A fluorinated thermoplastic with outstanding thermal, physical, and electrical properties. PTFE is generally restricted to applications requiring its special characteristics because its basic resin and processing costs are relatively high. PTFE wire products are highly recommended for miniature cable applications because of their superior thermal and electrical properties. PTFE is especially suitable for internal wiring-soldering applications where insulation melt back is a specific problem. PTFE insulation is outstanding in its resistance to oil, oxidation, heat, sunlight and flame; and also in its ability to remain flexible at low temperatures. It also has excellent resistance to ozone, water, alcohol, gasoline, acids, alkalis, aromatic hydrocarbons and solvents.
