Wire Insulation Identification/Application Guide

Insulation Code	Insulation Type		Appearance	Insulation Temperature Range*	Abrasion Resistance	Flexibility	Water Submersion
	Overall	Conductors
KK	Kapton	Kapton		-267 to 316°C (-450 to 600°F)	Excellent	Good	Good
TG	Glass Braid	PFA Teflon or Neoflon		-73 to 260°C (-100 to 500°F)	Good	Good	Excellent
GG (Extension Grade-EXGG)	Glass Braid	Glass Braid		-73 to 482°C (-100 to 900°F)	Poor	Good	Poor

Insulation Code	Resistance To:					Comments
	Solvent	Acid	Base	Flame	Humidity
KK	Good	Good	Good	Good	Excellent	Fused Kapton Tape Approx. 0.15 mm Applied to Conductors. A 0.10 mm Jacket is Then Applied to Both. 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 Approx. 260°C (500°F)]
TG	Excellent	Excellent	Excellent	Excellent	Excellent	PFA Extruded Over Each Bare Wire 0.12 mm Silicon Impregnated Glass is Overbraided Over Both. May Be Used for Single Measurement to 343°C (650°F).
GG (Extension Grade-EXGG)	Excellent	Excellent	Excellent	Excellent	Fair	0.12 mm Glass Yarn Braided Over Each Conductor, Impregnated with Silicon Varnish, Then Covered Together with 0.12 mm Glass Braid. Varnish Improves Moisture and Abrasion Resistance, but is Destroyed Above 204°C (400°F).
