1. For Polyurethane Production: Polypropylene glycol (PPG, CAS 25322-69-4) is a key polyether polyol raw material for flexible and rigid polyurethane foams, coatings, adhesives, sealants and elastomers (CASE), providing tailored reactivity, softness and mechanical performance.
2. For Synthetic Lubricants: PPG serves as a synthetic lubricant base oil for gear oils, compressor oils and hydraulic fluids, offering excellent viscosity index, low pour point and thermal stability for demanding industrial applications.
3. For Surfactants & Defoamers: PPG is an intermediate for nonionic surfactants, emulsifiers and defoamer formulations, supporting foam control and emulsion stability in cleaning, textile and process industries.
4. For Metalworking & Functional Fluids: PPG is used in metalworking fluids, brake fluids and functional fluids, providing lubricity, corrosion protection and stable performance over a wide temperature range.
5. For Heat Transfer Fluids: With good thermal stability and low toxicity, PPG-based fluids are used as heat transfer media in industrial heating and cooling systems.
6. Consistent Quality For Global Industry: Supplied as high-purity viscous liquid in multiple molecular weight grades with consistent hydroxyl value and low water content, PPG gives polyurethane, lubricant, surfactant and fluid manufacturers a dependable polyether polyol with flexible packaging and stable supply.
