摘要:
The disclosure of this application is directed to a water-curable composition comprising a water-curable, silane modified alkylene-alkyl acrylate copolymer, a mineral filler and a halogenated flame retardant additive. These compositions are useful as extrudates about wires and cables providing insulation or jacketing thereon characterized by resistance to deformation and by flame retardancy.

The disclosure of this application is directed to a composition of a copolymer of an alkylene-alkyl acrylate, a talc filler coated with a metal salt of a fatty acid and a non-polar flame retardant additive. The compositions of this invention are useful as insulation about electrical conductors, providing insulated electrical conductors which have improved flame retardant properties and improved insulation resistance.
摘要:
A composition for electrical applications having good electrical resistance, tensile strength and elongation consisting essentially of:(a) ethylene polymer, and(b) at least 10 parts by weight of talc filler per 100 parts by weight of ethylene polymer, said talc filler coated with at least one metallic salt of a fatty acid having 8 to 20 carbon atoms.
摘要:
An article of manufacture comprising, as a first component, a plurality of electrical conductors, each surrounded by one or more layers of a mixture comprising one or more polyolefins and the reaction product of a compound containing a sterically hindered amine or phenol and a quinone compound, and, as a second component, hydrocarbon cable filler grease within the interstices between said surrounded conductors.
摘要:
A process for crosslinking a thermoplastic ethylene silane copolymer which comprises forming the ethylene silane copolymer in a thermoforming operation into a shaped article and thereafter subjecting the thermoplastic ethylene silane copolymer shaped article to a solution of benzoic acid in an mount and for a time sufficient to crosslink the thermoplastic ethylene silane copolymer.
摘要:
A composition comprising:(a) polyethylene having a density equal to or less than 0.925 gram per cubic centimeter, grafted with an unsaturated aliphatic diacid anhydride; and(b) magnesium hydroxide, surface treated with a saturated or unsaturated carboxylic acid or a metal salt thereof in an amount of about 0.1 to about 1 part by weight of acid or salt per 100 parts by weight of magnesium hydroxide.
摘要:
A composition useful in the manufacture of cable comprising:(i) a copolymer comprised of ethylene and vinyl acetate;(ii) a surface treated magnesium hydroxide having (a) a strain in the direction of not more than 3.0.times.10.sup.-3 ; (b) a crystallite size in the direction of more than 800 angstroms; and (c) a surface area, determined by the BET method, of less than 20 square meters per gram; and(iii) a silicone fluid.
摘要:
A composition useful in the manufacture of cable comprising:(i) a crosslinkable thermoplastic resin;(ii) a metal hydrate flame retardant compound;(iii) an organic peroxide crosslinking compound, which decomposes at a temperature of at least about 140.degree. C., but below the decomposition temperature of the polymer; and(iv) an unsaturated silicone fluid.

摘要:
Compositions of relatively water-stable thermoplastic polymers having hydrolyzable, pendant silane moieties and tetramethyl titanate dispersed in a normally solid alkylene-alkyl acrylate copolymer matrix. These compositions are useful as extrudates about wires and cables, water-curing in a relatively short period of time to crosslinked products.
