USE
Tetrahydrofuran (THF), the saturated derivative of furan, when used as a solvent for high molecular weight polyvinyl chloride (PVC), vinyl chloride copolymers, and polyvinylidene chloride copolymers at ambient temperatures yields solutions of high solids content. Blends of THF and methyl ethyl ketone are often used for increased solvency in certain polymer compositions. Applications for THF polymer solutions include PVC top coatings of automotive upholstery, audio tape coatings of polyurethane/metal oxides on polyester tape, polyurethane coatings for fabric finishes, water-vapor barrier film coatings of PVC, and polyvinylidene chloride copolymers onto cellophane film. Tetrahydrofuran is an excellent solvent for many inks used for printing on PVC film and on PVC plastic articles. Polyvinyl chloride pipe welding cements are made by dissolving the resin in THF solvent. Other adhesive applications include cements for leather, plastic sheeting, and for molded plastic assemblies. Other uses of THF are as a chemical intermediate and as a complexing solvent for various inorganic, organometallic, and organic compounds. These THF complexes are important as Grignard reagents, catalysts for organic reactions, and in stereo-specific polymerizations. Tetrahydrofuran is the solvent of choice in many pharmaceutical reactions and applications. The excellent solvency of THF makes this solvent ideal for solvent cleaning of polymer manufacturing and processing equipment.
