A generic term comprising the various copolymers of butadiene and acrylonitrile. the copolymers vary essentially in butadiene-acrylonitrile ratios, Mooey values and staining properties. They are resistant to solvents, oils, and greases and to bent and abrasion. Some trade names are Chemigum, Krynac, Nipol, Hycar, and Paracril. The Germans first produced the nitrile rubbers and called them Buna N and Perbunan.
A rubbery copolymer of butadiene and acrylonitrile. It is usually compounded and vulcanized.
A synthetic rubber which is highly oil resistant.
a membrane whose predominant resinous ingredient is a synthetic rubber made by the polymerization of acrylonitrile with butadiene.
a copolymer of acrylonitrile and butadiene made in particular for oil resistance (also known as NBR or the older term Buna-N); available in many grades, also sometimes in combination with PVC polymer (polyvinyl chloride) for improved processing and ozone resistance
Copolymer of butadiene and acrylinitrile. Butadiene generally is derived from petroleum and acrylonitrile from ethylene oxide and hydrogen cyanide. Names for nitrite rubbers include: Butraprene, Chemigum, Hycar, Perbunan and Paracril.
Emulsion copolymers of Butadiene and Acrylonitrile in varying proportions. This chemical is used in the manufacture of expanded rubber primarily for its resistance to swelling in oils and solvents.
Nitrile rubber is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Some trade names are: Nipol, Krynac and Europrene.
