Product Name:Polypropylene Glycol (PPG)
English Name:Polypropylene Glycol (PPG)
CAS No.:25322-69-4
Aliases:PPG, Poly(propylene glycol)
Molecular Formula:H-(C3H6O)n-OH
Physical Properties:Colorless to slightly yellow transparent viscous liquid with a slight characteristic odor. Relative density approximately 1.0-1.03 g/cm³ depending on molecular weight; open-cup flash point above 200 °C; low-molecular-weight grades are soluble in water, and solubility decreases with increasing molecular weight; soluble in ethanol, acetone, benzene and other organic solvents.
Uses:Polypropylene glycol is a polyether polyol commonly used in the polyurethane industry for producing elastomers, foams, adhesives and sealants. It is also used as a component in lubricants, hydraulic fluids, antifreeze, compressor oils and heat-transfer fluids. In personal care products such as shampoos, conditioners and shaving creams, it acts as a softening and conditioning agent, and is widely applied in resins, inks, coatings and metalworking fluids.
Technical Specifications:
Appearance: colorless to slightly yellow transparent viscous liquid with a slight characteristic odor
Hydroxyl value: 12-623 mg KOH/g (grade-dependent, PPG200-PPG8000)
Average molecular weight: 180-8800 (PPG200-PPG8000)
Water content: ≤0.5%
Acid value: ≤0.5 mg KOH/g; color: ≤80 Pt-Co (reference values for PPG200)
