Polifil® GFRMPPCC

Polifil GFRMPPCC

Chemically Coupled High-Impact Glass-Reinforced Polypropylene

Polifil® GFRMPPCC series compounds are high impact polypropylenes reinforced with chemically coupled glass fibers. This combination provides higher impact strength while retaining high stiffness. These compounds are used in appliances, electrical components, automotive and utility products. Standard processing techniques are applicable.
