Publication number: 20100209705Abstract: Compositions useful as coatings for automobile power cables comprise a combination of raoisiure-crosslinkabk, si lane-grafted ethylene polymers in combination with a non-halogenated flame retardant. The ethylene polymers are a combination of at least one ethylene polymer with a density of 0.910 g/cc or greater and at least one ethylene polymer with a density less than 0.910 g/cc. The non-halogenated flame retardant is typically liydrated metallic filler, e.g., aluminum trihydrate. These compositions meet SAE J-1128 and DaimlerChrysler MS-8288 specifications, exhibit good shelf-life stability, and are useful in other automotive cable applications, such as ISO-6722.Type: ApplicationFiled: September 9, 2008Publication date: August 19, 2010Inventors: Thomas S.
