 The Nubifer 5000 series are micronized Iron Oxides manufactured with a special process that minimizes the presence of agglomerates. The Nubifer 5000 series provide higher performance vs conventional Iron Oxides mostly because of its higher dispersibility, narrower particle size distribution and lower sieve residue. Therefore customers will be able to load more pigment in their Masterbatches and to achieve a better performance of their products in end use e.g. especially in critical applications like thin films.  In order to provide an enhanced product quality consistency, the 5000 series’ color specs are significantly narrower than conventional Iron Oxides’, thus ensuring minimum lot to lot color variations. As regards coloristics of the 5000 series:
