BARCELONA, Spain - Nubiola has recently expanded its manufacturing capacity of micronized red iron oxides (Nubifer Red 5000 series) by 20 percent in its Girardota (Colombia) production plant. The investment was approved last year; the expanded line has been working at full capacity since mid-2010.

The Nubifer 5000 series are micronized iron oxides that provide higher performance than conventional iron oxides, due to their higher dispersibility, narrower particle size distribution and lower sieve residue.
