Chemical Name: Block Copolymer PF20
Grade: Chemical
Low Foaming Surfactants
Block Copolymer EO-PO I.C.C
manufactures a wide range of low foaming surfactants designed to provide the appropriate functionality for all of our customers application needs. We help you to get your foam under control. Alkyl based EO-PO block copolymers typically have lower surface tensions, CMC and greater dispersing power compared to the corresponding simple alkyl ethoxylates. The propylene oxide block acts as a branched residue within the copolymers leading to performance advantages like better solubilization and emulsification properties. Copolymer PF20 can be used in combination with other nonionic, anionic and cationic surfactants. Copolymer PF20 is resistant to water hardness salts and to acids and alkalis in the concentrations normally used. Preliminary tests are required

Copolymer PF20 is used as a low-foaming surfactant and defoamer in detergents and cleaning agents. Copolymer PF20 has good wetting and dispersing action coupled with low foaming tendency. Within the Copolymer PF series, the products with a lower degree of ethoxylation have a better foam-suppressing effect than the products with a higher degree of ethoxylation. Typical applications include rinsing aids, detergents for dishwashers and bottle-rinsing machines and industrial cleaning formulations. Copolymer PF20 is also used as a low-foaming emulsifier in emulsion polymerization and as a dispersing agent for pigment pastes and preparations. Copolymer PF20 applications include reactions in the chemical industry. Copolymer PF20 is used as a low foaming wetting agent in aqueous coatings. Copolymer PF20 is used as a low foaming emulsifier in emulsion polymerization to improve the emulsion stability and prevents foam during spray drying of dispersion powders
