A composition for manufacturing a crosslinked ethylene tetrafluoroethylene (ETFE) copolymer with enhanced abrasion resistance and heat resistance is provided, the composition including ETFE, about 0.1-10% w/w of a metal oxide that effectively scavenges high levels of fluoride ions; and a crosslinking agent. Methods of using and making the composition are also provided.

An FEP pellet having a volatile content of 0.2% by weight or less. The FEP pellet satisfies the following requirements (i) and (ii) when used to form a insulating material coating a core wire by extrusion coating at a coating speed of 2,800 ft/min.: (i) an adhesive strength between the insulating material and said core wire of 0.8 kg or more; and (ii) an average number of cone-breaks in the insulating material of one or less per 50,000 feet of the coated core wire.

FEP pellet

A fluorine-containing copolymer obtained by copolymerizing tetrafluoroethylene, hexafluoropropylene and perfluoro vinyl ether as component monomers, wherein a weight ratio of tetrafluoroethylene, hexafluoropropylene and perfluoro vinyl ether units constituting the fluorine-containing copolymer is 70 to 95: 5 to 20: 0 to 10, respectively; the fluorine-containing copolymer having: a melt flow rate of 30 (g/10 minutes) or more; a volatile content index of 0.2% by weight or less; and a stress relaxation modulus G(t) (unit: dyn/cm) which satisfies the following formula at t=0.1 second when measured at a temperature of 310&#xb0; C.:(0.1)&#x3e;7&#xd7;10&#xd7;X&#x2212;3000where X denotes the melt flow rate (unit: g/10 minutes). Also disclosed is an insulating material composed of the fluorine-containing copolymer and an insulated cable having a core conductor coated with the fluorine-containing copolymer.
