## Abstract

Described is an insulated non-halogenated, heavy metal free vehicular cable comprising an inner core of a copper based metal wire having a cross sectional area of at least about 0.1 mm2, and an outer insulation, covering the length of the inner core, comprised of a thermoplastic polyphenylene ether composition that has no halogen or heavy metal added thereto, the insulated cable capable of meeting the testing standard ISO 6722.

## Claims

### Claim 1

An insulated non-halogenated, heavy metal free vehicular cable comprising:
an inner core of a copper based metal wire having a cross sectional area of about 0.1 mm2 to 0.13 mm2,
an outer insulation, covering the length of the inner core, comprised of a thermoplastic polyphenylene ether composition that has no halogen or heavy metal added thereto, wherein the polyphenylene ether comprises a polymer formed from an ethylenically unsaturated material, the insulation having improved abrasion resistance, and
wherein the insulated cable is constructed and arranged to withstand flame at a 45 degree angle such that any combustion flame of the outer insulation extinguishes within 70 seconds and a minimum of 50 mm of insulation at the top of the insulated cable remains unburned, and to have a scrape abrasion resistance of greater than 100 cycles using a 7N load and a 0.45 millimeter needle.

### Claim 2 (depends on 1)

The insulated cable of claim 1 in the form of an automotive wire harness.

### Claim 3 (depends on 1)

The insulated cable of claim 1 wherein the inner core of the copper based metal wire has a cross sectional area of 0.13 mm2.

### Claim 4 (depends on 1)

The insulated cable of claim 1 wherein the ethylenically unsaturated material comprises an olefinically unsaturated material.

### Claim 5 (depends on 1)

The insulated cable of claim 1 wherein the ethylenically unsaturated material comprises a styrene butadiene material.
