PTMEG 3000 – Polytetramethylene Ether Glycol

Description

What is PTMEG 3000 – Polytetramethylene Ether Glycol?

PTMEG 3000 (Polytetramethylene Ether Glycol) is a high-performance polyether glycol derived from tetrahydrofuran (THF). It is a linear diol with a molecular weight of around 3000, designed specifically for applications that require superior flexibility, elasticity, and hydrolytic stability.

PTMEG 3000 is widely used as a soft segment in polyurethane (PU) and polyester formulations, making it essential in industries such as spandex fibers, thermoplastic polyurethane (TPU), elastomers, coatings, and adhesives. Its excellent mechanical strength and resistance to hydrolysis make it one of the most reliable raw materials for high-performance polymers.

Technical Specifications of PTMEG 3000

• Molecular Weight Range: 2877–3206

• OH Value: 35–39 mg KOH/g

• Color (APHA): ≤ 50

• Acid Value: ≤ 0.05 mg KOH/g

• Water Content: ≤ 0.02%

Key Applications of PTMEG 3000 – Polytetramethylene Ether Glycol

PTMEG 3000 – Polytetramethylene Ether Glycol is widely used as a soft segment in elastomeric segmented polymers. Its unique two-phase morphology (rigid hard segment and flexible soft segment) provides outstanding elasticity, resilience, and long-term durability. Compared to polyesterdiols, PTMEG offers superior hydrolytic stability, low-temperature flexibility, and resistance to extractables, making it ideal for high-performance applications.

• Primary raw material for spandex production.

• Provides excellent stretch recovery, elasticity, and comfort.

• Extensively used in swimwear, hosiery, underwear, bandages, and diapers.

2. Thermoplastic Polyurethanes (TPU / TTPU)

• Enhances flexibility, abrasion resistance, and impact strength.

• Exhibits excellent resistance to hydrolysis and microbial attack.

• Maintains elasticity even at very low temperatures.

• Used in footwear, films, dashboards, radiator grills, ski boots, hoses, pipes, catheters, and industrial parts.

3. Thermoplastic Polyether Esters (TPEE)

• Excellent mechanical properties across a wide temperature range.

• Provides strong resistance to oils, fats, and most solvents.
