Polytetramethylene Ether Glycol (PTMEG) is a high-performance polyether compound with the chemical formula (C4H8O)n. It is a colorless, odorless, and highly viscous liquid or solid, depending on its molecular weight, and is widely used as a key building block in the production of polyurethane elastomers, spandex fibers, and other advanced polymer materials. PTMEG 0650 is known for its lower viscosity, easier handling at room temperature, flexibility and resistance to wear and tear.
