As proof, it has used a TPO compound containing a mix of talc and Hyperform HPR-803i (total additive content around 10 % by weight) to mould prototype B-pillar covers that it normally supplies in a conventional 20 % talc-filled TPO. The prototype parts weighed 524 g, 7 % less than the commercial parts. The compound has a density of 0.98 g/cm3, which compares with 1.04 g/cm3 for a 20 % talc-filled TPO with similar mechanical properties. The compound is produced by Inno-Comp in Hungary.Nathalie Samson-Maguet, Mecaplast's Research & Innovation Manager, says its final product costs are exactly the same: Hyperform HPR-803i costs more than talc, but this is cancelled out by the reduced total material requirement. She further mentioned plans to use compounds containing Hyperform HPR-803i also for C-pillars and sill panels. The company is aiming to go into production with TPO parts reinforced with Hyperform HPR-803i within the next two years. According to Samson-Maguet, the company is also developing a new process, still confidential, that will yield Hyperform reinforced TPO interior and exterior parts between 35 and 40 % lighter than current versions. She says that for a typical C-segment car, use of compounds containing the Milliken additive in these parts alone could yield a total weight saving of at least 225 g, leading to a potential reduction in CO2 emissions of 0.022 g/km. In addition to reducing part weight, Hyperform HPR-803i can help improving the scratch resistance.
