Brighter high performance polypropylene parts with low weight, increased stiffness, temperature resistance

03-Nov-10

The new Hyperform® HPR family of reinforcing additives from Milliken provides processors with a new option for making high performance polypropylene parts with low weight. Hyperform® HPR-803 is intended primarily for the automotive sector. Milliken plans future innovations aimed at applications in automotive, appliances and elsewhere. “We envisage HPR-803 being used mainly in automotive applications, but are not limiting our project scope,” says Adam Watson, in charge of marketing for the Hyperform HPR range. “It enables the production of polypropylene compounds that have mechanical performance similar to or better than mineral filled compounds, but at lower weight.” HPR-803 fibers have a high aspect ratio of around 40:1. “We expect PP compounds containing HPR-803 to replace talc-filled types and possibly other non-PP-based materials too,” says Watson. “Tests have also demonstrated that HPR-803 works very well in combination with talc, giving processors and end users the opportunity to convert to the new technology in a step-by-step fashion.”
