>> POLYTETRAMETHYLENE ETHER GLYCOL (PTMEG)
◎ Process : Korea PTG Co., Ltd.
◎ Korea PTG Co., Ltd. has newly developed the manufacturing process of
    polytetramethylene ether glycol(PTMEG). This process utilizes the continuous
    production system of the most excellent quality with high consistency. PTMEG is
    synthesized by the polymerization of Tetrahydrofuran(THF). It is colorless and
    viscous liquid over room temperature. PTMEG is mainly used for production of
    polyurethane, elastomers, spandex fibers and copolyester-ether elastomers.
      Korea PTG has a variety of product specification with seven standard grades of
    molecular weights in 210, 650, 1000, 1400, 1800, 2000 and 3000. PTMEG products
    with other molecular weights can be produced upon special request of customers.
