Polytetrafluoroethene (PTFE) is a widely used polymer material that has various properties making it suitable for many applications. The following statements describe some of the characteristics of PTFE:

Thermoplastic Material:
- PTFE is a thermoplastic material, which means it can be molded into different shapes when heated and then cooled down. This property allows for easy manufacturing and processing of PTFE.

High Friction Coefficient:
- This statement is incorrect. PTFE has a low friction coefficient, which means it has a slippery surface that reduces friction with other materials. This property makes it suitable for use in bearings, seals, and other applications where smooth movement is required.

Electric Insulator:
- PTFE is an excellent electric insulator, which means it can resist the flow of electric current. This property makes it useful in electrical applications, such as wire insulation, circuit boards, and other electronic components.

Non-sticking to surfaces:
- PTFE is non-sticking to surfaces, which means it can resist adhesion from other materials. This property makes it useful in applications where sticking or adhesion can be a problem, such as non-stick coatings for cookware and industrial equipment.

Thermosetting Material:
- This statement is incorrect. PTFE is not a thermosetting material, which means it does not harden when heated. Instead, it remains flexible and pliable.

In summary, the correct statements about PTFE are that it is a thermoplastic material, has a low friction coefficient, and is an excellent electric insulator. Additionally, it is non-sticking to surfaces, which makes it useful in many applications.
