Europrene® N 3945 GRN

Europrene® N 3945 GRN is an advanced technology cold polymerized acrylonitrile-butadiene copolymer made at the PortoTorres production facility in Italy. A non staining antioxidant is added during the production process.

Europrene® N 3945 GRN is characterised by excellent processability and tear resistance at high temperature, good dimensional stability both in calendering and in extrusion. GRN grades show higher cure rate, higher low temperature flexibility, higher crosslinking density and better mechanical properties, better oil and fuel resistance in comparison to STD grades. The improved processability guarantees low mould fouling products and then long production runs, lower mould wear and less production controls. The medium ACN content gives a very good compromise to get both low temperature flexibility and oil resistance. The vulcanization can be performed by sulphur based systems or by 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. Suitable for injection applications (low mould fouling).
