Polyether L-42 (Poloxamer 122), as a nonionic polyoxypropylene polyoxyethylene block copolymer, plays a key auxiliary role in multiple industrial fields due to its strong defoaming and foam suppression functions, excellent emulsifying, wetting, and dispersing capabilities, as well as outstanding acid-base stability.
It can quickly break foam under both dynamic and static conditions and effectively inhibit foam regeneration. At the same time, it has good biodegradability and environmental compatibility, making it a safe and mild multifunctional surfactant.
| Industry | Specific Process\/Application | Functional Role |
|---|---|---|
| Industrial and Household Cleaning | Low-foam hard surface cleaners, automatic spray cleaning, CIP in-place cleaning, high-pressure spray systems | Penetrate and remove oil, low foam easy to rinse, quick drying without residue |
| Dishwashing | Rinse aid for automatic dishwashers, quick drying of glass and ceramic ware | Reduce interfacial tension, accelerate water film leveling and evaporation, prevent water spots and stains |
| Metalworking | Cutting fluids, grinding fluids, metalworking lubrication and cooling fluids | Lubricate and cool, inhibit processing foam, prevent pump cavitation |
| Textile Printing and Dyeing | Pretreatment scouring, bleaching penetration, fiber wax removal and impurity removal | Promote uniform diffusion of alkali\/bleaching liquor, improve capillary effect and whiteness |
| Pesticide Formulations | Processing and dilution of emulsifiable concentrates, microemulsions, and suspensions | Emulsify and disperse active ingredients, enhance wetting, spreading, and adhesion of the spray liquid |
| Coatings\/Inks\/Adhesives | Pigment wetting and dispersion, defoaming during application | Reduce dynamic surface tension, improve color uniformity and adhesion |
| Defoamer Manufacturing | Core component of industrial defoamers for fermentation, papermaking, water treatment, etc. | Quick spreading and bubble breaking, long-lasting foam inhibition |
Polyether L-42 has a controllable molecular structure and exhibits good compatibility with anionic, cationic, and nonionic auxiliaries. It can be used as a primary surfactant or auxiliary defoaming component in low-foam cleaning formulations; in metalworking fluids, it is recommended to be used with extreme pressure additives to achieve optimal lubrication and cooling effects; in pesticide formulations, it is suitable for constructing emulsification and dispersion systems for high-concentration active ingredients.
