Tšebeliso
polyisobutene (hydrogenated) ke ntho e thobang letlalo.
Polyisobutylene, eo ka linako tse ling e bitsoang rabara ea butyl, 'me ka linako tse ling PIB, ke polymer ea vinyl. E tšoana haholo le polyethylene le polypropylene ka sebopeho, ntle le hore khabone e 'ngoe le e 'ngoe e nkeloa sebaka ke lihlopha tse peli tsa methyl. E entsoe ka isobutylene ea monomer, ka polymerization ea cationic vinyl.
Polyisobutylene ke rabara ea maiketsetso, kapa elastomer. E ikhetha hobane ke rabara feela e sa keneng ka khase. Ke hore, ke rabara feela e ka tšoarang moea nako e telele. Mohlomong u hlokometse hore libalune li tla fola kamora matsatsi a 'maloa. Lebaka ke hobane li entsoe ka polyisoprene, e seng khase e sa keneng ka eona. Hobane polyisobutylene e tla tšoara moea, e sebelisoa ho etsa lintho tse kang lipeipi tsa ka hare, likarolo tsa liner tsa mabili, le liner tsa ka hare tsa basketball.
