Physical description & handling notes

Tetrafluoroethylene, stabilized appears as a colorless odorless gas. Easily ignited. Vapors are heavier than air. May asphyxiate by the displacement of air. May violently polymerize under prolonged exposure to fire or heat, violently rupturing the container. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Water insoluble.

Documented Uses

Used to produce polytetrafluoroethylene polymers (Teflon); [ACGIH]
In prepn of propellants for food product aerosols
MONOMER FOR POLYTETRAFLUOETHYLENE RESINS; CHEM INT FOR HEXAFLUOROPROPYLENE; COMONOMER FOR PERFLUOROALKOXY RESINS, FLUORINATED ETHYLENE-PROPYLENE RESINS, & ETHYLENE-TETRAFLUOROETHYLENE RESINS; TERMONOMER WITH VINYLIDENE FLUORIDE & HEXAFLUOROPROPYLENE
Used as a copolymer with hexafluoropropylene to substitute for polytetrafluoroethylene
It is used mainly for the production of fluoropolymers. It reacts with perfluoronitrosoalkanes to produce so-called nitroso rubbers. It is also used in the production of low molecular mass compounds and intermediates, for example, for the manufacture of iodoperfluoroalkanes.
Principal industrial use of CF2:CF2 is for preparation of polytetrafluoroethylene (Teflon (R)) Resins and copolymers.
