Fluoropolymer dispersions

摘要

Mixtures of fluoropolymer dispersion, wherein:a) a dispersion is formed by TFE (co)polymers with average particle sizes in the range 180-400 nm;b) another dispersion selected from:1) (co)polymer dispersion of TFE;2) thermoplastic copolymers of TFE;the average particle sizes of dispersion b) range from 20 to 60 nm;the ratio between the particle sizes of dispersion b) compared with those of dispersion a) is lower than 0.3.
