O le HTPB o se polymer vai mamao, o le pa'u vai fou. E eseese ona meatotino ona o le HTPB o se paluga nai lo se mea mama, ma ua gaosia e fa'afetaui ai mana'oga fa'apitoa a tagata fa'atau. O se HTPB masani o le R-45M ma pito ta'itasi o le filifili e fa'ai'u i se vaega hydroxyl [OH]. PS: e mafai ona matou faia so'o se fa'aliliuga o le HTPB e pei ona talosagaina e tagata fa'atau, ma le mamanu fou o le HTPB i se filifili e tasi o le hydroxyl -OH, I le taimi nei, e mafai ona matou faia le hydrogenation o le HTPB.)
E mafai ona fa'atupuina e le sui fa'aopoopoga filifili, sui fa'afeso'ota'i i le vevela o le potu po'o le tali atu i le vevela maualuga le fausaga o feso'ota'iga 3D o mea e fa'amālōlōina. O mea e fa'amālōlōina e iai meatotino fa'ainisinia sili ona lelei, aemaise lava le tete'e lelei i le hydrolysis, tete'e i le acid ma le alkali, tete'e i le ofuina, tete'e i le vevela maualalo ma le fa'amafanafana eletise sili ona lelei.
E mafai ona fa'ainisinia polyurethanes ua saunia mai le HTPB mo ni meatotino fa'aletino fa'apitoa; e mafai ona matua'i fa'alelei pe faigata ma ma'a'a fo'i polyurethanes. O nisi oloa e aofia ai: paneli fa'amafanafana foam ma'a'a; uili ma pa'u elastomeric malolosi (e fa'aaogaina mo ta'avale fa'ase'e, fa'asitepu, skateboards, ma isi mea fa'apena); bushings fa'a'au'au ta'avale; mea fa'apipi'i eletise; mea fa'apipi'i maualuga le fa'atinoga; ufiufi luga ma mea fa'amaufa'ailoga luga; filo fa'apitoa (e pei o le Spandex); kapeta i lalo; vaega palasitika malo (e pei o mea faigaluega eletise).
O se fa'aoga taua o le HTPB o lo'o i totonu o le propellant solid roketi. E fusifusia ai le oxidizing agent, le suau'u ma isi mea fa'aoga i totonu o se mea malo ae e mafai ona fa'apipi'i i le tele o faiga fa'apipi'i. O le polyurethane fa'amālōlōina e galue o se suau'u i ia fa'afefiloi. Mo se fa'ata'ita'iga, o le propellant e pei o le "HTPB/AP/Al=12/68/20", o lona uiga, e fa'atatauina i le mamafa, HTPB fa'aopoopo i ai le curative 12% (binder and fuel), ammonium perchlorate 68% (oxidizer), ma le alumini powder 20% (fuel).
O mea fa'apena fo'i, e masani ona ta'ua o le APCP (ammonium perchlorate composite propellant) e fa'aaogaina i roketi tetele. O se APCP masani e gaosia le 2–3 taimi o le fa'amalosi fa'apitoa o le pauta uliuli o lo'o fa'aaogaina i le tele o afi roketi laiti.
E faʻaaogaina foʻi le HTPB o se suauʻu faʻafefiloi mo roketi.
O meatotino fa'atino o le HTPB e pei ona taua i lalo:
1. E le mafai ona 'aina le vai
2. Vaega hyroxyl tali atu
3. Vevela maualalo o le fesuia'iga o tioata
4. Lanu maualalo - vai mafiafia manino maualuga
5. Tete'e i le hydrolysis
6. Tete'e i le vevela maualalo
7. Maualalo le sosolo o le susu
8. Tete'e atu i vaila'au ma fa'avae vai
9. Tete'e malosi i le ofuina
10. Pipii lelei i le tele o mea fa'apipi'i
11. Meatotino e taofia ai le eletise
E mafai ona fa'aaogaina le HTPB i:
- Ufiufi
- Mea fa'apipi'i
- Mea fa'aola
- Polyurethane (PU)elastomers
- Mea Fa'apipi'i
- Mea fa'amaufa'ailoga
- Mea e fa'amafanafana ai le eletise
- Oloa pa'u
- Mea faufale i taavale ma vaalele
- Mea fau fale(e le susu, e tete'e i le 'ele, e fa'amafanafana i le vevela)
- Fa'aputuina ma fa'apipi'i
- Suiga o le Polymer
- ma le tele o isi isi ituaiga o faʻaaogaina.
afifiina:
Fa'aputuina i le 50kg/talipalau, 170kg/talipalau, O le vaitaimi e teu ai e 1 tausaga.
Fa'atonuga mo le saogalemu:
E tatau ona teuina i se nofoaga malūlū, mago ma lelei mo le ea. O le tulaga sili ona lelei o le -20 ~ 38℃. E 12 masina le umi e teu ai, afai e uma le aso, e mafai ona faʻaaogaina pe afai e tusa ai ma tulaga masani ma toe faia se suʻega. A o felauaiga e tatau ona ʻaloʻese mai le timu ma le susulu o le la. Aua neʻi faʻafefiloi ma se vailaʻau faʻaola malosi.
