摘要： 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° C.
