Fluoropolymer dispersion containing no or little low molecular weight fluorinated surfactant

Provides a fluorine-containing polymer dispersion of this invention claims a surface, preferably PTFE dispersion, wherein the dispersion comprising the average granularity of the waste water is 10 degrees centigrade at the nm fluorine-containing polymer particles, wherein the solid content of the dispersion is 35 to 70 wt.%. The dispersion does not contain the molecular weight is less than the 1000g/mol the surfactant is (scale low - molecular weight fluorocarbon surfactant or comprises a total solid by weight not more than 0.05 weight of the dispersion of the low - molecular weight the surfactant is as follows). The dispersion additionally comprises the non-fluorination nonionic surfactant or non-fluorination nonionic surfactant mixture and one or more non-fluorination anionic surfactant. Adjusting the non-fluorination's anionic surfactant, obtained at room temperature (e) with low viscosity dispersions. Having the dispersion comprising an aryl nonionic surfactant, which can environment-friendly, and obtainable by the coating of the easily into colour. Non-fluorination or non-ionic surfactant the content of for according to non-fluorination's and surfactant is selected, and fluorine-containing polymer dispersion and transition temperature in (A Batch according to truthfully of the discharge) is at least 26℃, preferably at least 28℃. Methods of the surface of the invention is the method of the dispersion.
