Hydroxyl Terminated Polybutadiene
Hydroxyl-terminated polybutadiene (HTPB) yog ib daim ntawv ntawm cov roj hmab ua kua uas muaj qhov sib txawv molecular hnyav (kwv yees li 1500-10,000 g / mol) thiab qib siab ntawm reactive functionality.Cov roj hmab ua kua muaj qhov sib xyaw ua ke ntawm cov khoom xws li lub iav hloov pauv qhov kub thiab txias, tsis tshua muaj kev hloov pauv, muaj peev xwm thauj khoom siab, thiab muaj peev xwm txaus txaus.Lawv tau siv dav hauv cov nplaum nplaum, coatings, sealants, tshuaj, nrog rau cov khoom siv zog.
HTPB yog cov kua translucent nrog cov xim zoo ib yam li daim ntawv siv quav ciab thiab viscosity zoo ib yam li pob kws phoov.Cov khoom sib txawv vim HTPB yog ib qho sib tov es tsis yog cov khoom xyaw ntshiab, thiab nws yog tsim los ua kom tau raws li cov neeg siv khoom tshwj xeeb.
