The 1.03 specific gravity of mPPE is 25% to 40% lower than other insulation materials such as PVC, polyethylene, and cross-linked polyethylene. Along with the reduced wall thickness, the low specific gravity yields significant weight savings of around 25%. Wires and cable with mPPE insulation meet UL 1581 requirements for operation at 80°C and 105°C, as well as UL VW-1 UL flame resistance. The mPPE material also offers a 10x better abrasion and pinch resistance than PVC. Although it is not as thick, it is tougher. The better tensile strength and lower hardness ratings combine to provide a tough, durable, and flexible insulation. Finally, EcoWire® is recyclable. Plastics present significant disposal issues. Its harmful additives leak into the groundwater in landfills and produce toxic gases when burned. PVC can be recycled but it is not always technically feasible and rarely cost effective. Other common wire insulations present similar, if less severe, problems. On the other hand, mPPE is thermoplastic and more easily recycled as it does not contain the aforementioned hazardous materials.
