PTMEG 3000 Used in the Production of Conventional Polyurethane Elastomer

1. Introduction

PTMEG 3000 is nominal 3000 molecular weight diol based on THF (Tetrahydrofuran) polymerization. It's enhanced reactivity make it well suited to use of polyurethane.

 

2. Manufacturing Process

Monomer: THF                    Polymer: PTMG

C4H8O + H2O → H(OCH2CH2CH2CH2)nOH

 

3. Application

PTMEG is widely used in the production of conventional polyurethane elastomers, including spandex fiber, artificial leather coatings, thermoplastic polyurethane (TPU), thermoplastic polyester elastomer, and various other products like adhesives and foams.

7. Storage 

PTMEG 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 fr om direct sources of light. The recommended storage temperature is between 20 ~ 95 ℃. Opened drums must be reclosed tightly immediately after drawing off material.

 

8. Handling Precautions

While PTMEG has a low odor and acute toxicity, standard industrial hygiene practices should be followed when handling it. Wear appropriate protective clothing and safety glasses to prevent unnecessary contact and accidental ingestion. In case of skin or eye contact, rinse thoroughly with water. If eye contact occurs, seek medical attention.

 

9. Fire and Explosion Hazard

PTMEG polyether glycol will burn under certain condition and can explode if heated to decomposition temperature in a confined area. Polyols fires can be extinguished with water fog, carbon dioxide or dry chemicals.
