Abstract
A suspension of a particulate porous fluorinated resin in an aqueous medium containing a powder of an inorganic suspension stabilizer is heated approximately at a melting temperature of the resin whereby the resin is densified, the degree of densification of the resin depending on the heating temperature.
Claims8
A process for increasing the bulk density of a porous particulate fluorinated resin, which comprises preparing a suspension of a particulate porous fluorinated resin in an aqueous medium containing, as a suspension stabilizer, a powder of an inorganic material which is insoluble or slightly soluble in water, and heating the suspension at approximately the melting temperature of the resin, thereby reducing the volume of the particulate fluorinated resin.
