′′Jampilen EP440G′′ is a nucleated heterophasic copolymerدespecially developed for extrusion applications. In comparison with standard polypropylene copolymers with the same fluidity, EP440G exhibits higher stiffness, superior impact properties at room and sub-zero temperatures, very high dimensional stability and excellent creep and deforming resistance. The main applications of EP440G are thermoforming, corrugated board and extrusion blow molding.
