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.
Product 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%.
Product 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.
