Abstract: Unitary multiple conductor electrical cables, such as electrical power cords, are disclosed. Multiple conductor electrical cables are insulated with one or more layers of a thermoplastic polymer composition. The outer layer of the thermoplastic polymer composition contains an anti-microbial agent that resists biological contamination.

Abstract: Multiple conductor electrical power cords, signal transmitting wiring and cable is insulated with one or more layers or sheathing of a thermoplastic polymer composition with at least the outer layer of the composition containing contaminant resistant or combating agents that inhibit growth of biological contamination. The microbial resistant cord or wiring has particularly advantageous utility of power cords for use with appliances or electrical products in facilities that affect health, such as medical and food related facilities that require safeguarding against contaminating microorganism attack formation, or growth.
