PTMEG 2000 In Production Of Thermoplastic Polyurethane Spandex Fiber

PTMEG 2000 Used in Production of Thermoplastic Polyurethane Spandex fiber

1. Description

PTMEG 2000 (Polytetramethylene EtherGlycol) is a diol with a nominal molecular weight of 2000, derived from the polymerization of THF (Tetrahydrofuran). 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 2000 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.

4. Physical and Chemical Properties

5. Storage

PTMEG 2000 is hygroscopic, and moisture absorption can impact polyurethane reactivity as well as the physical properties of the resulting polymer. To maintain its quality, the material should be stored in sealed containers under dry conditions, away from direct light sources. The recommended storage temperature is between 40–45℃. Opened drums should be tightly resealed immediately after use to prevent moisture exposure.

6. Package

200kg / drum; ISO Tank Container

7. Handling Precautions

PTMEG 2000 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 and accidental ingestion. In the event of skin or eye contact, rinse immediately with plenty of clean water. If eye contact occurs, seek medical attention promptly.

PTMEG polyether glycol is combustible under certain conditions and may explode if heated to its decomposition temperature in a confined space. In case of fire, it can be extinguished using water fog, carbon dioxide, or dry chemical extinguishers.
