The ASTM D4101-2017 standard covers polypropylene (PP) materials suitable for injection molding and extrusion, including different types such as unreinforced, calcium carbonate filled, Glass reinforced, talc filled, and polypropylene (PP) copolymers. The specification specifies physical and Mechanical Property requirements for materials such as Nominal Flow rate, specimen size, yield tensile stress, flexural modulus, cantilever impact resistance, deflection temperature, and multiaxial Impact ductility-brittle transition temperature. The standard allows the use of recycled, reconstituted, and re-ground polypropylene (PP) materials, provided that specified requirements are met and food contact regulations or similar standards are met.
