Thermally processed fluoroplast powders (ПФТ) (technical specification 301-05-25) are used as fillers for lubricants. ПФТ-6000 is used as a filler in fractionating columns and filtering apparatuses operating in aggressive media and as an inert filler in fluidized bed driers. Thermally processed fluoroplast powder is obtained by means of grinding of fluoroplast-4 and fluoroplast-4A wastes. Depending on the extent of grinding, powders of the following fractions are available: ПФТ-6000, ПФТ-500, ПФТ-400, ПФТ-300 and ПФТ-200.
