polütetrametüleeneeterglükool

Polytetramethylene ether glycol, often abbreviated as PTMEG, is a type of polyether polyol. It is a linear polymer produced by the ring-opening polymerization of tetrahydrofuran (THF). The resulting polymer has repeating ether linkages in its backbone, giving it flexibility and other desirable properties. PTMEG is a waxy solid at room temperature and is soluble in various organic solvents.

PTMEG is primarily used as a soft segment in the production of thermoplastic polyurethanes (TPUs) and other elastomers like polyester elastomers (TPEEs) and polyamide elastomers (TPEs). Its unique molecular structure contributes to the excellent properties of these materials, including good tensile strength, abrasion resistance, hydrolysis resistance, and low-temperature flexibility. These elastomers find applications in a wide range of industries, such as footwear, automotive parts, cables, hoses, and medical devices. The molecular weight of PTMEG can be controlled during the polymerization process, allowing manufacturers to tailor the properties of the final elastomer for specific applications. Its resistance to hydrolysis and microbial attack also makes it a preferred choice for applications exposed to moisture or biological environments.
