ETFE (Tefzel) Wires
This ethylene tetrafluoroethylene (also known as Tefzel) insulated wire in manufactured to meet the requirements of defence standard 61-12 Part29/1. Its outer sheath resists temperatures up to +270 °C and has good chemical and abrasion resistance. The wire conductors are made from tin plated copper wire. The properties of ethylene tetrafluoroethylene wire make it suitable for use in a wide variety of industries and applications including, aerospace, nuclear cables, electronics wiring, medical wiring and appliance wiring.
