What does PCTFE stand for?
PCTFE (Polychlorotrifluoroethylene) is a homopolymer of Chlorotrifluoroethylene. The replacement of a single fluorine atom on the carbon backbone with a chlorine atom, changes the properties of the fluoropolymer to allow melt processing.
What is Pctfe plastic?
PCTFE (polychlorotrifluoroethylene), commonly referred to as Kel-F® or Neoflon®, is a fluoropolymer material with outstanding strength, stiffness, and dimensional stability. PCTFE has excellent chemical resistance, radiation resistance, and flammability characteristics.
What monomer is Pctfe made of?
chlorotrifluoroethylene
polychlorotrifluoroethylene (PCTFE), synthetic resin formed by the polymerization of chlorotrifluoroethylene.
How is Polychlorotrifluoroethylene made?
polychlorotrifluoroethylene (PCTFE), synthetic resin formed by the polymerization of chlorotrifluoroethylene. PCTFE powder can be melted and then shaped by molding or by extrusion into solid articles. …
What does peek stand for?
Polyether ether ketone
Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures.

How is Pctfe made?
polychlorotrifluoroethylene (PCTFE), synthetic resin formed by the polymerization of chlorotrifluoroethylene. It is a moldable, temperature-resistant, and chemical-resistant plastic that finds specialty applications in the chemical, electrical, and aerospace industries.
Who discovered Polychlorotrifluoroethylene?
Polychlorotrifluoroethylene- Chemical compound (PCTFE) PCTFE was discovered in 1934 by Fritz Schloffer and Otto Scherer who worked at IG Farben.
Which is the chemical formula for chlorotrifluoroethylene?
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.
How is chlorotrifluoroethylene used in cryogenic applications?
Chlorotrifluoroethylene. Chlorotrifluoroethylene ( CTFE) is a chlorofluorocarbon with chemical formula CF2CClF. 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.
Which is a homopolymer of polychlorotrifluoroethylene or CTFE?
Polychlorotrifluoroethylene. It is similar to polytetrafluoroethene (PTFE), except that it is a homopolymer of the monomer chlorotrifluoroethylene (CTFE) instead of tetrafluoroethene. It has the lowest water vapor transmission rate of any plastic.
What is the trade name for chlorotrifluoroethylene Neoflon?
CTFE has a carbon-carbon double bond and so can be polymerized to form polychlorotrifluoroethylene or copolymerized to produce the plastic ECTFE. PCTFE has the trade name Neoflon PCTFE from Daikin Industries in Japan, and used to be produced under the trade name Kel-F from 3M Corporation in Minnesota.
