11. PP Properties and Technical Report
| Property | Typical Range |
|---|---|
| Density | 0.895 to 0.93 g/cm³ |
| Melt Flow Index (MFI) | 0.1 to 30 g/10 min |
| Tensile Strength | 30 to 40 MPa |
| Flexural Modulus | 1300 to 1800 MPa |
| Impact Strength | Moderate to High |
| Melting Temperature | 130°C - 171°C |
| Chemical Resistance | Excellent against acids and bases |
MFI (Melt Flow Index) helps determine the flowability of PP during molding operations.
