Research output: Chapter in Book/Report/Conference proceedingConference contribution


Detailed application data is presented for the newly developed additive formulations designed for their use in surface enhancement of TPO polymers with improved flow and scratch properties. Improvements in impact properties and talc dispersion have been achieved with newly developed additives. Excellent scratch resistance performance has been achieved in TPO when used at 1-3% loadings without negatively affecting key physical properties. Recent work conducted on flow and release property enhancers for polyolefins are discussed. It is shown that significant performance improvements in PP /TPO polymers can be obtained at low loadings of these process aids. In addition to mechanical properties, Theological data is presented. It is shown that tailor making the additive formulations can achieve optimal scratch performance required for automotive interior/exterior applications.
