Beschreibung
Zusammenfassung:	This invention relates to composites of fluorocarbon polymers, preferably polytetrafluoroethylene, which contain less than about 23% by weight polyamide-imide resin. More particularly, this invention relates to extrudable polytetrafluoroethylene composites which exhibit improved abrasion and friction resistance and other improved properties over a wide range of temperature and load conditions, and which are particularly adaptable for use as liners in wire insulation and in push-pull cable assemblies. MATERIALES COMPUESTOS DE POLIMEROS DE HIDROCARBUROS FLUORADOS, RESISTENTES A LA ABRASION, PRODUCTO TUBULAR EXTRUIDO Y MONTAJE DE CABLE DE VAIVEN, SIENDO LOS HIDROCARBUROS FLUORADOS, PREFERIBLEMENTE, POLITETRAFLUOREOETILENO, Y CONTENIENDO MENOS DE ALREDEDOR DE 23% EN PESO DE RESINA DE POLIAMIDA-IMIDA. MAS PARTICULARMENTE, ESTA INVENCION SE REFIERE A MATERIALES COMPUESTOS DE POLITETRAFLUOROETILENO EXTRUIBLES QUE TIENEN UNA MEJOR RESISTENCIA A LA ABRASION Y LA FRICCION, Y OTRAS PROPIEDADES MEJORADAS, EN UN AMPLIO INTERVALO DE CONDICIONES DE TEMPERATURA Y CARGA, Y QUE SON PARTICULARMENTE ADAPTABLES PARA USO COMO REVESTIMIENTO O FORRO EN AISLAMIENTO DE ALAMBRES Y EN MONTAJES DE CABLES DE VAIVEN.
