PTMEG 1800 Used in the Production of Polyurethane Elastomer, Foam, Spandex Fiber
1. Description
PTMEG 1800 (Polytetramethylene EtherGlycol) is a diol with a nominal molecular weight of 1800, produced through the polymerization of tetrahydrofuran (THF). Its enhanced reactivity makes it well-suited for use in polyurethane applications.
Manufacturing Process:
Monomer: THF Polymer: PTMG
C4H8O + H2O → H(OCH2CH2CH2CH2)nOH
2. Application
PTMEG 1800 is widely used in the production of conventional polyurethane elastomers, including spandex fibers, artificial leather coatings, thermoplastic polyurethane (TPU), thermoplastic polyester elastomers, and various other applications such as adhesives and foams.

5. Storage
PTMEG 1800 is hygroscopic and absorption of moisture would affect polyurethane reactivity and physical properties of resulting polymer. The material should be stored in sealed containers and in dry conditions, away from direct sources of light. The recommended storage temperature is between 40 ~ 45 ℃. Opened drums must be reclosed tightly immediately after drawing off material.
6. Package
200kg / drum; ISO Tank Container
7. Handling Precautions
PTMEG 1800 has a very low odor and acute toxicity, posing no significant health hazard to users. However, standard industrial hygiene practices should be followed when handling this chemical. Appropriate protective clothing and safety glasses should be worn to prevent unnecessary contact or accidental ingestion. In case of skin or eye contact, rinse immediately with plenty of clean water. If eye contact occurs, seek medical attention promptly.
8. Fire and Explosion
PTMEG polyether glycol is combustible under certain conditions and may explode if heated to its decomposition temperature in a confined space. Fires involving polyols can be extinguished using water fog, carbon dioxide, or dry chemical extinguishers.
