Minerals in Compounding 2011

AMI's Minerals are a major proportion of the additives used in compounding polymers with a key role in cost reduction as fillers. Many have other functions to add value, for example as flame retardants, conductive components and pigments. The mineral particle size, shape, surface area, matrix compatibility, and dispersion are all important factors affecting performance. It is also critical to understand mineral chemistry to choose the best products for each polymer. Surface treatments and modifiers can be utilized to improve mineral-polymer interaction and dispersion.
