Until now, only cables insulated with silicone or thermoplastic insulators like PFA benefited from a manufacturing process that didn't oxidize the copper. But starting today, the new process offers a more economical alternative to cables with PFA insulation over polished copper. In fact, PTFE is less expensive than PFA while offering the same thermal characteristics.
The other advantage of this process is that it eliminates the need to coat the copper with silver or nickel to protect the conductor from oxidation.
In addition to being an exceptional electrical insulator, PTFE has high chemical resistance, withstands welding temperatures (350°C), and is self-extinguishing.
It also withstands abrasion very well. Unlike thermoplastic materials such as PFA, PTFE does not melt and allows for thinner insulation than silicone-insulated cables. PTFE-insulated cables are the ideal solution for applications subjected to temperatures exceeding 200°C, such as those found in household appliances (ovens, cooktops, boiler burners, etc.) and automotive applications (engine areas).
