Patent ID: 6861143

Claim:
A cable, comprising: at least one conductor; and at least one covering layer; wherein the at least one covering layer comprises a thermoplastic polymer material, wherein the thermoplastic polymer material comprises: a propylene homopolymer; or a copolymer of propylene with an olefin comonomer; wherein the olefin comonomer is ethylene, one or more α-olefins other than propylene, or ethylene and one or more α-olefins other than propylene, wherein the propylene homopolymer or copolymer of propylene has: a melting point between 140° C. and 165° C.; a melting enthalpy between 30 J/g and 80 J/g; a boiling diethyl ether soluble fraction less than or equal to 12 wt %, wherein the boiling diethyl ether soluble fraction has a melting enthalpy less than or equal to 4 J/g; a boiling n-heptane soluble fraction between 15 wt % and 60 wt %, wherein the boiling n-heptane soluble fraction has a melting enthalpy between 10 J/g and 40 J/g; and a boiling n-heptane insoluble fraction between 40 wt % and 85 wt %, wherein the boiling n-heptane insoluble fraction has a melting enthalpy greater than or equal to 45 J/g.
