“MCP EP440G” is a nucleated heterophasic copolymer especially developed for extrusion applications. In comparison with standard polypropylene copolymers with the same fluidity, “MCP 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 “MCP EP440G” are thermoforming, corrugated board and extrusion low molding.
