Overview
In plastic applications, polypropylene glycols (PPGs) are used as radiation stabilizers, and as additives to impart anti-static and scratch resistance properties.

Products
The following polypropylene glycols and polyglycol copolymers can be used in plastics applications. Although each product has unique properties based on the molecular weights and the oxides used, they all share some common properties.

Polypropylene Glycols Polyglycol Copolymers
P425 15-200
P2000
P4000

Specific Applications
Radiation stabilizers
PPGs can be used for stabilizing polycarbonate against gamma radiation by acting as the "radical scavenger". If the radicals were to form in the polycarbonate, the resin turns a yellow to brown color.

Anti-static and scratch resistance
Polyglycol P4000 has shown good scratch resistance in ABS and High Impact Polystyrene.
