  • Tetrahydrofuran THF

Tetrahydrofuran THF

Tetrahydrofuran (THF), with the chemical formula C₄H₈O, is an important cyclic ether solvent. It appears as a colorless transparent liquid with an ether-like odor. It features low viscosity, high volatility, and excellent solvency power, being completely miscible with water and most organic solvents in any proportion. THF exhibits extremely strong dissolving capacity for various plastics, resins, and polymers, serving as the primary solvent for polyvinyl chloride (PVC). It is widely used in chemical, pharmaceutical, coating, and other industries.
