Do you know why few renowned politicians earned 'Teflon' tag before their name? It's because Teflon is a highly non-sticky and non-reactive compound.
Most historic use of Teflon is its application in the Manhattan project. For more information regarding Teflon mesh, you can visit http://www.elkofiltering.com/store/c/30-Teflon-Mesh.aspx
Chemical nature of Teflon
As we know, it's just a name to a group of fluoropolymer resins like,
1. Polytetrafluoroethylene (PTFE)
2. Fluorinated ethylene propylene (FEP)
3. Perfluoroalkoxy (PFA)
However, PTFE is the original resin that was trademarked. Later, other resins were developed for specific uses.
What makes Teflon tubing special?
1. It is least corrosive when compared to other materials used in making tubes. That makes Teflon the best candidate for tubing applications where there are corrosion and contamination risk. Nuclear reactors, cooking utensils, medical machinery are few of the most common uses.
2. Fluoropolymer resins can withstand extreme weather conditions. Many of those polymers have workable temperatures from -67°C to 500°C and suffer no mechanical change throughout the range. So, you can confidently use Teflon tubing in case of extreme temperature variation.
3. Teflon compounds are almost chemically inert. Besides, its lubricious characteristic and very low friction coefficient make Teflon the best tubing material for a difficult and highly frictional environment.
4. These resins also have very high tensile strength. So, you can be sure regarding almost no mechanical change against heavy stress. Just, for example, the tensile strength of PTFE is between 2500 to 4000 PSI and that of FEP is 3500 PSI.
