Product Description:
Polytetramethylene Ether Glycol is widely used in the production of high-performance elastomers, particularly spandex fibers, which are essential in the textile industry for making stretchable fabrics like sportswear, swimwear, and undergarments. Its excellent flexibility, durability, and resistance to hydrolysis make it a key component in polyurethane elastomers, which are used in automotive parts, industrial hoses, and seals. Additionally, it serves as a lubricant base stock in synthetic lubricants, enhancing the performance and lifespan of machinery. In adhesives and coatings, it improves elasticity and adhesion properties, making it suitable for applications requiring strong, flexible bonds. Its compatibility with various chemicals and stability under different conditions further expands its use in specialized industrial applications.
