EUROPRENE® N 3945

EUROPRENE® N 3945 by Versalis (Eni Group) is a cold polymerized acrylonitrile-butadiene copolymer. A non-staining antioxidant is added during the production process. The vulcanization can be performed using a sulfur-based system or with peroxides. The low-temperature properties can be improved by adding polar plasticizers as synthetic esters of adipic, sebacic or phthalic acids. To improve heat, light and ozone resistance, suitable protective agents as amine or phenolic antioxidants have to be added in the compounding process. The high ACN content confers to compounds based on EUROPRENE® N 3945 has good hardness properties, good oil and aliphatic hydrocarbon swelling resistance. It is used in a wide range of technical articles requiring good processability and a very high oil and fuel resistance. It has a shelf life of 24 months.
