PTMEG

PTMEG is a polymer of tetrahydrofuran and obtained from tetrahydrofuran by way of catiolic ring opening polymerization in the presence of catalyst. Its name is Polytetramethylene Ether Glycol and for short, PTMEG. Its other names in common use are furfuryl polyether, polytetramethylene ether glycol. PTMEG is hydroxyl-terminated polyether diol and is white wax-like solid at ambient temperature and becomes transparent liquid after melting with no certain melting point and freezing point but with certain hygroscopicity and oxidability. It is flammable at high temperature, somewhat toxic under normal temperature but irritating to skin and eyes
