Material Notes:
Polifil® RP-PP reprocessed polypropylene has the highest stiffness of the commodity olefin resins, while retaining sufficient impact properties for many applications. Due to its low cost and low density, polypropylene use has been expanding rapidly, and common uses now include injection molded articles, fibers, packaging films, and extruded sheet and profiles. Polypropylene is widely used in injection molding for housewares, appliances, and automotive parts. High flow grades are spun into fibers, and molded into thin wall containers, cups, and lids. Moderate flow resins are common in general injection molding and cast films. High molecular weight, low flow grades are extruded into sheet and profiles, and blow molded into automotive parts and recreational goods.Information provided by The Plastics Group.
