Polytetrahydrofuran Description:

Polytetrahydrofuran, also known as polytetramethylene ether glycol or polytetramethylene oxide, is a chemical compound with the chemical formula (H(OCH2CH2CH2CH2)nOH). PTMEG can be regarded as a polymer of tetrahydrofuran or as a polyether derived from 1,4-butanediol.

The product is marketed as a low average molecular weight polymer with an average molecular weight between 250 and 3000 Daltons. In this form, PTMEG is a white waxy solid that melts between 20 and 30°C. This commercial product can be further processed into polymers with molecular weights of 40,000 or higher.

PTMEG Instruction:

Polytetramethylene ether glycol (PTMEG) is the premier polyether polyol used worldwide for the manufacture of high performance polyurethane elastomers. known for its many performance properties and processing advantages, PTMEG is used in a variety of applications across multiple industries. These applications include polyurethane resins, prepolymers, coatings, adhesives, foundry polyurethane resins, spandex fibers, and more.

PTMEG Applications:

Polytetrahydrofuran is mainly used for the synthesis of elastic fibers, such as spandex and polyurethane. In the latter process, polyurethane is first dissolved in a solvent as one of the prepolymers. When used in the manufacture of artificial leather, polytetrahydrofuran is used as a raw material together with isocyanates or reacted with other derivatives of isocyanic acid to obtain polyurethane.
