CERTENE™ PHM-12 PHM-12 is a certified prime grade Polypropylene designed for injection molding of general purpose applications. PHM-12 combines a good balance of medium-high flow processability with good tensile strength, high stiffness and good contact clarity. PHM-12 applications include thin-walled containers, housewares, medical ware, caps, closures, toys, and housings for small electrical appliances. PHM-12 recommended processing temperature is between 210° to 230°C with mold at 20°-50°C. PHM-12 complies with FDA regulation 21CFR 177.1520 and with most international regulations concerning the use of Polypropylene in contact with food.&&CERTENE™ PHM-12 PHM-12 is a certified prime grade Polypropylene designed for injection molding of general purpose applications.
