Abstract
A fluorocarbon composite is provided for use as liners and particularly for use as wire insulation and in extruded tubing for push-pull cable assemblies. The composite has excellent anti-friction and abrasion-resistant properties and can be utilized in environments requiring operation over a wide range of temperatures and load conditions, including high temperature applications. The composition comprises a mixture of a polymer of tetrafluoroethylene and a polymer of arylene sulfide, which mixture may also include a filler.
Claims21
An extruded tubular product consisting essentially of a mixture of a resin of fluorocarbon polymers and a polymer of arylene sulfide in the range of from about 5 to 25 weight parts per hundred resin.
An extruded tubular product consisting essentially of a mixture of a resin of polytetrafluoroethylene and a polymer of about 18 parts per hundred resin of polyphenylene sulfide.
An extruded tubular product consisting essentially of a mixture of a resin of fluorocarbon polymers, a polymer of arylene sulfide of from about 5 to 25 weight parts per hundred resin and a filler wherein said combined mixture of said filler and arylene sulfide is less than about 30 parts per hundred resin.
An extruded tubular product consisting essentially of a mixture of a resin of fluorocarbon polymers, a polymer of arylene sulfide and a filler wherein said filler and arylene sulfide are in amounts within and including the area defined by points ACDF as depicted in FIG. 2.
An extruded tubular product consisting essentially of a mixture of a resin of fluorocarbon polymers, a polymer of arylene sulfide in the range of from about 10 to 13 weight parts per hundred resin, and a filler in the range of from about 5 to 8 weight parts per hundred resin.
An extruded tubular product consisting essentially of a mixture of a resin of fluorocarbon polymers, a polymer of arylene sulfide, and a filler, wherein said extruded tubular product further comprises an additive in the form of a lubricating fluid which is applied to the wearing surfaces of said extruded tubular product, said arylene sulfide and filler being in amounts within and including the area as defined by the points GHIJ as depicted in FIG. 2.
