PEG-PPG-PEG (Pluronic P123) symmetric triblock copolymer constitutes of poly(ethylene oxide)(PEO) and poly (propylene oxide) (PPO). The unique characteristic of PPO block exhibiting hydrophobicity at temperatures above 288K and solubility in water at temperatures below 288K lead to formation of micelle consisting of PEO-PPO-PEO triblock copolymers. Some studies report that the hydrophobic core contains PPO block and a hydrophilic corona is comprised of PEO block. In 30wt% aqueous solution Pluronic P123® forms a cubic gel phase.
Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.
PEG-PPG-PEG is used in the preparation and coating of Fe-W-C(O) nanoparticles by sol gel technique. Also, employed as sacrificial templates to prepare ZnS nanospheres, nanoporous silica.

Surface active material whose properties are dependent on the hydrophilic (EO)/hydrophobic (PO) ratio. High EO content gives better o/w stabilizers.
Terminal primary dihydroxy-functional oligomer.
