POLYMERIC PIPES AND LINERS AND FUEL LINES MADE FROM BLENDS OF FLUOROPOLYMERS AND POLYAMIDES |
摘要 |
<p>A pipe or liner for use in the oil and gas industry that comprises a melt-mixed bend of polyamide and grafted fluoropolymer having polar functionality where the grafted fluoropolymer having polar functionality exists as a discontinuous phase that is dispersed in a polyamide matrix. The pipe or liner has enhanced resistance to the permeation of hydrocarbons relative to polyethylene. A further embodiment is fuel lines that comprise a melt-mixed bland of polyamide and a grafted fluoropolymer having polar functionality.</p> |
