“MCP EP548T” is a high melt flow rate, nucleated heterophasic copolymer with a special antistatic additivation used for thin-wall injection molding, IML and houseware applications. The product features improved balance of mechanical properties. The use of “MCP EPX-548T” allows high productivity due to the easy mold filling and short cycle times.
In comparison with conventional copolymers with the same MFR and the same toughness, “MCP EP548T” exhibits 15% higher rigidity. “MCP EP548T” is suitable for food contact.
