PTFE has been accidentally discovered  by  Roy Plunkett in 1938 in a TFE occult bomb; it has suddenly noted  for its high resistance to the most  aggressive chemical agents. Dupont has firstly produced it for the USA ARMY engaged in the equipment of the first atomic bomb.
 
Due to its remarkable characteristics,  PTFE is one of the most used materials in technical field; the most important features are:
- its complete insolubility  in water and in any other organic solvent;
- excellent dielectric properties;
- excellent fire resistance :it doesn’t spread the flame;
- excellent property of smoothness with a very low friction coefficient ;
- anti-adhesion : its surface cannot be sticked ; 
 
These are  some of the most important technical properties  of PTFE; they become more important if you consider that they don’t change in a temperature range between – 200 °c and +250°c.
 
To improve its excellent features, pls consider that we can add  special fillers which modify Its aspect, its mechanical, electric and physical  properties (elongation, tensile strength).
