenation, carboxylic acid addition, or PVC blending, the nitrile polymer can meet a more specified range of physical or chemical requirements.
The quality of Nitrile-compounds depends on the percentage of acrylonitrile in the base polymer. The following table indicates the change of properties as a function of acrylonitrile content.
