The invention relates to very high melt flow fluoropolymer compositions, having low melt viscosities. The fluoropolymers have low molecular weights of from 5 kDa to 200 kDa and melt viscosities of less than 2 kilopoise (kP) at 232° C. and 100 s−1. One use for the high melt flow fluoropolymers is in the formation of very small diameters fibers, useful for melt-blown non-woven materials. Fiber diameters of less than 9 microns, and preferably 500 to 2000 nm can be produced.
