An insulated conduit for use in offshore, deep water environments includes a pipe and a fluoropolymer composition. The pipe has an outer surface with the fluoropolymer composition disposed about the outer surface of the pipe for providing a thermal insulation layer. The fluoropolymer composition includes a fluoroplastic polymer present in an amount of at least 50 parts by weight based on 100 parts by weight of the fluoropolymer composition. The fluoropolymer composition also includes a fluoroelastomer present in an amount of a fluoroelastomer present in an amount of from about 20 to about 50 parts by weight based on 100 parts by weight of the fluoropolymer composition. The fluoropolymer composition has a thermal conductivity less than about 0.20 W/mK at 205&#xb0; C.

A micropowder composition containing a granular PTFE micropowder, a fine powder PTFE micropowder, and a fine powder molding resin provides mixtures with fluoroelastomers containing copolymerized and alternating units of tetrafluoroethylene and propylene that provide molded articles having improved surface smoothness characteristics and tear resistance on molding. Processes for mixing additives with fluoroelastomers by adding or mixing the fluoroelastomer with the additives in the presence of micropowder PTFE compositions.
