PERFORMANCE OF NANOTALC ? SUPERFINE POWDERS

摘要

Inorganic nanomaterial additives in polymer composites are in the early stages ofrndemonstrating that they are capable of extending the limits of performance withrnassociated cost effectiveness in many polymer composites at extremely low loadingrnlevels. For several years nano-clay has led the way with technological innovation and arncertain amount of success. To date no other nano-scale platelet type products werernavailable for evaluation.rnNANOTALC? is a new, breakthrough, non-hazardous, nanomaterial additive which canrnprovide superior enhancement in certain polymers. One area for potential application isrnhigh performance, appearance driven TPO applications, which require an excellentrnbalance of mechanical, chemical and visual properties.rnNANOTALC ? is Magnesium Silicate (talc). It is a high aspect ratio, ～100-nanometerrnplatelet, with a surface area of 200-400 square meters per gram. It has an active, selectivernsurface, which allows for the use of a variety of resin specific surface modificationrntechniques and coupling agents.rnNanova, LLC will discuss some initial results, which indicate NANOTALC ? mayrnprovide:rn- High Distinctness of Imagern- Improved scratch resistancern- Lower loading (2-4%)rn- Excellent CLTErn- Excellent melt flow characteristicsrn- Excellent impact propertiesrn- Excellent Flexural Modulusrn- Ease of processabilityrnOur presentation will focus on the importance of morphology, surface area, surfacernchemistry kinetics and surface modification. We will show performance expectationsrnand initial results from compounded TPO, molded / extruded samples and thin filmrncomposites.
