Used as a key component in the production of high-performance polyurethane elastomers, coatings, adhesives, and sealants. Its long, flexible ether backbone provides excellent low-temperature flexibility, hydrolytic stability, and resistance to oxidation. Commonly employed in automotive parts, industrial wheels, rollers, and hydraulic seals due to its durability and resilience. Also utilized in spandex fibers for textiles, where it contributes to stretch and recovery properties. Preferred in applications requiring long-term mechanical performance and resistance to environmental degradation.
