Polypropylene glycol or polypropylene oxide is the polymer of propylene glycol. Chemically it is a polyether. The term polypropylene glycol or PPG is reserved for low to medium range molar mass polymer when the nature of the end-group, which is usually a hydroxyl group, still matters. The term “oxide” is used for high molar mass polymer when end-groups no longer affect polymer properties. In 2003, 60% of the annual production of propylene oxide of 6.6×106 tonnes was converted into the polymer.

Properties
PPG has many properties in common with polyethylene glycol. The polymer is a liquid at room temperature. Solubility in water decreases rapidly with increasing molar mass. Secondary hydroxyl groups in PPG are less reactive than primary hydroxyl groups in polyethylene glycol. PPG is less toxic than PEG, so biotechnologicals are now produced in PPG.

Uses
PPG is used in many formulations for polyurethanes. It is used as a rheology modifier.
PPG is used as a surfactant, wetting agent, dispersant in leather finishing.
PPG is also employed as a tuning reference and calibrant in mass spectrometry.
PPG is used as a primary ingredient in the manufacture of paintballs.

Polypropylene glycols are polymers of propylene oxide. They are clear, viscous liquids with low pour points. Viscosity increases and water solubility decreases with increasing molecular weight.

Uses: PPGs are used as additives in metal-working fluids , as plasticizers , antifoaming agents, as additives in the rubber and paint industries , as starting materials for the synthesis of urethane foams and resins, surfactants, polypropylene ethers and esters ; PPGs with molecular weights above 1200 are used in the production of cosmetic preparations

Chemical Properties
Viscous colourless liquid (whose viscosity depends upon the average
Definition
ChEBI: A macromolecule composed of repeating propyleneoxy units.
General Description
Colorless liquid that is odorless or has a mild sweet odor. May float or sink in water.
Reactivity Profile
Poly(propylene glycol) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Health Hazard
The compound has a very low toxicity; few, if any, symptoms will be observed. Contact of liquid with eyes causes slight transient pain and irritation similar to that caused by a mild soap

Polipropilen glikol veya polipropilen oksit, propilen glikolün polimeridir. Kimyasal olarak bir polieterdir. Polipropilen glikol veya PPG terimi, genellikle bir hidroksil grubu olan uç grubun doas hala önemli olduu zaman, düük ila orta molar kütle polimerleri için ayrlmtr. “Oksit” terimi, uç gruplar artk polimer özelliklerini etkilemediinde yüksek molar kütle polimeri için kullanlr. 2003 ylnda, yllk 6.6 × 106 ton propilen oksit üretiminin% 60′ polimer haline dönütürülmütür.
