Performance & Applications
Defoaming & Cooling
- Antifoaming Agent: Ideal for coatings, hydraulic oils, synthetic rubber, and latex processing.
- Thermal Management: Used as antifreeze, coolant, and heat-transfer fluid with excellent heat/cold resistance.
Industrial Lubrication
- Metalworking: Additive for water-soluble cutting fluids, rolling oils, and hydraulic systems.
- Rubber & Synthetic Oils: Serves as internal/external lubricants and mold release agents.
Grade-Specific Applications
PPG-200/400/600: Water-soluble grades providing lubricity, solubilization, and antistatic properties. PPG-200 is an effective pigment dispersant, while PPG-400 serves as an emollient in cosmetics.
Intermediate Use: Used as a chemical intermediate in esterification, etherification, and polycondensation reactions.
PPG-2000 to 8000: High-molecular-weight grades with superior lubricity and antifoaming performance.
Polyurethane & Plastics: PPG-3000 to 8000 are core components for blended polyethers in polyurethane foam production and plasticizer manufacturing.
Packaging & Logistics
Standard Packing: 200 kg steel drums or 50 kg plastic drums.
Safety: Non-toxic and non-flammable; handled as general chemicals.
Storage Guidelines
Environment: Keep in a dry, well-ventilated warehouse.

Frequently Asked Questions about PPG
Q: What is the main difference between PPG and PEG?
A: While PEG is highly hydrophilic, PPG (Polypropylene Glycol) is less water-soluble at higher molecular weights and offers superior lubricity and defoaming properties for oil-based applications.
Q: Can PPG be used as a defoamer in food processing?
A: Our industrial-grade PPG is ideal for coatings, hydraulic oils, and synthetic rubber. For food-grade requirements, please contact our technical team for specific compliant grades.
Q: Do you support custom viscosity or molecular weight blends?
A: Yes, we offer custom synthesis and processing for special PPG grades beyond our standard range.
