Chemigum^® NBR elastomers, copolymers of acrylonitrile and butadiene, are known for their good mechanical properties and resistance to fuels, fats and oils. In PVC or CPE blends, they minimize the loss of liquid plasticizers due to extraction, volatility or migration, thus maintaining flexibility under harsh conditions.

Different grades have been developed in powder form to meet specific processing or end-use requirements.
