Chemical Name: Block Copolymer PF40
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 PF40 is resistant to water hardness salts and acids and alkalis in the concentrations normally used. This cloudy, colourless solution has good wetting and dispersing action coupled with low foaming tendency

Copolymer PF40 is dispatched in polyethylene or corrugated steel, galvanized or carbon steel drums. Copolymer PF40 is stable for 2 years when stored in the original sealed containers in a cool and dry place
Precautions for safe handling
Avoid contact with skin and eyes Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed. Normal measures for preventive fire protection
Conditions for safe storage
Keep container tightly closed in a dry and well-ventilated place
Inhalation:
May be harmful if inhaled. May cause respiratory tract irritation
Skin:
May be harmful if absorbed through skin. May cause skin irritation
Eyes:
May cause eye irritation
Ingestion:
May be harmful if swallowed
Copolymer PF40 is used as a low-foaming surfactant with very good dispersing action in detergents and cleaning agents. Typical application include rising aids, detergents for dishwashers and bottle-rinsing machines and industrial cleaning formulations. Copolymer PF40 is use3d as nonionic emulsifier for the emulsion polymerization of monomers like acrylates, styrene-acrylates and vinyl acetate. Nonionic and row foaming emulsifier in emulsion polymerization and as a dispersing agent for pigment pastes and preparations
- Styren/acrylate dispersions
- Acrylate dispersion
- Vinyl acetate dispersion
- Low foaming, nonionic surfactant and defoamer for use in detergents and cleaning agent
- Emulsifier, wetting and dispersing agent
- Low-foaming, nonionic surfactant for the chemical industry
