Butyl rubber bụ polymer linear nwere isobutylene dị ka isi ahụ yana obere isoprene.N'elu agbụ nke butyl roba molecule, otu methylene ọ bụla ọzọ, e nwere otu methyl abụọ ahaziri n'ụdị okirikiri gburugburu agbụ isi, na-akpata nnukwu ihe mgbochi, na-eme ka usoro mkpụrụ ndụ butyl rọba kọmpat na agbụ molecular na-agbanwe dịtụ ogbenye. .Otú ọ dị, ọ na-emekwa ka butyl rọba magburu onwe ya n'ikuku ikuku, na-ebute ụzọ n'etiti rubbers niile.

Na mgbakwunye na njigide ikuku dị mma, butyl rubber vulcanizates nwekwara ezigbo nguzogide okpomọkụ.Sulfur vulcanized butyl roba nwere ike iji na ikuku ruo ogologo oge na 100 ℃ ma ọ bụ dịtụ ala okpomọkụ.Okpomọkụ ọrụ butyl roba vulcanized na resin nwere ike iru 150-200 ℃.The thermal oxygen ịka nká nke butyl rubber bụ ụdị mmebi, na ịka nká na-adịkarị nro.N'ihi enweghị unsaturation nke molekụla yinye butyl roba na mmeghachi omume kemịkalụ inert, butyl roba nwere ezigbo okpomọkụ na ikuku oxygen na-eguzogide ịka nká.
