PTMEG 2000 – Polytetramethylene Ether Glycol

Description

What is PTMEG 2000 – Polytetramethylene Ether Glycol ?

PTMEG 2000 – Polytetramethylene Ether Glycol, molecular weight ~2000 is a high-performance polyether glycol widely used as a soft segment in the production of advanced polymers. It appears as a white, waxy solid or viscous liquid (depending on temperature) with excellent reactivity and superior mechanical properties.

Known for its outstanding elasticity, hydrolysis resistance, and low-temperature flexibility, PTMEG 2000 – Polytetramethylene Ether Glycol is a key raw material in the manufacture of thermoplastic polyurethanes (TPU), spandex fibers, polyurethanes, elastomers, and specialty coatings. Its higher molecular weight compared to PTMEG 1000 provides enhanced flexibility, tensile strength, and improved resilience in end-use applications.

Key Applications of PTMEG 2000 – Polytetramethylene Ether Glycol

PTMEG 2000 – 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.
