FEP wire is a specialized high-performance electrical wire insulated with Fluorinated Ethylene Propylene (FEP), a melt-processable fluoropolymer known for its excellent thermal, chemical, and electrical properties. It is widely used in industries where reliability under extreme conditions is critical, including medical, aerospace, industrial automation, and semiconductor environments.
This wire type is designed for continuous operation up to 200°C and exhibits exceptional resistance to chemicals, oils, solvents, and UV exposure. Its non-stick surface and low dielectric constant make it ideal for compact assemblies, signal transmission, and high-purity applications that demand insulation integrity and material cleanliness.
FEP wire constructions vary depending on application needs, commonly featuring stranded tinned copper or silver-plated copper conductors, and are available in a range of AWG sizes. Typical voltage ratings range from 300V to 600V, depending on the insulation thickness and compliance with UL standards such as UL1332 or UL10362.
Engineered to meet stringent safety and reliability requirements, FEP wire offers:
--Outstanding heat resistance (up to 200°C)
--Low flame propagation (UL VW-1 compliant)
--High dielectric strength and electrical stability
--Excellent flexibility and low friction for easy routing
--Resistance to moisture, chemicals, and environmental aging
Because of these properties, FEP wire is frequently selected by OEMs, cleanroom manufacturers, medical equipment developers, and aerospace system integrators for mission-critical wiring tasks.
Whether used in sterilization-ready equipment, high-frequency signal lines, or corrosive industrial environments, FEP wire delivers long-term performance and insulation reliability that meets both international safety regulations and performance expectations.
