Application

Polytetramethylene Ether Glycol serves as a versatile component in various industrial applications due to its unique chemical properties. With a melting point ranging from 11 to 38 °C and a viscosity of 100 to 4,400 mPa.s at 40 °C, this material is particularly effective in the synthesis of soft segment polyurethanes, enhancing the flexibility and durability of the final product. Additionally, it is utilized to modify the surface of cellulose fibers, which can then be employed as reinforcing materials in polymer matrix composites. Although it is only slightly soluble in water and insoluble in ether, its macromolecular structure of repeating oxybutylene units makes it an essential ingredient in developing advanced materials.
