AN EXTRUSION DIE, METHODS OF COATING A WIRE CORE, AND A COATED WIRE BY THE EXTRUSION DIE AND METHODS

摘要

This disclosure relates to a coated wire, an extrusion die, a process of coating a wire and a method of testing wrinkles on covering of a coated wire. A coated wire comprises a wire core (2); and a covering (4) comprising a thermoplastic composition which comprises by weight of total composition, (i) 10% to 50% of a poly(arylene ether); (ii) 5% to 25% of a polyolefm; and (iii) 15% to 45% of an impact modifier. The wrinkles presented on the covering (4) of a coated wire manufactured by an extrusion die are substantively reduced.
