PP impact copolymer
Moplen EP549U
Natural
Description
Moplen EP549U is a nucleated polypropylene heterophasic copolymer with antistatic additivation and an MFR of 70 g/10 min, a tensile modulus of 1260 MPa, and a Charpy impact strength of 9 kJ/m² at 23°C (6 kJ/m² at 0°C) -- a new-generation material engineered specifically for deep-freeze packaging and sub-zero food storage. With a ductile-to-brittle transition at -45°C, Moplen EP549U outperforms conventional copolymers in ice-cream containers, frozen-food lids, and cold-chain packaging where low-temperature drop-test survival is critical. Its 70 g/10 min flow rate delivers comparable mechanical performance to standard 45 MFR grades, enabling wall-thickness reduction and faster cycles.
Processing Techniques
Injection moulding on high-speed machines is the primary process for Moplen EP549U, and the high flowability supports wall-thickness reduction and lightweighting while controlled rheology ensures dimensional stability. Moplen EP549U performs best at melt temperatures of 210–240°C; its nucleation and antistatic package provide fast demoulding and static-free container handling on automated packing lines. Converters moving from conventional 45 MFR copolymers to Moplen EP549U can expect productivity gains without sacrificing the cold-impact performance that deep-freeze applications demand.
