| PHM-5A is a certified prime grade Polypropylene specially designed for extrusion and injection molding applications. PHM-5A contains antistatic and combines good processability and high thermal stability, with medium flow, high tensile strength, good stiffness and good contact clarity. PHM-5A applications include drinking straws, small profiles, housewares, toys, and technical parts subject to normal stresses. PHM-5A recommended processing temperature is between 210° to 230°C. PHM-5A complies with FDA regulation 21CFR 177.1520 and with most international regulations concerning the use of Polypropylene in contact with food. Specific certificates are available upon request.&& |
