PS: za mu iya yin kowace sigar HTPB kamar yadda abokan ciniki suka buƙata, kuma za mu iya ƙirƙirar HTPB tare da sarkar hydroxyl -OH guda ɗaya, A halin yanzu, za mu iya yin hydrogenation na HTPB)
Shi da wakilin tsawaita sarka, wakilin haɗin gwiwa a cikin zafin jiki na ɗaki ko amsawar zafin jiki mai yawa na iya samar da tsarin hanyar sadarwa ta 3D na abun ciki mai warkarwa. Abun da ke warkarwa yana da kyawawan halaye na injiniya, musamman juriya ga hydrolysis, juriya ga acid da alkali, juriya ga lalacewa, juriya ga ƙarancin zafin jiki da kyakkyawan rufin lantarki.
Ana iya ƙera polyurethanes da aka shirya daga HTPB don takamaiman halaye na zahiri; polyurethanes na iya zama masu laushi ko tauri da tauri. Wasu samfura sun haɗa da: bangarorin hana kumfa mai tauri; ƙafafun elastomeric masu ɗorewa da tayoyi (ana amfani da su don masu ninkaya, masu hawa dutse, skateboards, da sauransu); bushings na dakatar da motoci; mahaɗan tukunya na lantarki; manne masu aiki mai yawa; murfin saman da manne na saman; zare na roba (misali, Spandex); ƙarƙashin kafet; sassan filastik masu tauri (misali, don kayan aikin lantarki).
