Polimeri Europa Europrene® N 4560 Acrylonitrile-Butadiene Rubber

Europrene® N 4560 is a cold polymerized acrylonitrile-butadiene copolymer. A non staining antioxidant is added during the production process.Key Features: Europrene® N 4560 is characterized by the highest oil and aliphatic hydrocarbon swelling resistance among the Europrene N grades. Mechanical properties decay of articles based on this elastomer is very limited also after long contact time with fuels whereas permeability of vulcanized articles is very low. The vulcanization can be performed by sulphur based systems or by peroxides. The low temperature properties can be further 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 to the compounding process.Main Applications: Gaskets for oil bath, transformers, fuel hoses, oil sealing rings. gaskets for hydrocarbon ducts, flat gasket for carburetors, etc..Information provided by Polimeri Europa.
