Shared Properties of DOW Polypropylene Glycols and Polyglycol Copolymers

Although each product has unique properties based on molecular weight and the monomer used, they al share some common properties.

Property Overview
Excellent solvency Polypropylene glycols and polyglycol copolymers dissolve or are compatible with many performance additives and are miscible in various organic liquids.
Lubricity DOW polypropylene glycols and polyglycol copolymers exhibit excellent film forming properties and low coefficient of friction.
High viscosity indices DOW polypropylene glycols and polyglycol copolymers have great viscosity versus temperature profiles making them an excellent choice as base stocks for synthetic lubricants.
Range of viscosity DOW polypropylene glycols and polyglycol copolymers cover a broad range of viscosity from very low to very high viscosity.
Low color and odor DOW polypropylene glycols and polyglycol copolymers are typically water white, with little or no odor.
Low ash, non-varnishing In high temperature applications and when burned, DOW polypropylene glycols and polyglycol copolymerstypically do not leave black carbon or sticky residues.
Chemical stability DOW polypropylene glycols and polyglycol copolymers do not hydrolyze or become rancid in storage. Recommended shelf life is two years.
Low flammability Flash points for DOW polypropylene glycols and polyglycol copolymers are greater than 150°C, making them safe to handle and store.
Toxicological and ecotoxicological profile Polypropylene glycols and polyglycol copolymers exhibit a low order of acute toxicity by ingestion or skin exposure. Aquatic toxicity is typically low and many of the products are biodegradable. Consult individual safety data sheets for more specific information.
