CAS #504-63-2
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 3000 is notable for improving resiliency, rebound, and abrasion resistance in formulations.
