A peroxide-crosslinkable composition comprising:

Peroxide-crosslinkable compositions and processes for their manufacture

The process for making extra high voltage cable insulation is improved by using a composition comprising in weight percent based on the weight of the composition: (A) 95 to 99.9% of an ethylene-based polymer; (B) 0.2 to 2.5% peroxide; (C) 0.01 to 0.5% of a sulfur-containing first antioxidant having at least one &#x2014;S(CH)COR group, wherein R is C6 to C20 alkyl; (D) 0.001 to 0.009%) of a sulfur-containing second antioxidant that does not contain a &#x2014;S(CH)COR group, wherein R is a C6 to C20 alkyl; (E) Optionally, an organic nitrogenous base; and (F) Optionally, a phenolic third antioxidant that does not contain a &#x2014;S(CH)COR group, wherein R is a C6 to C20 alkyl.

Cable insulation compositions comprising a sulfur-containing second antioxidant

A peroxide-crosslinkable composition comprising: The composition is useful in the manufacture of insulation sheaths for high and extra high voltage wire and cable.

The process for making extra high voltage cable insulation is improved by using a composition comprising in weight percent based on the weight of the composition: (A) 95 to 99.9% of an ethylene-based polymer; (B) 0.2 to 2.5% peroxide; (C) 0.01 NI to 0.5% of a sulfur-containing first antioxidant having at least one &#x2014;S(CH)2COR group, wherein R is a C6 to C20 alkyl; (D) 0.001 to 0.009%) of a phosphorus-containing second antioxidant that does not contain a &#x2014;S(CH)C0R group, wherein R is a C6 to C20 alkyl; (E) Optionally, an organic nitrogenous base; and (F) Optionally, a phenolic third antioxidant that does not contain a &#x2014;S(CH)C0R group, wherein R is a C6 to C20 alkyl.

Cable insulation compositions comprising a phosphorus-containing antioxidant

Highly-mineral-filled, halogen-free, flame-retardant compositions made from or containing a polypropylene thermoplastic elastomer, a polypropylene, a metal hydroxide filler, and a polar-monomer-grafted polyolefin elastomer compatibilizer. Such compositions can be employed in preparing various articles of manufacture, including extruded articles and coated conductors, such as cables.
