′′Jampilen EPX-548T′′ 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 ′′Jampilen 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, ′′Jampilen EPX-548T′′ exhibits 15% higher rigidity. ′′Jampilen EPX-548T′′ is suitable for food contact.
