EcoWire hook-up wire uses a modified polyphenylene ether (mPPE) thermoplastic that is inherently lighter, tougher, and more flame-resistant than PVC. The result is UL AWM wires that are smaller than their PVC-based counterparts. The non-halogenated insulation contains no heavy metal pigments, allowing it to help manufacturers meet Waste Electrical and Electronic Equipment (WEEE) requirements. For example, a 20 AWG PVC-insulated wire has a diameter of 0.101 in. (2.57 mm). The equivalent EcoWire has a diameter nearly 50% smaller at 0.055 in. (1.40 mm).
The initial EcoWire offering is a UL AWM 11028 wire available in sizes from 28 AWG (0.07 mm²) to 10 AWG (5.37 mm²) with solid or stranded tinned copper conductors. Rated for operating temperatures to 105°C, the wires meet UL VW-1 flammability requirements.
