Inorganic nanomaterial additives in polymer composites are in the early stages of demonstrating that they are capable of extending the limits of performance with associated cost effectiveness in many polymer composites at extremely low loading levels. For several years nano-clay has led the way with technological innovation and a certain amount of success. To date no other nano-scale platelet type products were available for evaluation. NANOTALC~R is a new, breakthrough, non-hazardous, nanomaterial additive which can provide superior enhancement in certain polymers. One area for potential application is high performance, appearance driven TPO applications, which require an excellent balance of mechanical, chemical and visual properties. NANOTALC ~R is Magnesium Silicate (talc). It is a high aspect ratio, ～100-nanometer platelet, with a surface area of 200-400 square meters per gram. It has an active, selective surface, which allows for the use of a variety of resin specific surface modification techniques and coupling agents. Nanova, LLC will discuss some initial results, which indicate NANOTALC ~R may provide: 1. High Distinctness of Image 2.Improved scratch resistance 3. Lower loading (2-4%) 4. Excellent CLTE 5. Excellent melt flow characteristics 6. Excellent impact properties 7. Excellent Flexural Modulus 8. Ease of processability Our presentation will focus on the importance of morphology, surface area, surface chemistry kinetics and surface modification. We will show performance expectations and initial results from compounded TPO, molded / extruded samples and thin film composites.
