Description

Tetrahydrofuran (THF) is a highly versatile, polar aprotic solvent widely used in polymer production and specialty chemical synthesis. It is known for its excellent solvency power, low viscosity, and compatibility with water and a variety of organic compounds. THF is primarily utilized as a precursor for the manufacture of PTMEG, essential in producing elastomers and spandex fibers. With its strong dissolving properties and ability to stabilize reactive intermediates, THF plays a vital role in pharmaceuticals, adhesives, coatings, and chemical processing.
