Name: Perfluoropolyether carboxylic Ammonium; PFPE-NH4
CAS number: ND
Molecular formula:[CF(CF3)CF2O]n-COO-NH4
Appearance: Room temperature, high concentration anhydrous state is colorless to light yellow waxy solid; The dilution state is colorless or light-colored two-phase liquid, which is heated to about 40 ° C and stirred into single-phase clarified liquid.
Solid content: 98%; 50%; 10%
Critical micelle concentration CMC%: ＜2, @25 ° C
Product characteristics: ionic fluoride surfactant, with strong ability to reduce surface tension, excellent chemical stability and thermal stability, excellent biodegradability, low toxicity. It can be used in coating inks, polymer emulsifiers, plastic/rubber processing, cleaning agents and other fields, and can replace directly connected branched-perfluorinated carboxylate (PFOA).
* Emulsification (halogenated raw materials) : highly effective, recommended for the emulsification of fluorocarbons.
* Wettability: Highly effective.
* Washability: medium effective.
* Dispersibility (halogenated raw materials) : highly effective, recommended for the dispersion of fluorocarbon powder.
* Compatibility: Can be used for a wide PH range, but only low concentration polyvalent cation soft water system.
Product use:
* Foamability: in the water-based system, the initial foam is more, the foam stability is good, and the oxidant is stable (such as chromic acid, peroxide and other oxidants).
* Polymer: In the polymerization reaction of fluorocarbon monomers (such as tetrafluoroethylene PTFE, vinylidene fluoride PVDF, etc.) can be used as a good emulsifier.
Adhesive: Significantly enhance wetting and leveling properties, improve product penetration and adhesion, compatible with most water-based formulations.
* Cleaning agent: can be effectively used for hair care and hard surface cleaning agent, enhance wetting ability, improve cleaning effect.
