Description
Polytetrahydrofuranum est solidum cerum album, facile solubile in alcoholibus, esteribus, ketonibus, hydrocarbonibus aromaticis et hydrocarbonibus chlorinatis, sed insolubile in hydrocarbonibus aliphaticis et aqua. In liquidum pellucidum mutatur cum temperatura temperaturam ambientem excedit.
Applicatio
Polytetrahydrofuranum praecipue ut segmentum molle polyurethani segmentati vel polyetheri polyesteris segmentati adhibetur. Gummi polyurethanum segmentatum ex polytetrahydrofurano factum, pondere moleculari medio 1000 habens, ad pneumatica, cingula transmissionis, obturacula, et cetera adhiberi potest; etiam ad tunicas , corium artificiale, pelliculas, et cetera adhiberi potest. Polyester polyetheri segmentatus productus elastomer thermoplasticus est. Polytetrahydrofuranum, pondere moleculari medio 2000 habens, ad fibras elasticas polyurethanas faciendas adhiberi potest.
