PolyTetraFluoroEthylene (PTFE) – a special polymer

The material did have an exceptional resistance against practically all known chemicals.

PTFE displays a series of unique properties:
• Nearly universal chemical resistance (exceptions: elemental fluorine, CF3, molten alkali metals)
• Insoluble in all solvents below 300°C
• High service temperature stability up to 250°C
• Very low adhesiveness
• Very low friction coefficient
• Extremely hydrophobic
• Physiologically inert, contaminant free
• Very good electrical (high resistance) and dielectrical (very low dielectric number and loss factor) properties
• Nonflammable
• Highly weather resistant (UV resistant)
• Good mechanical properties: tough elastic, easily manufactured
