Description

Polypropylene Glycol n-Ethylperfluorooctanesulfonamide is a fluorinated surfactant and surface modifier that combines the hydrophobic and oleophobic properties of perfluorinated chains with the hydrophilic nature of polypropylene glycol. This unique structure makes it a highly effective agent for reducing surface tension and imparting water, oil, and stain repellency. It is primarily utilized in industries requiring advanced surface engineering and durable performance coatings. The compound is registered under CAS No. 37338-48-0.

Application

• Fluorinated Surfactant: Used as a key additive in fire-fighting foams (AFFF) and specialty coatings to enhance spreading and film-forming properties.
• Surface Modifier for Polymers: Imparts oil and water repellency to textiles, carpets, and non-woven fabrics for protective apparel and upholstery.
• Additive for Lubricants and Greases: Enhances the performance and stability of high-temperature and specialty lubricants.
• Paper and Packaging Coatings: Provides grease and moisture resistance for food packaging and industrial papers.
• Electronics and Semiconductor Industry: Used in photoresist formulations and as a surfactant in etching and cleaning solutions.
• Personal Care and Cosmetics: Acts as a conditioning agent and water repellent in specific high-performance cosmetic formulations.

Quality Control

Our Polypropylene Glycol n-Ethylperfluorooctanesulfonamide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and functional property verification, to ensure consistent performance and reliable supply. Certificates of Analysis (COA) documenting purity, fluorine content, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids, strong bases, and strong oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
