Typical Properties (Representative Values):

Please note that specific values may vary slightly depending on the exact production batch and testing conditions. Always refer to the official Technical Data Sheet (TDS) from LyondellBasell for the most accurate and up-to-date information for this specific grade.

• Melt Flow Rate (MFR) (230°C / 2.16 kg): 25 – 40 g/10 min (ISO 1133)
• Density: ~0.90 – 0.91 g/cm³ (ISO 1183)
• Tensile Strength @ Yield: 25 – 30 MPa (ISO 527-1, 2)
• Flexural Modulus: 1200 – 1500 MPa (ISO 178)
• Notched Izod Impact Strength (23°C): 25 – 40 kJ/m² (ISO 180/1A)
• Notched Izod Impact Strength (0°C): 10 – 20 kJ/m² (ISO 180/1A)

• Vicat Softening Temperature (A/50): ~135 – 140 °C (ISO 306)

Processing Guidelines (Injection Molding – General):

• Drying: Generally not required for polypropylene, but proper storage to prevent moisture absorption is recommended.
• Melt Temperature: 190 – 230 °C (optimize based on machine type, mold design, and part thickness).
• Mold Temperature: 20 – 50 °C (higher mold temperatures can improve surface finish and reduce internal stress).
• Injection Speed: Medium to high, to ensure good mold filling and reduce cycle times.
• Holding Pressure: Optimized to prevent sink marks and ensure dimensional accuracy.
