Chlorotrifluoroethylene (CTFE) is a chlorofluorocarbon with chemical formula CFCl=CF 2. It is commonly used as a refrigerant in cryogenic applications. CTFE has a carbon-carbon double bond and so can be polymerized to form polychlorotrifluoroethylene or copolymerized to produce the plastic ECTFE .
PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE), whereas PTFE is a homopolymer of tetrafluoroethylene. The monomers of the former differs from that of latter structurally by having a chlorine atom replacing one of the fluorine atoms.
ECTFE (ethylene-chlorotrifluoroethylene) is an alternating copolymer of ethylene and chlorotrifluoroethylene. It is a semi-crystalline fluoropolymer (a partly fluorinated polymer ), with chemical corrosion resistance properties.
CClF 2 CCl 2 F → C 2 F 3 Cl 2 + Cl• Cl• + O 3 → ClO• + O 2. This reaction is followed by: ClO• + O → Cl• + O 2. The process regenerates Cl• to destroy more O 3. The Cl• will destroy an average of 100,000 O 3 molecules during its atmospheric lifetime of 1–2 years. [12]
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
It was determined that this material was a new-to-the-world polymer. Tests showed the substance was resistant to corrosion from most acids, bases and solvents and had better high temperature stability than any other plastic. By early 1941, a crash program was making substantial quantities of PTFE for the Manhattan Project. [1] [2] [3] [4]
Chlorine trifluoride is an interhalogen compound with the formula ClF 3.It is a colorless, poisonous, corrosive, and extremely reactive gas that condenses to a pale-greenish yellow liquid, the form in which it is most often sold (pressurized at room temperature).
