Perfluorohexylethyl amphoteric surfactants integrate the superior properties of fluorinated surfactants and betaine surfactants. The perfluorohexylethyl group in its molecular structure endows the product with extremely low surface tension, excellent heat resistance, chemical stability and weather resistance. Meanwhile, the betaine structure ensures good compatibility, low irritation and biocompatibility. Free of PFOA and PFOS, this product features high environmental friendliness. Thanks to the above characteristics, such surfactants have been widely applied in industries including industrial manufacturing, fire protection, new materials and daily chemicals.

 

 

 

As a key raw material for eco-friendly foam fire extinguishing agents, perfluorohexylethyl amphoteric surfactants possess outstanding surface activity and foaming stability. They can effectively reduce the surface tension of aqueous solutions and rapidly form a dense and stable foam layer covering the surface of combustibles, achieving oxygen isolation, cooling and fire suppression. They are especially suitable for difficult-to-control fires such as oil fires and organic solvent fires.

 

In practical application, this type of surfactant can be compounded with other ingredients to prepare multiple high-performance foam extinguishing agents. For instance, as a fire-extinguishing emulsifier, it can be blended with ammonium polyphosphate, xanthan gum and ethylene glycol to produce eco-friendly water-based fire extinguishing agents that meet storage and usage requirements under high temperature (+63℃) and low temperature (-42℃), featuring high efficiency, cold resistance and environmental protection. It can also be compounded with sodium methyl cocoyl taurate, anti-burning agents and silicone-containing surfactants to develop low-temperature resistant, seawater-resistant and high-multiple miscible foam extinguishing agents. The foaming multiple can reach 14.7, and the 25% drainage time is up to 19.4 minutes. Its fire extinguishing efficiency and anti-burning performance are significantly better than traditional extinguishing agents. With simple preparation processes and low cost, it is convenient for large-scale industrial production.

 

In addition, it can replace restricted perfluorooctane sulfonates in the production of aqueous film-forming foam agents. The surface tension of its 0.1% aqueous solution can be as low as 13.58 mN/m. With superior fire extinguishing and anti-burning properties compared with traditional components, it serves as an essential option for the green upgrading of the fire protection industry.

 

 

Relying on excellent surface activity, permeability and chemical resistance, perfluorohexylethyl amphoteric surfactants are widely used in various industrial cleaning scenarios, especially for occasions requiring high cleaning precision and anti-corrosion performance. They can efficiently remove oil stains, dirt, dust and other impurities without damaging the cleaned substrates.

 

In the field of metal cleaning, it can be used as a core component to formulate water-based cleaning agents for ferrous metals, with a typical dosage of 0.01～0.5% by mass. When compounded with sodium dodecyl benzene sulfonate and fatty alcohol polyoxyethylene ether sulfate, the cleaning efficiency can reach 90%. It maintains stable properties, causes no corrosion to metal substrates, and reduces the total dosage of surfactants for better environmental performance.

 

In electronic cleaning, it is applicable to precision electronic components such as semiconductors and circuit boards. Its ultra-low surface tension enables penetration into tiny gaps of components to efficiently remove residual contaminants including photoresist and flux. With good insulation and chemical stability, it will not impair the performance of electronic components.

 

Furthermore, it is suitable for cleaning industrial equipment, pipelines and floors with both decontamination and anti-scaling effects. It exhibits great compatibility with other ionic and amphoteric surfactants, and the compound ratio can be adjusted according to cleaning demands to adapt to diverse application scenarios.

 

 

In the material and coating sector, perfluorohexylethyl amphoteric surfactants are mainly used as emulsifiers, dispersants and modifiers. They can significantly improve the stability, water resistance, weather resistance and surface properties of products, and are widely adopted in the production of latex paint, alkyd emulsion, printing ink, polymer emulsion and other products.

 

In the preparation of coatings and emulsions, it acts as a high-efficiency emulsifier to effectively reduce oil-water interfacial tension, form a uniform and stable system, and avoid delamination and demulsification. It also improves the leveling and adhesion of coatings, forming smooth and compact coating surfaces with enhanced water and stain resistance.

 

In the ink industry, it functions as a dispersant and wetting agent to optimize the dispersion of pigments and fillers, prevent pigment agglomeration, and improve printability for clearer and brighter printed patterns. Meanwhile, it strengthens the water resistance and friction resistance of ink.

 

Moreover, it can be used as a modifier and stabilizer for polymers to prepare high-performance polymer emulsions with upgraded weather resistance, water resistance and chemical resistance. It also serves as a release agent and lubricant in polymer processing, reducing friction coefficient during production, boosting efficiency and improving surface finish of finished products.
