MG wire is a high-temperature wire suitable for use in applications up to 450 degrees Celsius. The wire features heat-resistant insulation and a fiberglass braid outer jacket. If exposed to fire, the wire has minimal smoke generation. The high temp mica tape insulation does not melt or soften except at very high temperatures. You can use MG wire for high-temperature industrial applications like smelters, ovens, and kilns. It has good chemical resistance.
