PTFE Insulated High Temperature Wire
Product Overview
PTFE insulated high temperature wire is designed for industrial applications requiring reliable electrical performance under extreme temperatures up to 260°C. With excellent chemical resistance, low dielectric loss, and long-term thermal stability, this wire is widely used in industrial heating equipment, instrumentation systems, aerospace applications, and high-temperature control environments where conventional cables cannot operate reliably.
CableApex supplies PTFE high temperature wire engineered for continuous operation in demanding conditions. Conductor structure, voltage rating, and insulation thickness can be customized to meet specific project and application requirements.
