What is the difference between perfluoroelastomer and fluoroelastomer materials?
Fluoroelastomer refers to a synthetic polymeric elastomer in which carbon atoms in the main chain or side chains contain fluorine atoms. The introduction of fluorine atoms endows rubber with excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance, and resistance to atmospheric aging. Perfluoroelastomers are monomer terpolymerizations in which all hydrogen atoms are replaced by fluorine atoms; the absence of hydrogen atoms in the molecular chain results in a significantly enhanced heat resistance. These rubbers possess the elasticity and sealing properties of synthetic rubber, along with the chemical inertness and thermal stability of PTFE materials. It is an upgraded version of fluororubber; the upgraded version of this product is perfluoroether rubber
