☑ Tetrahydrofuran yog siv los ua ib qho hnyav forresins, vinyls, thiab siab polymers.
☑ Tetrahydrofuran yog siv feem ntau (80%) los ua polytetramethylene ether glycol, lub hauv paus polymer siv feem ntau hauv kev tsim cov elastomeric fibers (xws li, spandex) nrog rau polyurethane thiab polyester elastomers (xws li, tawv tawv, skateboard log).Cov seem (20%) yog siv rau hauv cov ntaub ntawv hnyav (xws li, yeeb nkab cements, adhesives, luam ntawv inks, thiab sib nqus daim kab xev) thiab ua cov tshuaj hnyav hauv tshuaj thiab tshuaj syntheses.
☑ Cov ntawv thov rau THF polymer cov kev daws teeb meem suav nrog PVC txheej txheej sab saum toj ntawm lub tsheb upholstery, suab daim kab xev txheej ntawm polyurethane / hlau oxides ntawm polyester daim kab xev, polyurethane coatings rau ntaub tiav, dej-vapor barrier zaj duab xis txheej ntawm PVC, thiab polyvinylidene chloride copolymer rau cellophane zaj duab xis.
☑ THF complexes yog ib qho tseem ceeb raws li Grignard reagents, catalysts rau organic tshua, thiab nyob rau hauv stereo-specific polymerizations.
