Hauj lwm
PolyTetrahydrofuran yog ib qho khoom dawb uas zoo li roj nplaum uas yooj yim yaj hauv cov cawv, esters, ketones, aromatic hydrocarbons thiab chlorinated hydrocarbons, tab sis insoluble hauv aliphatic hydrocarbons thiab dej. Nws hloov mus ua kua pob tshab thaum qhov kub tshaj qhov kub hauv chav.
Daim ntawv thov
Polytetrahydrofuran feem ntau yog siv los ua ntu mos ntawm segmented polyurethane lossis segmented polyether polyester. Cov segmented polyurethane roj hmab ua los ntawm polytetrahydrofuran nrog qhov nruab nrab molecular hnyav ntawm 1000 tuaj yeem siv los ua cov log tsheb, cov hlua txuas, gaskets, thiab lwm yam. nws kuj siv tau rau tsho tiv no, tawv tawv, zaj duab xis, thiab lwm yam. Cov segmented polyether polyester uas ua tau yog ib tug thermoplastic elastomer. Polytetrahydrofuran nrog qhov nruab nrab molecular hnyav ntawm 2000 tuaj yeem siv los ua polyurethane elastic fibers.
