Polytetramethylene Ether Glycol (PTMEG) Usage and applications

Polytetrahydrofuran (PolyTHF) is an important raw material for the production of polyurethanes (such as polyurethane fibers, polyurethane elastomers, synthetic leather, coating additives, adhesives and sealants), polyesters and polyamides.
Detailed usage:
-Polyurethane fibers (spandex): swimwear, underwear, sportswear, stockings, etc.
-Polyurethane elastomers (thermoplastic elastomers, thermosetting elastomers): automotive parts, cables and wires, hoses and pipes, wheels and rollers, solid tires, etc.
-Synthetic leather: shoes, bags, etc.
-Paints, coating agents: waterproof coatings, etc.
-Adhesives, sealants: adhesives for industrial and construction purposes.
Polytetramethylene ether glycol, polytetrahydrofuran, polytetramethylene ether glycol (PTMEG) have good properties as soft segments of polyurethane and polyester resins. The resulting resins are widely used, from ordinary consumer products such as clothing to industrial materials such as machine parts.
Applications are expected to continue to grow now and in the future.

Handling and storage:
PTMEG is hygroscopic and degrades if exposed to oxygen or air. That is why it should be sealed with dry nitrogen.
PTMEG is a white wax at room temperature, but becomes a clear, colorless liquid when heated. If PTMEG solidifies in a drum, you can keep the drum at about 70 degrees for about a day to allow it to melt. But avoid local heating. For liquid storage, it is recommended to keep the temperature of PTMEG below 50 degrees.
PTMEG 650 and 850 are classified as hazardous materials in the Japanese Fire Protection Law, Class 4, Petroleum Type No. 4, Hazard Class III. PTMEG has low volatility and is unlikely to catch fire at room temperature. But if it catches fire, use dry powder, alcohol-resistant foam or large amounts of water to extinguish the fire. Although polytetramethylene ether glycol, polytetrahydrofuran, polytetramethylene ether glycol (PTMEG) has relatively low toxicity and is relatively safe, use standard protective equipment such as goggles and gloves when handling.
