Polybutadiene Hydroxyl-Terminated (HTPB) waa nooc ka mid ah caag dareere ah oo leh miisaan unugyo kala duwan (qiyaastii 1500-10,000 g/mol) iyo heer sare oo waxqabad falcelis ah.Caag dareere ah ayaa leh hanti isku-dhafan oo gaar ah oo ay ku jiraan heerkulka kala-guurka galaas hooseeya, dabacsanaanta heerkulka hooseeya, awoodda culeyska adag ee sare, iyo awoodda socodka oo aad u fiican.Waxaa si weyn loogu isticmaalay xabagta, dahaarka, shaabadda, daawada, iyo sidoo kale agabka tamarta leh.

HTPB waa dareere dhalanteed leh oo midab la mid ah warqadda dhuka iyo viskosity la mid ah sharoobada galleyda.Guryuhu way kala duwan yihiin sababtoo ah HTPB waa isku dhafka halkii ay ka ahaan lahayd xarun saafi ah, waxaana loo soo saaray si loo buuxiyo shuruudaha gaarka ah ee macaamiisha.
