PLURONIC PE 6400 is a low-foaming, nonionic surfactant in the form of a block copolymer, with a central polypropylene glycol group flanked by two polyethylene glycol groups. It appears as a colorless, slightly cloudy liquid and is suitable for a wide range of applications. PLURONIC PE 6400 offers very high dispersing capacity for sparingly soluble calcium and magnesium salts and is also used in cutting and grinding fluids for metals, where it functions as a lubricant and coolant. Additionally, it serves as an emulsifier in polymerization processes.
