The 304 Type K 20 AWG Solid wire is an economical glass braid that can be used in a wide range of applications.  Each solid conductor is glass braided, color coded and impregnated with a resin that inhibits fraying and reduces friction.  A final layer of fiberglass is applied over the parallel conductors and a coat of resin is applied.  

This construction allows for a temperature rating of 900°F (482°C) continuously and spikes of 1000°F (538°C).  The impregnation resin will burn off a 400°F (204°C).  Available in ASTM E 230 type K Special limits of error 1.1°C or 0.4% (whichever is greater).

Suggested uses: Furnace survey work, Heat treating, Foundries, Glass and Ceramic plants, Extruders, Injection molding and Vacuum forming.
