Hydroxyl kwụsịrị Polybutadiene
Hydroxyl-treminated polybutadiene (HTPB) bụ ụdị rọba mmiri mmiri nwere ịdị arọ molekụla dị iche iche (ihe dị ka 1500-10,000 g/mol) yana ọkwa dị elu nke arụ ọrụ mmeghachi omume.Igwe mmiri rọba nwere ngwakọta pụrụ iche nke gụnyere obere mgbanwe iko iko, mgbanwe ọnọdụ okpomọkụ dị ala, ikike ibu ihe siri ike, yana ikike ịgbapụta nke ọma.A na-eji ha eme ihe n'ọtụtụ ebe na nrapado, mkpuchi, mkpuchi, ọgwụ, yana ngwa ike.
HTPB bụ mmiri mmiri translucent nwere agba yiri akwụkwọ wax na viscosity yiri sirop ọka.Ngwongwo ndị ahụ dị iche iche n'ihi na HTPB bụ ngwakọta kama ịbụ ngwakọta dị ọcha, a na-arụpụta ya iji mezuo ihe ndị ahịa chọrọ.
