Process for coating a wire or cable with polyphenylene sulfide alloy and resulting coated wire |
摘要 |
The present invention relates a process for manufacturing polymer coated wire and cable and an electrically conductive wire having a metal core and an outer electrically-insulative, polymer coating capable of withstanding temperatures as high as 150° C., wherein the polymer composition contains polyphenylene sulfide, a polymeric grafting agent and an ethylene copolymer. The polymeric grafting agent is a copolymer of at least about 50% by weight ethylene, about 0.5% to about 15% by weight of a reactive comonomer (e.g. unsaturated epoxide of 4-11 carbon atoms) and the ethylene copolymer comprises at least about 50% by weight ethylene and about 1% to about 35% by weight of an acid-containing unsaturated mono-carboxylic acid comonomer. The molar ratio of the reactive comonomer in the polymeric grafting agent to the unsaturated mono-carboxylic acid comonomer of the ethylene copolymer is to be maintained between 1.0 and 5.5 in order to achieve the desired polyphenylene sulfide wire coating properties.
