PCTFE ROD, PCTFE sheet and PCTFE Hollow bar
Polychlorotrifluoroethylene (PCTFE) 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 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.
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 glass transition temperature (Tg) is around 45 °C.
PCTFE has one of the highest limiting oxygen index (LOI) It has good chemical resistance. It also exhibits properties like zero moisture absorption and non wetting.
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, ethers, esters and aromatic compounds.PCTFE is resistant to oxidation because it does not have any hydrogen atoms.
Main PCTFE products we offer: PCTFE Rod, PCTFE Sheet, PCTFE tube and PCTFE seal& PCTFE seat as per drawing.
