Polyether L-44 is mainly used in four major industrial fields: polyurethane industry, industrial cleaning and metalworking, agrochemical formulations, and personal care products.
Detailed Application Industries and Processes
1. Polyurethane Industry
- Foam Systems: As an efficient foam stabilizer, widely used in flexible, rigid, and semi-rigid foam formulations, providing emulsification, nucleation, and cell size refinement functions to ensure uniform and stable foam.
- Coatings, Adhesives, and Elastomers: Acts as a leveling agent and wetting agent, improving system surface tension and substrate wettability, reducing surface defects such as craters and orange peel.
2. Industrial Cleaning and Metalworking Fluids
- Industrial Cleaning: Used as a low-foaming surfactant in industrial cleaning formulations, suitable for high-pressure spraying and circulating cleaning processes, providing synergistic effects of emulsification, detergency, and rust prevention.
- Metalworking Fluids: Provides lubrication, wetting, and cleaning effects, helping to extend tool life and improve workpiece surface quality.
3. Agrochemical Formulations
- Used as a pesticide emulsifier to improve the emulsion stability and dilution dispersibility of formulations such as emulsifiable concentrates and microemulsions, enhancing wetting and spreading ability of the spray liquid, thus improving efficacy utilization.
4. Personal Care Products
- Used as a mild emollient in cosmetic formulations, providing a smooth skin feel and improving skin feel and spreadability. Low skin irritation, non-allergenic, and good biocompatibility.
Core Process Characteristics
| Characteristic | Process Value |
|---|
| Excellent emulsifying performance | Outstanding emulsification effect for various oil phase systems, resulting in stable and fine emulsions |
| Low-foaming property | Low foam volume and rapid defoaming, suitable for industrial operation environments such as high-pressure spraying and agitation where excessive foam is undesirable |
| Good wetting and dispersibility | Quickly wets solid surfaces, effectively disperses particles, and enhances system uniformity |
| Strong chemical stability | Maintains stable performance in acid, alkali, and hard water systems, not prone to failure |
| Multifunctional compatibility | Can be well compounded with anionic, cationic, and other nonionic surfactants |
