3. Fluorinated elastomers

The main commercial fluoroelastomers resulting from copolymerization are briefly described below:

vinylidene fluoride with perfluoropropene (or hexafluoropropene) 3.1 ;
tetrafluoroethylene with a perfluorinated vinyl ether 3.2 ;

Statistical and economic data

Worldwide consumption of fluoropolymers remains relatively low compared with that of other plastics and elastomers. However, these modest tonnages correspond to significant sales figures, due to the high price of fluoropolymers.

Sales prices in 2002 were approximately as follows for pellets (and about double that for semi-finished products):

Standards

The American Society for Testing and Materials (ASTM) has published a number of standards concerning both fluoropolymers themselves and certain semi-finished products made from them. The main standards are listed below. This standardization remains a reference, as Afnor or Iso standardizations are few in number; nevertheless, there are a few mentioned here too.
