    摘要： Mixtures of fluoropolymer dispersions comprising: a) one or more dispersions constituted by TFE homopolymers or by its copolymers with particle average sizes ranging from 180 to 400 nm; b) one or more TFE copolymer dispersions with one or more monomers containing at least one ethylene unsaturation, the comonomer amount being such that the dispersion contains a number of fibrils lower than 10% of the total number of particles; said fibrils being polymer particles having a length/diameter (L/D) ratio higher than 5; the dispersion particle average sizes are smaller of about 90 nm; the component b) contains a comonomer amount such that the resulting polymer is not elastomeric and furthermore it shows composition and viscosity characteristics of the melt such as not to be thermoprocessable.
