General description

Pluronic® F108 is a tri block copolymer and a terminal primary dihydroxy-functional oligomer. It behaves as a nonionic surfactant. It is a surface active material whose properties are dependent on the hydrophilic (EO)/hydrophobic (PO) ratio. High EO content gives better o/w stabilizers.

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.
Pluronic® F108 was used as a surfactant in a medium to prevent the cells from sticking to the surface of a microfluidic device.{7}-{11}Pluronic may be potentially useful as a pathogen detector. It was used in the analysis of microbial community and genotyping single nucleotide polymorphisms (SNPs).{9} The triblock copolymer was used as a pore template for the fabrication of porous carbons and carbon/silica composite.{10}

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.
