Dispergum E

 Dispergum E is a zinc soap.

BEHAVIOUR AND EFFECTS:
Dispergum E is a processing additive which acts as lubricant and shows a reducing effect on viscosity. It facilitates mixing and processing, energy can be saved by cooler mixing process and lower viscosities. As an additional effect the dispersion of fillers and other ingredients is improved in NR, SBR and NBR-compounds.

APPLICATIONS:
As a dispersing agent and as mild peptizer in masticatable polymers. Dispergum E is a pure zinc soap of high activity with a particular low dropping point and is therefore suitable for compounding with low shear forces and for open mill mixing. For extruded sections and intricate moulds, microcellular rubber, injection and transfer moulding as well as for soft coumpounds blended in internal mixers.
 

 STORAGE AND HANDLING:
 Store in a cool, dry place away from any direct source of heat and moisture.
Shelf Life is min. one year in the originally sealed package under the recommended storage conditions.
