Abstract (en)

[origin: DE10004229A1] Process for working up aqueous dispersions of fluoropolymers. Fluoropolymer dispersions, in particular of fluoroelastomers, can be coagulated without adding chemicals, by compression with the aid of a gas and release through one or more small apertures.

[origin: DE10004229A1] Process for coagulating aqueous fluoropolymer dispersions comprises pressurizing the dispersion with a gas and expanding it through one or more small orifices.
