Characteristics of Polytetrafluoroethylene

1. High-temperature resistance: Operating temperature up to 250°C.

2. Low-temperature resistance: Possesses good mechanical toughness; even when the temperature drops to -196°C, it can maintain an elongation rate of 5%.

3. Corrosion resistance: It exhibits inertness toward most chemicals and solvents, and can withstand strong acids, strong bases, water, and various organic solvents.

4 Weather resistance: Has the **aging life** among plastics.

5 High Lubricity: It has the lowest coefficient of friction among solid materials.

6 Non-adhesion: It refers to the smallest surface tension in solid materials, meaning it does not adhere to any substance.

7. Non-toxic and harmless: It possesses physiological inertness and, when used as artificial blood vessels or organs for long-term implantation in the body, causes no adverse reactions.
