ʻO ka lāʻau silicone vulcanized lumi wela, i hoʻopau ʻia e like me ka lāʻau wela lumi, he elastomer organosilicon i puka mai i ka makahiki 1960. ʻO ka hiʻohiʻona kaulana loa o kēia lāʻau lapaʻau ʻo ia ka hiki ke ho'ōla ma ka lumi wela me ka ʻole o ka hoʻomehana ʻana a i ʻole kaomi ʻana, e maʻalahi loa ia e hoʻohana. No laila, ua ulu wikiwiki mai kona hoʻomaka ʻana. E like me -ka wela wela, ka lumi -mamahana silikoni pulupulu pulupulu i haku ia me ka pulupulu kumu, ka hoopiha piha ana, ka mea hookui kea, catalysts a me na mea hoohui. ʻOi aku ka haʻahaʻa o ke kaumaha molekala o ka polymer i hoʻohana ʻia ma ke ʻano o ke kāpili kumu ma mua o ka polymer i hoʻohana ʻia no ka hana ʻana i ke kolu wela kiʻekiʻe. Ma muli o ke ʻano, hiki ke hoʻokō ʻia ka vulcanization o ka lumi -mahana lāʻau ma o ka condensation/decomposition a i ʻole ka hoʻohui ʻana o nā pūʻulu ikaika.
E like me ka vulcanization reaction mechanism, hiki ke māhele 'ia ka lumi -mea wela i nā 'ano synthetic a me nā 'ano ho'ohui, a ma muli o ke 'ano o ka pu'upu'u a me ka waiho 'ana, hiki ke ho'oka'awale 'ia i ho'okahi -'āpana a me 'elua-'ano mea. Hoʻokahi-mea hoʻopaʻapaʻa vulcanizing ʻano ʻano condensation, ʻoiai ʻelua-ʻano pahu wela lumi he ʻelua ʻano: ʻano condensation a me ke ʻano hoʻohui.
