PP Compounding Grades
Impact copolymer grades positioned for compounding, with high flexural modulus and impact resistance at room temperature across a medium-to-very-high flow range.
Key properties
- MFR 7.5–100.0 g/10min
- Tensile modulus 1150–1550 MPa
- Notched Izod impact (+23 °C) up to 50 kJ/m²
