MG Mica Glass wire is engineered for extremely high-temperature environments where standard insulation fails. It uses a single nickel-plated copper conductor wrapped with mica tape and a braided fiberglass jacket to handle thermal stress up to 450°C. Ideal for internal wiring in ovens, kilns, furnaces, and power plants, this wire delivers reliable performance under continuous heat, vibration, and demanding industrial conditions.
It uses a mica tape layer that stays stable up to 450°C, plus a fiberglass braid for extra heat and abrasion protection. It handles hotter environments than TGGT, SRML, or SF-2 wire.
It’s used inside industrial ovens, kiln controls, furnace wiring, power-plant equipment, and other spots where standard 200-250°C wire will fail.
Yes, but only moderately. The mica + fiberglass layers add stiffness compared to silicone or PTFE-based wires. It’s meant for fixed installs, not constant movement.
The mica layer is flame-resistant and does not propagate fire, but you should still follow proper insulation and spacing rules for live conductors.
Most MG wires use nickel-plated copper in standard strand counts. For extra-flex builds, Pro Wire & Cable can special-order alternate constructions.
