Polypropylene typically has an MFI range of 0.1–100 g/10 min (measured at 230°C under 2.16 kg load). The MFI value indicates the material's flowability during processing:

Applications：

Low MFI (0.1–10 g/10min): Higher molecular weight, better mechanical strength (e.g., automotive parts, industrial containers).

Medium MFI (10–30 g/10min): Balanced flow and strength (e.g., household goods, packaging).

High MFI (30–100+ g/10min): Excellent flow for thin-walled or complex parts (e.g., fibers, disposable syringes).
