Ho hanyetsa ho bola ha thepa e tloaelehileng ea li-valve-- Rabara ea tlhaho

Rabara ea tlhaho Rabara ea tlhaho ea tlhaho ke mofuta oa tlhaho ea tlhaho e phahameng ea molek'hule e nang le polyisoprene e le karolo e ka sehloohong. Mokhoa oa eona oa molek'hule ke (c5h8) n. 91% ~ 94% ea likarolo tsa eona ke rabara ea hydrocarbons (polyisoprene), 'me tse ling ke lintho tseo e seng rabara tse kang protheine, mafura a acid, molora, tsoekere, joalo-joalo. Rabara ea tlhaho ke rabara e akaretsang e sebelisoang ka ho fetisisa. Corrosion resistance E na le elasticity e phahameng le polasetiki e nyane mochesong oa kamore, 'me ea kristale le ho thatafala ka mocheso o tlase. E na le khanyetso e ntle ea alkali, empa ha e matla ho hanyetsa acid. Ha e qhibilihe ka metsing, li-ketones tse tlase le lino tse tahang, 'me e ka ruruha ka har'a metsoako e se nang polar e kang chloroform le carbon tetrachloride.
