Dispergum Zinc Soaps

Dispergum zinc soaps act as lubricants and reduce the compound viscosity.

Features

Dispergum PT

Dispergum PT is a concentrated combination of zinc soaps with saturated?and unsaturated fatty acids. Dispergum PT improves the filler dispersion?and provides excellent flow properties and energy savings. Vulcanizates containing Dispergum PT show lower heat build-up values.

Dispergum E

Dispergum E

Dispergum E is a high-activity zinc soap with a particularly low dropping point. Dispergum E is suitable for compounding with low shear?force and for open mill mixing.

Dispergum R

Dispergum R is a zinc soap based on saturated and unsaturated
fatty acids. It also contains special paraffinic lubricants to improve
flow and demoulding properties.

Dispergum GT

Dispergum GT is a combination of zinc soaps and fatty acid esters. Dispergum GT improves the processing properties of light-coloured compounds containing light active fillers, and provides optimized dynamic values, e.g. hysteresis.

Dispergum ZK

Dispergum ZK is a zinc soap developed specifically for light as well as highly filled compounds. The special combination of zinc and potassium soaps enables excellent mixing and allows for high quantities of light fillers, such as china clay, chalk or silica, to be dispersed more easily.
