Product Description
Tetrahydrofuran (THF) is a versatile solvent with numerous industrial applications. Several sizes fit any application, from 1/2 pints up to three gallons. Comes with a pouring nozzle for transferring product and easy refilling. All sizes ship in a rigid metal container and are fully DOT-compliant.
THF is a clear, colorless, low-viscosity liquid with an ether-like odor. THF exhibits high volatility and an extremely low freezing point. At 20°C, THF is completely miscible with water (H2O). Due to its tendency to form peroxides during storage, it is inhibited with BHT.
Applications:
Polycarbonate (Lexine) - THF can chemically bond polycarbonate parts with a minimal set time. The applicator needle is ideal for applying small amounts of this water-thin material.
3-D Printing - THF can smooth PLA prints and blend layer lines. Laboratory Use-THF is used in large quantities in research institutions worldwide as a solvent for numerous chromatographic techniques, such as Gel Phase Chromatography. Its broad solvency capabilities are consistently reliable.
Adhesives - THF solvents can be used to join rigid plastic pipes and in compounded cement for leather, plastic sheet film extrusions, and molded plastic parts assemblies.
PVC Cement - THF-PVC formulations meet NSF standards. THF solvent cement can be formulated with additional solvents and inorganic fillers to control set time. THF can also serve as a PVC-type cleaner prior to joint formation.
Reaction Solvent - THF is very stable under extremely basic conditions and is therefore the choice for numerous specialized syntheses involving complex catalysts and Grignard reagents.
Misc. Solvent Applications: Natural Products, Industrial Resins, Elastomers, Polyurethane Coatings, Printing Inks.
