Compatibilizer for polymer blends

COMPOSITION:Mixture of dark aromatic hydrocarbon resins.

RECOMMENDATIONS FOR APPLICATION:

ULTRA-BLEND™ 4000 improves the homogeneity of polymerblends of different polarities or different viscosities. It is quickly absorbed by the polymer matrix by wetting out the surfaces which leads to a fast incorporation of other compound ingredients.

The reduction of viscosity assists down line processing, in particular milling and calendering.

ULTRA-BLEND™ 4000 is best added at the beginning of the mixing cycle to achieve the optimum wetting effect.

ULTRA-BLEND™ 4000 increases green tack of compounds by showing some synergism with tackifiying resins.

Due to its dark colour, ULTRA-BLEND™ 4000 is not recommended for light coloured compounds.
