Reactive Extrusion of Injection-Grade Polypropylene Toward Controlled-Rheology Materials for Spunbond Manufacturing

Gianluca Palangio, Maria Pia Desole, M. Barletta, Annamaria Gisario

Short summary

Adding 0.5 wt% Nexamite R202 to injection-grade polypropylene increased melt flow rate by 167% (from 12.5 to 33.3 g/10 min) and reduced tensile stress and impact energy, enabling controlled-rheology materials for spunbond manufacturing.
