1. General structure

Chemical structure

Fluorocarbon elastomers are synthesized from a limited number of organic monomers, mainly highly fluorinated entities:

• propylene hexafluoride – HFP ;

• vinylidene fluoride – VF ₂ ;

• tetrafluoroethylene – TFE;

• perfluoromethylvinyl ether – PMVE.

But also :

• suppliers of vulcanization sites for crosslinking by organic peroxide/coagent systems;

• propylene to facilitate processing.

The two main categories of elastomers marketed are as follows.
