New Non-fluoro Process Aid Additives Formulations For PC And PP

摘要

New non-fluoro process aid additives performance to improve flow properties of polycarbonate (PC) and polypropylene (PP) are discussed. The new formulations provide increased output and reduce torque during processing of the polymers by improving the flow properties while maintaining stability as indicated by measurement of melt flow index. It was found that in the case of their use in PC, the effect is achieved without causing hydrolysis of the polymer. The new additives are effective at very low addition levels (0.05%) and one of the formulations can be used for clear PC or FDA applications.
