Melting point of pctfe
This results in having a relatively lower melting point among fluoropolymers, [19] around 210–215 °C. [2] PCTFE is resistant to the attack by most chemicals and oxidizing agents, a property exhibited due to the presence of high fluorine content. However, it swells slightly in halocarbon compounds, … Meer weergeven Polychlorotrifluoroethylene (PCTFE or PTFCE) is a thermoplastic chlorofluoropolymer with the molecular formula (CF2CClF)n, where n is the number of monomer units in the polymer molecule. It is similar to Meer weergeven It was discovered in 1934 by Fritz Schloffer and Otto Scherer who worked at IG Farben Company, Germany. Meer weergeven PCTFE is an addition homopolymer. It is prepared by the free-radical polymerization of chlorotrifluoroethylene (CTFE) and can be carried out by solution, bulk, suspension and emulsion polymerization. Meer weergeven PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE), whereas PTFE is a homopolymer of PCTFE is Meer weergeven After World War II, PCTFE was commercialized under the trade name of Kel-F 81 by M. W. Kellogg Company in early 1950s. The name "Kel-F" was derived from … Meer weergeven PCTFE has high tensile strength and good thermal characteristics. It is nonflammable and the heat resistance is up to 175 °C. It has a low coefficient of thermal expansion. The Meer weergeven PCTFE finds majority of its application due to two main properties: water repulsion and chemical stability.
