Product Description:
Polytetramethylene ether glycol is widely used in the production of high-performance elastomers, particularly in the manufacturing of spandex fibers, which are essential in creating stretchable fabrics for clothing, sportswear, and medical garments. Its excellent elasticity and durability make it a key component in polyurethane elastomers, which are utilized in automotive parts, industrial hoses, and seals due to their resistance to abrasion, oil, and chemicals. Additionally, it is employed in the formulation of coatings and adhesives, providing flexibility, moisture resistance, and enhanced performance in harsh environments. Its applications also extend to the production of thermoplastic polyurethanes used in footwear, wire insulation, and flexible tubing, offering a balance of strength and elasticity.
