How is PTMEG Used

Polytetramethylene ether glycol (PTMEG) is a waxy white solid that melts to a colorless, clear, viscous liquid near room temperature.

PTMEG is produced by the catalytic polymerization of tetrahydrofuran (THF). The main applications of PTMEG are the production of spandex (polyurethane) fibers, polyurethane elastomers, and copolyester-ether elastomers.

Poly Butylene Adipate-Co-Terephthalate

图片
Poly Butylene Adipate-Co-Terephthalate is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. PBAT has the characteristics of both PBA and PBT, with good ductility and elongation at break, as well as good heat resistance and impact performance; in addition, PBAT also has excellent biodegradability, and is one of the most popular and best degradable materials in biodegradable plastic research and market application.

BDO

图片
1.4-Butanediol ( BDO ) is used industrially as a solvent and in the manufacture of certain types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1.4-butanediol is used in the synthesis of gamma-butyrolactone (GBL). In the presence of phosphoric acid and high temperatures, 1.4-Butanediol dehydrates into the important solvent tetrahydrofuran. At about 200°C, in the presence of a soluble ruthenium catalyst, the diol undergoes a dehydrogenation reaction to form butyrolactone. BDO is used to synthesize 1,4-butanediol diglycidyl ether, which is then used as an epoxy resin diluent.
