PTMEG/Spandex (2024 Program)

Polytetramethylene ether glycol (PTMEG) is a key ingredient in the production of a variety of elastomeric urethane products and is a major component of spandex fibers. Minor applications are as the soft block in co-polyester and co-polyamide elastomers, and in a number of very small miscellaneous applications. PTMEG has few uses, even in small volumes, in applications where it is not a monomeric input to a polymeric species. Cost of production estimates for PTMEG and Spandex are included for the United States and China.
