Polytetrahydrofuran (PTMEG)

Polytetrahydrofuran (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 primary uses of PTMEG are in the production of spandex (polyurethane) fibers, polyurethane elastomers, and copolyester-ether elastomers.

Difference Between Ethylene Glycol and Polyethylene Glycol

图片
Difference Between Ethylene Glycol and Polyethylene Glycol Difference Between Ethylene Glycol and Polyethylene Glycol: Ethylene glycol  and polyethylene glycol are two different compounds. Ethylene glycol is an organic compound with the chemical formula C2H6O2. It is a colorless, odorless, sweet-tasting liquid that is used as an antifreeze and coolant in automobiles and other machinery. It is also used in the manufacture of polyester fibers and resins. Polyethylene glycol is a synthetic polymer made up of repeating units of ethylene glycol. It is a viscous, colorless, odorless liquid that is used as a lubricant, surfactant, and emulsifier in a variety of products. It is also used in the manufacture of cosmetics, pharmaceuticals, and food additives. Ethylene glycol  is a colorless, odorless, sweet-tasting, viscous liquid that is a simple diol (two hydroxyl groups on adjacent carbon atoms). It is used as an antifreeze and coolant in automobiles and other applications. It is also...

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.
