Poly(tetrahydrofuran)丨CAS 25190-06-1

Poly(tetrahydrofuran), often referred to as polytetrahydrofuran or PTMEG, is primarily used as a key raw material in the production of thermoplastic polyurethanes (TPUs), elastomers, and coatings. It serves as a flexible polyol in polyurethane chemistry, contributing to soft segments that provide elasticity, toughness, and abrasion resistance in TPU products. PTMEG is also employed in the manufacture of adhesives, sealants, and coatings where flexibility and chemical resistance are essential. In industrial applications, it is used for fibers, spandex, and specialty elastomeric materials, as well as in research for developing high-performance polymers, copolymers, and novel materials with tunable mechanical and thermal properties.

Poly(tetrahydrofuran) offers several advantages that enhance its utility in polymer and material applications. Its linear, flexible structure imparts excellent elasticity, low-temperature flexibility, and high tensile strength to polyurethane and elastomeric products. PTMEG exhibits chemical resistance, hydrolytic stability, and compatibility with various diisocyanates, enabling robust and durable formulations. Its controllable molecular weight allows precise tuning of mechanical, thermal, and rheological properties in end-use materials. Additionally, PTMEG supports consistent processing, reproducibility, and long-term performance in coatings, elastomers, and fiber applications.
