Daim ntawv thov
Poly (tetrahydrofuran), feem ntau hu ua polytetrahydrofuran lossis PTMEG, feem ntau yog siv los ua cov khoom siv tseem ceeb hauv kev tsim cov thermoplastic polyurethanes (TPUs), elastomers, thiab coatings. Nws ua hauj lwm raws li ib tug saj zawg zog polyol nyob rau hauv polyurethane chemistry, pab rau cov mos ntu uas muab elasticity, toughness, thiab puas kuj nyob rau hauv cov khoom TPU. PTMEG tseem ua haujlwm hauv kev tsim cov nplaum nplaum, sealants, thiab coatings qhov yooj yim thiab tshuaj tiv thaiv yog qhov tseem ceeb. Hauv cov ntawv thov kev lag luam, nws yog siv rau cov fibers, spandex, thiab cov ntaub ntawv tshwj xeeb elastomeric, nrog rau kev tshawb fawb los tsim cov khoom siv siab tshaj -polymers, copolymer, thiab cov ntaub ntawv tshiab nrog cov khoom tunable thiab thermal zog.
Cov txiaj ntsig
Poly (tetrahydrofuran) muaj ntau yam zoo uas txhim kho nws cov khoom siv hauv cov khoom siv polymer thiab cov ntaub ntawv siv. Nws cov kab, hloov tau yooj yim imparts zoo elasticity, qis -kub yooj, thiab siab tensile zog rau polyurethane thiab elastomeric khoom. PTMEG nthuav tawm cov tshuaj tiv thaiv, hydrolytic stability, thiab compatibility nrog ntau yam diisocyanates, ua kom muaj zog thiab ruaj khov formulations. Nws qhov hnyav molecular tswj tau tso cai rau kev kho kom haum ntawm cov tshuab, thermal, thiab rheological zog thaum kawg - siv cov ntaub ntawv. Tsis tas li ntawd, PTMEG txhawb kev ua haujlwm zoo ib yam, rov tsim dua tshiab, thiab ua haujlwm ntev -lub sijhawm ua haujlwm hauv cov txheej txheej, elastomers, thiab cov ntawv siv fiber ntau.
Xaus
Poly (tetrahydrofuran) yog ntau yam polyol siv hauv polyurethane elastomers, coatings, adhesives, thiab tshwj xeeb polymer daim ntaub ntawv. Nws yooj yim, tshuaj stability, thiab tunable zog ua rau nws yog ib qho tseem ceeb tivthaiv rau siab - cov ntaub ntawv ua tau zoo. Zuag qhia tag nrho, Poly (tetrahydrofuran) txhawb kev txhim kho elasticity, durability, thiab kev ua haujlwm thoob plaws ntau hom kev lag luam thiab kev tshawb fawb.
