## **Kapton[®] Duplex Insulated Thermocouple Wire** 

Fused Kapton tape applied to conductors and jackets. Excellent moisture and abrasion resistance, high dielectric strength (7 kV/mil), retains much physical integrity after gamma radiation. FEP is used as adhesive binding agent [melts at approximately 260°C (500°F)]
