ʻO ka Hydroxyl-terminated polybutadiene (HTPB) he ʻano o ka ʻili wai me ke kaumaha molekala like ʻole (ma kahi o 1500-10,000 g/mol) a me kahi kiʻekiʻe o ka hana reactive.Loaʻa i ka ʻōpala wai kahi hui kūʻokoʻa o nā waiwai e like me ke aniani hoʻololi haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe ka hoʻouka paʻa, a me ka hiki ke kahe maikaʻi.Ua hoʻohana nui ʻia lākou i nā adhesives, coatings, sealants, lāʻau lapaʻau, a me nā mea ikaika.

He wai translucent ka HTPB me ke kala e like me ka pepa wax a me ka viscosity like me ka syrup kulina.ʻOkoʻa nā waiwai no ka mea he hui ʻia ʻo HTPB ma mua o kahi hui maʻemaʻe, a ua hana ʻia ia e hoʻokō i nā koi kikoʻī o nā mea kūʻai aku.
