Selecting the Right PPG Grade
Low MW (PPG 425)
Flexible foam, lubricants, and hydraulic fluid applications requiring lower viscosity.
Mid MW (PPG 1000, 2000)
Polyurethane elastomers, CASE applications, and sealants requiring balanced flexibility and strength.
High MW (PPG 4000)
Specialty polyurethane and high-viscosity lubricant applications.
Industrial Applications
Polyurethane Production
Primary polyol in flexible and rigid polyurethane foam, elastomers, coatings, adhesives, sealants, and elastomers (CASE).
Hydraulic Fluids
Fire-resistant water-glycol hydraulic fluids for steel mills, die casting, and mining. PPG improves viscosity and lubricity.
Lubricants & Metalworking
Base fluid in synthetic lubricants, gear oils, and metalworking fluids. Excellent thermal stability and lubricity.
Functional Fluids
Heat transfer fluids, brake fluids, and compressor lubricants where low toxicity and biodegradability are required.
Surfactants & Demulsifiers
Building block for nonionic surfactants, demulsifiers, and defoamers used in oilfield and industrial applications.
Personal Care
Low-MW PPG grades used as emollients, solvents, and viscosity modifiers in cosmetics and personal care products.
Safety & Regulatory
SDS and certificate of analysis available for each grade upon request.

Polypropylene glycol (PPG) is a hydrophobic polyether diol used in polyurethane foams, lubricants, and surfactants.
| Attribute | Polypropylene Glycol | Polyethylene Glycol | Propylene Glycol |
|---|---|---|---|
| Hydrophobicity | High — water-insoluble at high MW | Hydrophilic — water-soluble | Fully water-miscible |
| Primary Use | Polyurethane, lubricants, surfactants | Pharma, cosmetics, resins | Food, pharma, HVAC |
| Grades Available | PPG 425, 1000, 2000, 4000 | PEG 200–8000 | USP, FCC, Industrial |
| Viscosity | Increases with MW (80–1000 cP) | Varies by MW | ~56 cP |
| Foam Tendency | Low — used as defoamer | Low | Very low |
