California Fine Wire Co. offers a high-quality PTFE (polytetrafluoroethylene) insulation that is ideal for demanding applications requiring low friction, non-stick properties, and exceptional chemical resistance.

Our proprietary coating process applies a thin, uniform layer of PTFE directly to the wire without the need for primers. This ensures a high-purity insulation with excellent adhesion and minimal added bulk, allowing us to maintain tight dimensional tolerances even on fine and ultra-fine wire sizes. 

We can apply PTFE insulation to any alloy that we carry, offering a broad range of insulation thicknesses that can be tailored to your specific requirements. Our PTFE-coated wire is compatible with most insulated wire connectors, supporting a variety of assembly and termination methods. 

Whether you’re working in aerospace, medical, or high-tech electronics, California Fine Wire Co.’s PTFE-insulated wire offers the durability, precision, and flexibility for your applications’ demands.

More Information

Connector Compatibility

PTFE insulation allows for soldered, crimped, or thermally joined terminations without cracking or peeling. It is compatible with a range of insulated wire connectors and supports high-density layouts without compromising reliability. The insulation’s strength and flexibility are especially valuable in miniaturized electronic packages and tight routing environments.

Specific Industry Applications

PTFE insulated wire performs reliably in systems exposed to vibration, temperature changes, and corrosive conditions. Aerospace programs use it for signal and power connections in avionics and control systems. Defense contractors rely on it for rugged assemblies that must hold up under mission-specific stress. In electronics, PTFE insulation supports signal clarity in sensors, circuit boards, and test equipment. Research groups use this wire in prototypes, instrumentation, and measurement devices.

PTFE coated wire also works well with insulated wire connectors, allowing for consistent connections that resist breakdown or degradation. Its non-stick surface and thermal stability make it easy to handle during assembly and suitable for compact connector designs.

Quality and Compliance

California Fine Wire Co. holds ISO 9001 certification and complies with DFARS, REACH, RoHS, and ITAR regulations. All wires are manufactured with consistency and traceability in mind, from small prototypes to large production runs.
