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.

摘要:
A siphon tube having a polymeric material into which at least one continuous reinforcing agent is embedded, and wherein the at least one reinforcing agent runs substantially the length of the siphon tube. The polymer material can be one or more polymers selected from one or more high density polyethylenes, one or more polyamides, and one or more fluoropolymers.
摘要:
A process for producing plasticized polyamide blends containing additives such as tougheners, reinforcing agents, and/or filler. High average molecular weight plasticized blends containing additives may be made using the process of the invention. Pipes and tubing may be made from the blends prepared using the process of the invention.
摘要:
Polyamides made from 1,6-hexanediamine, and the dicarboxylic acids 1,10-decandioic acid and/or 1,12-dodecanedioic acid, and terephthalic acid in specified proportions are particularly resistant to salt stressed (induced) corrosion cracking. This makes them particularly useful as vehicular parts which may be exposed to salts. Particularly when these polyamides contain tougheners and/or plasticizers they are especially useful for hoses and tubes.
摘要:
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.
摘要:
The present invention relates to a pipe, especially an oil pipe, having a lining comprising a fluoropolymer adhered to its interior surface and a lining formed on its exterior surface. The interior and/or exterior lining may comprise a primer layer comprising a fluoropolymer, and preferably a perfluoropolymer and an overcoat or a preformed film adhered to the primer layer. Either the overcoat or the preformed liner also comprises a fluoropolymer, and preferably a perfluoropolymer. The surface of the lining facing the flowable media, such as oil, may be a pure perfluoropolymer to provide a particularly good non-stick surface for the oil.
