摘要

Dispersion powder, fluoropolu00ecmero, composition of coating, coated substrate, the film self sustainable and batch process.Aqueous dispersion of non melt processable fluoropolymer, process of its manufacture and concentrated dispersion and powder obtained from the dispersion.The particles of fluoropolymers of dispersion have specific gravity standard (SSG) of less than 2.225 and comprise a core of high molecular weight polytetrafluoroethylene and polytetrafluoroethylene or modified polytetrafluoroethylene coverage of lower molecular weight.At least about 1.5% by weight of the fluoropolymer particles comprise particles substantially in the form of a rod holding ratio between length and diameter of more than about 5.
