Mica & Fiberglass High Temperature Wire

Mica & Fiberglass High Temperature Wire (Up to 450°C) AWM Wiring for Ovens & Heating Equipment

Mica and fiberglass high temperature wire refers to AWM constructions designed for extreme heat environments where conventional PVC, XLPE, or standard silicone wire may fail. These wires typically use mica tape insulation combined with fiberglass braid protection to deliver strong heat resistance and stable dielectric performance in high-temperature zones.

This category covers high temperature AWM options commonly specified for ovens, furnaces, heating equipment, and industrial thermal systems, where wiring must withstand sustained exposure to elevated temperatures. Because mica/fiberglass structures are intended for extreme heat applications, proper installation and mechanical protection are recommended to avoid damage during routing and service.

CableApex supplies multiple mica and fiberglass AWM styles to match different voltage ratings and temperature requirements. If your project requires flexibility rather than maximum heat resistance, UL3135 silicone wire may be a better choice. For fluoroplastic insulation and chemical resistance at high temperature, UL10362 PFA and UL1332 FEP wire are also available within our AWM wire range.
