PTFE Material Properties

Polytetrafluoroethylene (PTFE), commonly known as “Plastic King,” is a polymer obtained by polymerizing tetrafluoroethylene as a monomer. It possesses the following main properties:

1. High and Low Temperature Resistance: It can be used long-term at temperatures ranging from -180°C to 260°C, with minimal changes affected by temperature variations. Some sources also indicate a usable temperature range of -190°C to 260°C.

2. Teflon hose Chemical Resistance: It exhibits excellent chemical stability, being almost insoluble in all solvents and resistant to corrosion by almost any chemical reagent, except for molten alkali metals. For example, boiling in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even aqua regia results in no change in weight or properties.

3. Teflon hose Electrical Insulation: It is unaffected by the environment and frequency, with a volume resistivity of up to 10^18 ohm-cm, low dielectric loss, and high breakdown voltage.

4. Teflon hose Non-stick Surface: It has the lowest known surface energy of solid materials, with no known solid material able to adhere to its surface.

5. PTFE Self-lubricating: It has the smallest friction coefficient among plastics, making it an ideal oil-free lubricating material.

6. Atmospheric Aging Resistance: Long-term exposure to the atmosphere leaves its surface and properties unchanged.

7. Radiation Resistance: It has low permeability.

8. Non-flammability: Its limiting oxygen index is below 90
