Overview
In paper processing applications, polypropylene glycols and polyglycol copolymers are typically used as processing aids (defoaming and deinking agents). They are also used as additives, to achieve specific properties within the final paper product.
Products
The following products can be used in paper processing applications. Although each product has unique properties based on molecular weight and the monomer used, they all share some common properties.

Specific Applications
Defoaming
Polypropylene glycols and EO/PO block copolymers are very effective foam control agents in the paper making process.
Deinking Surfactants
Fattyalcohol and other hydrophobic initiated alkoxylates are very effective surfactants for the removal of ink from waste paper in the flotation process.
