Milliken Chemical’s Hyperform HPR-803 high-performance reinforcing agent for polyolefins was developed to meet the needs of the automotive industry. By replacing high loadings of heavy mineral fillers, such as talc, with lower loadings for comparable performance, Hyperform HPR-803 reduces weight by up to 15% vs. traditional mineral-filled systems while delivering a balance of stiffness and impact strength. According to the company, the agent offers comparable surface finish to talc-filled compounds that cannot be achieved with chopped glass fiber reinforcement. Hyperform HPR-803 provides high heat deflection temperatures exceeding high levels of talc. These features allow customers to improve the appearance, performance, and productivity of their products. By using Hyperform HPR-803 reinforcement as a replacement for chopped glass fiber, customers can expand applications for polypropylene and other polyolefins beyond current “hidden” structural automotive parts to encompass highly visible components such as bumpers and door panels.
