| Pluronic P75 |
 |
PLURONIC nonionic surfactants are block copolymers of propylene oxide and ethylene oxide. The propylene oxide block is sandwiched between two ethylene oxide blocks.
PLURONIC surfactants: - are better emulsifiers, are better dispersants, - cover a broader range of molecular weights, - are terminated by primary hydroxyl groups (higher reactivity and acidity).
Wetting agent, emulsifier, demulsifier, viscosity control agent, dispersant, antistat agent, lubricant - agricultural, cosmetics, metal cleaning, paper, textile, paints. |
