PP Fibre Grades
Homopolymer fibre grades for BCF, CF, staple and spunbond nonwovens, offering low density, spinnability, thermal bondability and breathability.
Key properties
- MFR range 3.0–38.0 g/10min
- Anti-gas-fading stabilisation on several grades
- Narrow MWD for fine filaments on high-output lines
