ULTRA-BLEND™ 4000 improves the homogeneity of polymer blends of different polarities or different viscosities.
ULTRA-BLEND™ 4000 is quickly absorbed by the polymer matrix by wetting out the surfaces which leads to a fast incorporation of other compound ingredients.
It is best added at the beginning of the mixing cycle to achieve the optimum wetting effect.
ULTRA-BLEND™ 4000 increases green tack of rubber compounds by showing some synergistic effect with tackifying resins.
* The morphology of the product can slightly change over several months of storage time. A softening point increase within the range of several degrees is typical.
