Alaabta
Hydroxyl ayaa la joojiyay Polybutadiene
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.

Xusuusin
1) Dhammaan xogta farsamada ee kor lagu tilmaamay waa tixraacaaga.
2) Faahfaahin dheeraad ah ayaa lagu soo dhaweynayaa dood dheeraad ah.
4. Isticmaalka: HTPB waxaa si weyn loo isticmaalaa in dhammaan nooc ka mid ah motor leh kimikal adag oo kiimiko ah ee duulista iyo hawada hawada, xabagta qoriga, sidoo kale isticmaalka madaniga ah, waxaa loo isticmaali karaa in beeraha oo ay ku jiraan alaabta PU, tuuraya alaabta elastomer, rinji, korontada Qalabka dahaaran ee dahaaran iwm.
5. Miisaanka saafiga ah 170kg 200 litir ee durbaanka birta ah ee polyetylen.
