UL 1332 FEP Insulated Teflon Wire for High-End Lighting and Sensing Systems
Compact, Durable, and Heat-Resistant Wiring Solutions for Extreme Environments
CableApex’s UL 1332 FEP wire is the premier choice for lighting engineers and industrial designers who demand performance in compact spaces. Featuring advanced FEP (Fluorinated Ethylene Propylene) insulation, this wire provides a 200°C (392°F) temperature rating with a significantly thinner wall than silicone or PVC. Utilizing 99.99% high-purity oxygen-free tinned copper (OFC), it ensures exceptional signal integrity and resistance to oxidation. Its non-stick surface and immunity to almost all industrial chemicals make it indispensable for HID/LED lighting, high-temperature sensors, and laboratory instruments.
