⭐ What Is PTMEG 2000?

PTMEG 2000 (Polytetramethylene Ether Glycol 2000) is a reactive polyether polyol used in the production of polyurethane (PU) elastomers, spandex fibers, adhesives, and coating systems.
With a molecular weight of approximately 2000 g/mol, it produces polyurethane materials that are more flexible, softer, and highly impact-resistant.

PTMEG is a high-purity polyether diol derived from the polymerization of THF (Tetrahydrofuran).

🔧 What Is PTMEG 2000 Used For?

PTMEG 2000 reacts with isocyanates such as MDI or TDI to form high-performance polyurethane chains.

Its main contributions include:

✔ 1. Provides High Elasticity

PTMEG 2000 delivers excellent flexibility and superior rebound properties in PU elastomers.

✔ 2. Improves Abrasion & Impact Resistance

Ideal for applications requiring durability under mechanical stress.

✔ 3. Enhances Hydrolysis Resistance

It performs better than ester-based polyols in humid or wet environments.

✔ 4. Maintains Flexibility at Low Temperatures

Remains elastic and stable across a wide temperature range.

✔ 5. Adds Flexibility to PU Adhesives

Helps create strong yet flexible bonding in polyurethane adhesive systems.

🎯 Purposes of PTMEG 2000

✔ 1. Polyurethane Elastomer Production

Commonly used in:

• Industrial PU wheels
• Rollers
• Sealing gaskets
• Shock absorbers & bumpers
• Molded elastomer parts
