摘要： A process for dispersion spinning non-melt-processible fluoropolymer fiber in which a mixture of an aqueous dispersion of non-melt-processible polytetrafluoroethylene or modified polytetrafluoroethylene fluoropolymer particles and an aqueous solution of matrix polymer is formed. The non melt-processible particles have an SSG of less than about 2.40. The aqueous dispersion contains an aliphatic alcohol ethoxylate nonionic surfactant having a 20% residuals temperature determined by thermogravimetric analysis (TGA) of less than about 290° C. and is essentially free of surfactants containing aromatic groups. The dispersion has a fluorinated surfactant content of less than about 300 ppm. The mixture is extruded into a coagulation bath containing a concentration of ions which coagulate the matrix polymer to form an intermediate fiber structure. The intermediate fiber structure is sintered to decompose the matrix polymer and coalesce. The present invention also provides a spinning composition useful for the dispersion spinning of non-melt-processible fluoropolymer fiber.

摘要： The present invention provides a process for making a filled fluoropolymer bearing comprising providing an aqueous fluoropolymer dispersion comprising fluoropolymer particles and anionic polyelectrolyte dispersing agent in an amount sufficient for stabilization. The dispersion contains less than about 300 ppm fluorosurfactant based on the weight of the dispersion. The dispersion is coagulated to make a mush and a bearing filler is added to the dispersion prior to or after making the mush. The mush containing bearing filler is applied onto a bearing substrate to produce a coated substrate which is sintered and formed into a bearing.
