BLENDED FLUOROPOLYMER COMPOSITIONS

A blended fluoropolymer composition comprises a polytetrafluoroethylene (PTFE) having a first melt temperature (T m ) of 332° C or less, in the form of a liquid dispersion of particles having a mean particle size of 1.0 microns (µm) or less, said dispersion obtained via emulsion polymerization and w...

Beschreibung
Zusammenfassung:	A blended fluoropolymer composition comprises a polytetrafluoroethylene (PTFE) having a first melt temperature (T m ) of 332° C or less, in the form of a liquid dispersion of particles having a mean particle size of 1.0 microns (µm) or less, said dispersion obtained via emulsion polymerization and without being subjected to agglomeration, thermal degradation, or irradiation; and perfluoroalkoxy (PFA) in the form of a liquid dispersion of particles having a mean particle size of 1.0 microns (µm) or less, said composition having, based on the total solids of said PTFE and PFA, a PFA content of 50 wt.% to 60 wt.% and a PTFE content of 40 wt.% to 50 wt.%.
