A new type of synthetic reinforcing fibers has been made available enabling the production of automotive parts made of polypropylene (PP), with weights up to 15 % below those of conventional parts, without any compromise in performance. The product named Hyperform HPR-803i is supplied by Milliken in Gent, Belgium. Producing polypropylene compounds, it can be used at a filling level lower than is possible with mineral fillers, as a result leading to lower density in the compound. Whether used as sole reinforcing fiber or together with talcum, it helps automotive manufacturers achieve their goals, i.e. reducing weights and producing cars with reduced consumption of fuels and low emissions.
Hyperform HPR-803i compounds are suitable for injection molding processes. Designed originally for talcum-filled compounds, they simplify inspection requests and cut the cost of implementation. PP compounds reinforced with HPR-803i maintain their mechanical properties even after several recycling and compounding cycles. Processors can reduce the use of pigments, while at the same time meeting color requirements. The fibers improve the part’s impression as well as scratch appearance.
