Europrene® N 3945 is a cold polymerized acrylonitrile-butadiene copolymer made at the Porto Torres production facility in Italy. A non staining antioxidant is added during the production process.

The high ACN content confers to compounds based on Europrene® N 3945 good hardness properties and good oil and aliphatic hydrocarbon swelling resistance. The vulcanization can be performed using a sulphur based systems or with peroxides.The low temperature properties can be improved by adding polar plasticizers as synthetic esters of adipic, sebacic or phtalic acids. To improve heat, light and ozone resistance, suitable protective agents as amine or phenolic antioxidants have to be added in the compounding process.

Wide range of technical articles requiring good processability and a very high oil and fuel resistance.
