PP 440L – Injection Moulding Grade
PP 440L is a medium-flow heterophasic copolymer combining high stiffness with outstanding low-temperature impact strength.
PP 440L is a medium-flow heterophasic copolymer with an improved balance of mechanical properties: high stiffness and outstanding low-temperature impact strength for injection moulding. It delivers about 35% higher toughness than conventional copolymers of the same MFR and rigidity.
