Physical Properties of PTMEG

The physical properties of PTMEG (polytetrahydrofuran ether glycol) include:
Molecular weight and morphology: The molecular weight of PTMEG is usually between 600 and 5000. PTMEG with a lower molecular weight is a colorless liquid at room temperature, while PTMEG with a higher molecular weight is a white wax. The molecular weight of PTMEG that can be used in elastic materials and elastic fibers is usually between 1000 and 2000.
Thermal stability: PTMEG has good thermal stability, allowing it to be processed and used at high temperatures while not easily decomposing and deteriorating.
