Product Description: Proaid AC-740 is a mixture of dark aromatic hydrocarbon resins designed to act as a unique processing aid for homogenizing polymer blends. It is quickly absorbed by the polymer matrix by wetting out the surfaces which leads to fast incorporation of other compound ingredients. Proaid AC-740 is best added at the beginning of the mix cycle to achieve the optimum effects. Applications: The dosage for Proaid AC-740 is 4 to 15 phr. Proaid AC-740 may be used: - Primary Function: To greatly improve homogeneity of polymer blends of different polarities or different viscosities.
- To increase green tack of compounds by showing some synergism with tackifying resins.
- For reduction of viscosity which assists down line processing, in particular milling and calendering.
- Due to its dark color, AC-740 is not recommended for light colored compounds.
