Hiki ke hoʻokaʻawale ʻia i ʻelua waeʻano nui ma muli o ke ʻano hana vulcanization: ka vulcanization peroxide a me ka vulcanization hoʻohui.
I kēia manawa, ʻo ka peroxide vulcanized rubber no ka hapa nui o ka -pelepa wela kiʻekiʻe. Loaʻa i ka peroxide vulcanization ka maikaʻi o ke kumukūʻai haʻahaʻa a me ka hilinaʻi, akā he nui nā hemahema, e like me ka melemele ma hope o ka vulcanization, ʻala i ka wā o ka hana ʻana, ke koena o ka peroxide i ka lāʻau, stickiness ma ka ʻili o ka huahana, a me ke komo ʻana o nā huahana decomposition peroxide i ka lewa.
Ua lanakila ka hoʻohui vulcanization i nā hemahema a pau-i ʻōlelo ʻia ma luna nei, no laila ua hoʻohui ʻia ka hapa nui o nā huahana lapaʻau.
