PP impact copolymer
Moplen EP548U
Natural
Description
Moplen EP548U is a nucleated polypropylene heterophasic copolymer with antistatic additivation, delivering an MFR of 70 g/10 min, a tensile modulus of 1450 MPa, and a Charpy impact strength of 4 kJ/m² at 23°C -- a new-generation material that matches the mechanical performance of conventional 45 MFR grades at significantly higher flow. Moplen EP548U is specifically engineered for IML thin-wall packaging, margarine tubs, dairy containers, lids, and housewares, with wall-thickness reduction potential that supports lightweighting initiatives. The tailor-made demolding behaviour and food-contact compliance of Moplen EP548U make it a standout choice for converters upgrading to faster production cycles.
Processing Techniques
Injection moulding on high-speed machines is the primary process for Moplen EP548U, and the 70 g/10 min MFR facilitates wall-thickness reduction while maintaining excellent dimensional stability through controlled rheology. Moplen EP548U's nucleation and antistatic formulation enable easy demoulding and static-free part handling, reducing scrap and downstream cleaning. Process at 210–240°C melt temperatures and fine-tune hold pressure to exploit the lightweighting potential without sacrificing the 1450 MPa stiffness.
