PP Injection Moulding Grades
Random and impact copolymer injection grades across a wide melt-flow range, combining random copolymer clarity with impact copolymer stiffness/impact balance.
Key properties
- MFR range 7.5–100.0 g/10min
- Random copolymer: high flow, clarity and organoleptic performance
- Impact copolymer: nucleated and antistatic options
