Polytetramethylene Ether Glycol
(PTMEG)
 Â
Introduction
    Shanxi Sanwei Group Co., Ltd. has
established a set of *5,**0tons/year Polytetramethylene Ether
Glycol (PTMEG) plant using international advanced technology and
equipment in China. State Council approves this PTMEG project
despite the contribution to national debt as it helps to close the
technological gap for this process in China and enables Sanwei
spearhead the product chain based on 1,*-Butanediol that will have
a creative impact and significance to the development of
chemical industry in China.

Properties
    PTMEG is a white waxy solid. It turns into
transparent liquid when the temperature is higher than room
temperature. It dissolves easily in alcohols, esters, ketones,
aromatic hydrocarbons and hydrocarbon chlorides. However, it does
not dissolve in water or fatty hydrocarbons. When its molecular
weight increases, its solubility drops. At room temperature, PTMEG
is a good absorbent of water despending on its molecular weight and
maximum up to 2%.Â

Uses
    PTMEG is an important raw material for the
production of polyurethane (such as PU fibers, polyurethane
elastomer, synthesized leathers, paint additives, adhesives and
sealants), polyesters and polyamides.

  Storage and
Transportation
    PTMEG should be stored in
totally closed containers sealed with dry nitrogen. The containers
must be fitted with heating equipment outside or inside to keep
their internal temperature at about *0℃. Frozen PTMEG can be
heated at about *0℃ for *4 hours to melt. PTMEG should not be
stored at *0℃ for a long time.
     In addition, it should be stored in
cool, dry and well-ventilated places, and keep away from fire
sources, sparks and naked flames. Due to PTMEG water absorbent and
ease of oxidization, it should not be exposed to moisture or air.
To avoid static electricity, its containers should be earthen
during transportation.
     PTMEG becomes highly combustible at
high temperature. If fire is started, one could use spray water,
alcohol foam, dry chemicals products or carbon dioxide fire
extinguishers to put off the fire. When loading or unloading it,
one should wear gloves and safety glasses to prevent contacting
with the eyes or skin.
