EP-F 31 HR

EP-F 31 HR

EP-F 31 HR is an easy flow heterophasic polypropylene copolymer with an improved mechanical properties balance. The product features an high stiffness and an outstanding impact strength.
EP-F 31 HR is specifically designed for injection moulding applications.
EP-F 31 HR combines, high stiffness with an outstanding impact strength, even at low temperature.
In comparison to conventional copolymers with the same MFR and same rigidity EP-F 31 HR, exhibits a 20 % higher toughness.
EP-F 31 HR is suitable for a wide range of applications in the packaging, automotive and consumer goods industries. Typical applications include luggage, paint pails, buckets, containers, crates, batteries and large toys.
