Dispergum E
Dispergum E is a pure zinc soap of high activity which has a particular low dropping point and is therefore suitable for compounding with low shear forces and for open mill mixing. *BfR, FDA

Dispergum GT
Dispergum GT is a special combination of zinc soaps and fatty acid esters, designed for applications including high amounts of active filler (e.g. silica). Dispergum GT improves the dispersion and facilitates the processing of those compounds. The use of Dispergum GT leads to vulcanizates with optimized dynamical properties, e.g. hysteresis. *BfR, FDA

Dispergum PT
Dispergum PT is a concentrated combination of zinc salts of saturated and unsaturated fatty acids. Dispergum PT improves the dispersion of filler and other ingredients, and leads to excellent flow properties and energy savings. Vulcanizates with Dispergum PT show lower Heat Build Up values. *BfR, FDA

Dispergum R
Dispergum R is a zinc soap of high activity, based on saturated and unsaturated fatty acids and special paraffinic lubricants. Dispergum R improves the flow and demoulding properties. Depending upon the fatty acids used, the colour of Dispergum R may vary from beige to brown. *FDA
