PTMEG 1000 – Polytetramethylene Ether Glycol

Description

What is PTMEG 1000 – Polytetramethylene Ether Glycol?

PTMEG 1000 – Polytetramethylene Ether Glycol, molecular weight ~1000 is a high-performance polyether glycol known for its superior flexibility, elasticity, and durability. It is a white, waxy solid or viscous liquid (depending on temperature) with excellent reactivity, making it a preferred raw material in the production of spandex fibers, thermoplastic polyurethanes (TPU), elastomers, coatings, and adhesives.

Its unique molecular structure ensures outstanding hydrolysis resistance, low-temperature flexibility, and exceptional mechanical strength, making PTMEG an essential building block for advanced polymer formulations.

Key Applications of PTMEG 1000 – Polytetramethylene Ether Glycol

PTMEG 1000 – Polytetramethylene Ether Glycol is widely used as a soft segment in elastomeric segmented polymers. Its unique two-phase morphology (rigid hard segment and flexible soft segment) provides outstanding elasticity, resilience, and long-term durability. Compared to polyesterdiols, PTMEG offers superior hydrolytic stability, low-temperature flexibility, and resistance to extractables, making it ideal for high-performance applications.
