Product description:
Polyoxyethylene-polyoxypropylene block copolymer L-61 is a block polyether, belonging to non-ionic surfactants, mainly composed of polyoxyethylene and polyoxypropylene block polymers. It appears as a colorless and transparent liquid with cloud point characteristics (solubility changes at specific temperatures). It is used as an defoamer in industries such as papermaking and fermentation. Its characteristics include non toxicity, good dispersibility, high thermal stability, and good chemical stability. It is suitable for preparing low foaming detergents or as a universal defoamer.
Product applications：
Propylene glycol block polyether(Surfactant L-61/L-62/L-64) is a colorless transparent liquid to white paste, which appears as a white solid as the molecular weight increases. Nonionic surfactants defoaming that can be used as a stain remover, etc. Widely used in industrial cleaning, home cleaning, electronics industry and other fields, it can be used as a lubricant and coolant for metal processing. When used as a stain remover, it is applied to tableware, video beverage bottles, and other fields. In the pharmaceutical industry, it is used as a drug solubilization and sustained-release carrier. In the daily chemical industry, it is used as emulsifier and wetting agent (shampoo, lotion, etc.). In industry, it is mainly used as a defoamer, dispersant, and lubricant additive. Propylene glycol block polyether(Surfactant L-61/L-62/L-64) known as nonionic surfactants DEFOAMING/low foaming agent in widely industrial. it can be used as wetting agent or cleaning agent.
