摘要： Blended fluoropolymer compositions are provided. In one embodiment, a liquid dispersion of a first fluoropolymer is blended with a liquid dispersion of a second fluoropolymer. The first fluoropolymer may be polytetrafluoroethylene (PTFE), such as a low molecular weight PTFE (LPTFE) that has been polymerized via a dispersion or emulsion polymerization process, and which has not been agglomerated, irradiated, or thermally degraded. The LPTFE may be in the form of an aqueous dispersion, having a mean particle size of less than 1.0 microns (μm), with the LPTFE having a first melt temperature (Tm) of 332° C. or less. The second fluoropolymer may be a melt processable fluoropolymer (MPF), such as fluorinated ethylene propylene (FEP), in the form of an aqueous dispersion, and having a mean particle size of less than 1.0 microns (μm). Blending of the dispersions facilitates interaction of the LPTFE and MPF on a submicron level to facilitate intimate blending such that, when the blended fluoropolymer composition is dried, a crystal structure representing a true alloy of the fluoropolymers is formed, having melt characteristics that differ from those of the individual fluoropolymers. The blended fluoropolymer composition may be used to provide a coating having improved impermeability, stain resistance, abrasion resistance, smoothness, and higher contact angles.

摘要： Blended fluoropolymer compositions that, in one exemplary application, may be applied as a coating to a flexible substrate and, optionally, to a flexible substrate that has been previously coated with a primer or basecoat and/or a midcoat. In one embodiment, the composition is a blend of at least one low molecular weight polytetrafluoroethyelene (LPTFE) and at least one melt-processible fluoropolymer (MPF). In another embodiment, the composition includes a fluoropolymer base component including at least one fluoropolymer such as high molecular weight polytetrafluoroethylene (HPTFE), and additionally includes the LPTFE/MPF blended fluoropolymer composition. After being applied to the flexible substrate, optionally over a primer or basecoat and/or midcoat, and then cured, the present compositions form coatings that demonstrate improved abrasion resistance and/or improved release characteristics and/or increased translucency/transparency and/or improved impermeability. The present compositions may also be used to produce films having a high degree of clarity and impermeability. The present compositions in powder form may be melt or paste extruded to form articles with improved impermeability.
