Iimveliso
I-Hydroxyl Terminated Polybutadiene
I-Hydroxyl-terinated polybutadiene (HTPB) luhlobo lwerubha elulwelo olunobunzima obuhlukeneyo bemolekyuli (malunga ne-1500-10,000 g / mol) kunye nomgangatho ophezulu wokusebenza okusebenzayo.Irabha elulwelo inendibaniselwano ekhethekileyo yeepropathi ezibandakanya iqondo lobushushu elisezantsi leglasi, ukuguquguquka kobushushu obuphantsi, umthamo ophezulu wokulayisha okuqinileyo, kunye nokukwazi ukuhamba okugqwesileyo.Ziye zasetyenziswa ngokubanzi kwi-adhesives, i-coatings, i-sealants, amayeza, kunye nezixhobo ezinamandla.
I-HTPB lulwelo oluguquguqukayo olunombala ofana nephepha le-wax kunye ne-viscosity efana nesiraphu yombona.Iipropati ziyahluka ngenxa yokuba i-HTPB ngumxube kunekhompawundi esulungekileyo, kwaye yenziwe ukuhlangabezana neemfuno ezithile zabathengi.
