Abstract:
1. Mixtures of fluoropolymer dispersion, wherein: a) a dispersion is formed by tetrafluoroethylene (TFE) homopolymers or by its copolymers with one or more monomers containing at least one unsaturation of ethylene type in amounts from 0 up to 8% by weight the average particle size ranges from 190 to 400 nm; b) another dispersion is selected from one or more of the following: the average particle size of the b) dispersion ranges from 20 to 60 nm; the ratio between the average particle sizes of the dispersion b) with those of the dispersion a) being less than 0.3, component b) being obtainable by microemulsion polymerization.
