Polytetrafluoreethylene(PTFE) Applications And Properties
As you see it has very complex name and you could not hold in your mind probably. But it is very prominent thermoplastic polymer material in most of our lives. This material is also called as ‘teflon’ which we are more hearsay about it. In here, we give some of information about polytetrafluorethylene and its applications and properties.
What Is PTFE?
If we take a look at the molecular structure of teflon, we can see replacement of H atoms with F atoms at polymer chains. And these long and not cross-linked molecular structure makes teflon thermoplastic polymer. General properties of PTFE;
- Teflon is very resistant to temperature which makes teflon is commonly used material in most cooking pans.
- Teflon is very resistant to chemical or environmental attack, and unaffected by water applications. This property makes teflon is proper material for chemical and food applications.
- Teflon has very low coefficient of friction which makes teflon is very appropriate polymer product for nonlubricating bearings that are used in machinery.
What Are The Properties Of PTFE?
The production method of teflon is addition polymerization. Unlike the most amorphous thermoplastics, teflon has 95% of crystalline structure in it. Modulus of elasticity of teflon is around 450 MPa. Tensile strength of teflon is around 20 MPa. Actually teflon is an elastic polymer which has elongation ratio of 100-300% according to its original shape. Glass transition temperature of teflon is around 127C and melting temperature of teflon is around 327C.
These are the main properties and applications of polytetraflourethylene. Do not forget to leave your comments and questions about teflon polymer below. Your precious feedbacks are very important for us.
