fluoropolymers
A fluoropolymer is a fluorocarbon-based polymer with multiple carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and Base (chemistry), bases. The best known fluoropolymer is polytetrafluoroethylene under the bra ...

solvents
A solvent (from the Latin '' solvō'', "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for p ...

Synthesis
Perfluorocyclohexane can be synthesized by fluorination of cyclohexane.
Properties
Perfluorocyclohexane is chemically inert and thermally stable. It is a relatively non-toxic, clear, waxy solid, which has a high
vapor pressure
Vapor pressure or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indicat ...
