Armowax W-440 is a polymeric ester of a long-chain alcohol, which means the molecule contains hydrophobic as well as hydrophilic groups. For that reason, it is also described as a double comb polymer. The combination of hydrophobic and hydrophilic groups provides improved wetting of the filler surface by the polymer matrix, ensuring optimum dispersion.
Common Applications: Armowax W-440 is a unique processing aid and compatibilizer for highly filled polyolefins. It is also suitable for engineering polymers and elastomers. It offers remarkable improvement in processing behavior and properties of the filled polymer compounds.
