Tohu Hua

Ko te Hydroxyl-terminated polybutadiene (HTPB) he ahua o te rapa wai he rereke te taumaha ngota (tata ki te 1500–10,000 g/mol) me te taumata teitei o te mahi tauhohenga.Ko te rapa wai he huinga ahurei o nga taonga tae atu ki te iti o te pāmahana whakawhiti karaihe, te ngawari o te pāmahana, te kaha ki te uta totoka, me te kaha rere pai.Kua whakamahia nuitia i roto i te whakapiri, te paninga, te hiri, te rongoa, tae atu ki nga taonga hihiko.

Ko te HTPB he wai whakawhiti he rite te tae ki te pepa ware pi me te pokey rite ki te tirikara witi.He rereke nga taonga na te mea he ranunga te HTPB ehara i te puhui parakore, ka hangaia kia tutuki nga whakaritenga motuhake a nga kaihoko.
