WebTraditionally, a fluoropolymer or fluoroplastic is defined as a polymer consisting of carbon (C) and fluorine (F). Sometimes they are referred to as perfluoropolymers to distinguish them from partially fluorinated polymers, fluoroelastomers, and other polymers that contain fluorine in their chemical structure. WebFluoropolymers is the class of polymer materials which contain fluorine atoms in their chemical structure. There are two types of fluoropolymers: Perfluoropolymers – In this polymer type, all the hydrogen atoms in the analogous hydrocarbon polymer structures were replaced by fluorine atoms
