Polytetramethylene Ether Glycol Instruction:

Polytetramethylene ether glycol (PTMEG) is a homopolymer obtained by cationic ring-opening polymerization. PTMEG is a linear polyether glycol with primary hydroxyl groups. At room temperature, PTMEG is a white waxy solid. When the temperature exceeds room temperature, PTMEG is melted into a clear, colorless liquid. PTMEG is readily soluble in alcohols, esters, ketones, aromatic and chlorinated hydrocarbons and insoluble in aliphatic hydrocarbons and water.

PTMEG Description:

PTMEG is mainly used in the production of polyurethane elastomers, polyurethane elastomers (Spandex) and ester-ether copolymer elastomers. the largest consumer market for PTMEG is spandex with about 49%, followed by polyurethane elastomers with about 35% and ester-ether copolymer elastomers with about 15%. PTMEG is a very PTMEG is a very important raw material of polyether polyol for the production of polyurethane elastomer products. In China, PTMEG is mainly used in spandex and polyurethane elastomers. PTMGE is essentially a gap in ester-ether copolymer elastomers.

Polytetrahydrofuran (PTMEG) is a raw material for the production of spandex and polyurethane elastomers. With the global development of polyurethane and polyurethane elastomers, the market demand for polytetrahydrofuran (PTMEG) is also increasing. The United States consumed 83,000 and 88,000 tons of PTMGE in 2002 and 2003, respectively. 98,000 tons were consumed in 2005, which means an annual growth rate of 6.6% from 2002 to 2005. In Western Europe, the market supply in 2003 was 67,000 tons, with a total value of about 235 million U.S. dollars. 60% was used for spandex and 19% for polyurethane elastomers. in 2003, the market demand for polytetrahydrofuran (PTMEG) in Japan was 27,000 tons, of which 2/3 was used for the production of urethanes, 17% for polyurethane elastomers, 8% for polyether elastomers and the rest for polyurethane coatings, polyurethane adhesives and others.

PTMEG is a homopolymer obtained by cationic ring-opening polymerization of the monomer tetrahydrofuran (THF) in the presence of a catalyst.PTMEG is a linear polyether glycol with primary hydroxyl groups. At room temperature, PTMEG is a white waxy solid.
