Karabo e rarahane. PTFE's molecular structure gives it outstanding insulation across most of its operating range, but exceeding 260°C triggers irreversible degradation. And while cold temperatures improve electrical properties, they make the coating brittle.

Key takeaway: Despite enhanced electrical insulation at low temperatures, the PTFE coating becomes brittle. For cryogenic applications (eg, liquid nitrogen lines, superconducting magnets), ensure the cloth is not subjected to sharp bending or mechanical stress below -79°C.
