CERTENE™ PHF-4

About
CERTENE™ PHF-4 PHF-4 is a certified prime grade Polypropylene specially designed for extrusion of profile and cast film applications. PHF-4 combines excellent processability and high degree of thermal stabilization, with good melt strength, high tensile strength and good fibrillation tendency. PHF-4 applications include stretched tapes, drinking straws, monofilament yarns for rope, fibrillated tape for twine, and flat films. PHF-4 recommended processing temperature is between 210° to 230°C. PHF-4 complies with FDA regulation 21CFR 177.1520 and with most international regulations concerning the use of Polypropylene in contact with food.&&CERTENE™ PHF-4 PHF-4 is a certified prime grade Polypropylene specially designed for extrusion of profile and cast film applications.
