Polyether F-38 (Poloxamer 108) is a nonionic block copolymer surfactant, which is used as a key functional component in many industrial fields due to its excellent emulsifying, wetting, dispersing capabilities and low foam characteristics.
| Application Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Polyurethane Industry | Synthesis of flexible foam, rigid foam, semi-rigid foam, and elastomers | Core reaction component, regulating cell structure and reaction progress |
| Defoamers and Demulsifiers | Synthesis of high-efficiency defoamers and crude oil demulsifiers | Synthesis intermediate, utilizing hydrophilic-lipophilic balance capability |
| Coatings and Adhesives | Modification of polyurethane coatings, adhesives, and cast elastomers | Modifying component, improving flexibility, hydrolysis resistance, and low-temperature impact resistance |
| Textile Auxiliaries | Spinning oils, dyeing auxiliaries, finishing agents | Leveling agent, antistatic agent, improving hydrophilic hand feel |
| Paper Chemicals | Pulp dispersion, paper surface treatment | Improving pulp dispersibility and paper surface properties |
| Metalworking Fluids | Cutting fluid, lubricant formulations | Providing lubrication, rust prevention, cleaning, and cooling functions |
Polyether F-38 remains chemically stable in acidic, alkaline, and high-hardness water conditions, with low foam generation, making it suitable for process scenarios requiring low foam or rapid defoaming. Its characteristics of low toxicity, no skin irritation, and easy biodegradation (OECD 301B, >60%) meet the requirements of modern industrial green development.
