General description

Pluronic® L-81 is a lipoprotein secretion inhibitor.

Application

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.
Binary mixtures of Pluronic®  L-81 with Pluronic F-127 to form binary hydrogels.{12}

Packaging

250 mL in poly bottle

Features and Benefits

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

Physical form

Terminal primary dihydroxy-functional oligomer.
