摘要:
Multilayered composite articles comprising a first layer comprising melt-extrudable perfluoropolymer, a second layer comprising a fluoropolymer derived from tetrafluoroethylene, at least one perfluorinated α-olefin; and vinylidene fluoride. The articles may be in the form of pipes, tubes, and hoses.
摘要:
A pipe or comprising a melt-mixed blend of polyamide and incompatible polyolefin and a compatibilizing agent where the polyamide exists as a discontinuous phase that is dispersed in a polyolefin matrix and wherein nanoclay is exfoliated in the polyamide phase. The pipe has enhanced resistance to the permeation of hydrocarbons relative to polyethylene. A method for making a pipe having enhanced resistance to the permeation of hydrocarbons.
