SIS(Styrene-isoprene-styrene block copolymer)
Baling Petrochemical SIS ke styrene - isoprene block copolymer ka sebopeho sa porous particle e tšoeu kapa translucent compact particle, e nang le likarolo tse ntle tsa thermo-plasticity, elasticity e phahameng, metsi a qhibilihisang hantle, a lumellana hantle le resin ea tackifying, e bolokehileng le e seng chefo.E ka sebelisoa ho li-adhesives tse mamellang khatello e chesang e qhibilihang, lisamente tse qhibilihang, lipoleiti tsa khatiso tse feto-fetohang, lipolasetiki le phetoho ea sekontiri, 'me ke lisebelisoa tse ntle tsa likhomaretsi tse sebelisetsoang ho etsa mekotla ea ho paka, lisebelisoa tsa likhoerekhoere, litheipi tse khomaretsang tse mahlakoreng a mabeli le mangolo. .
LETLOTLO LE LIKOPO
Styrene-isoprene block copolymers (SIS) ke molumo o moholo, li-elastomers tsa thermoplastic tsa theko e tlase (TPE) tse hlahisoang ke li-ionic copolymerization ka ho hlahisa styrene ka tatellano, 2-methyl-1,3-butadiene (isoprene), le styrene ho reactor. .Lintho tsa styrene hangata li fapana pakeng tsa 15 le 40 lekholong.Ha e pholisitsoe ka tlas'a ntlha ea ho qhibiliha, li-SIS tse nang le likarolo tse tlaase tsa styrene li arohanngoa ka likaroloana tsa nano-size polystyrene tse kenngoeng ka har'a matrix ea isoprene athe ho eketseha ha lintho tsa styrene ho lebisa ho cylindrical le ho li-lamellar.Libaka tse thata tsa styrene li sebetsa e le li-crosslink tsa 'mele tse fanang ka matla a mochine le ho ntlafatsa ho hanyetsa ha abrasion, ha matrix ea rabara ea isoprene e fana ka phetoho le boima.Thepa ea mochini ea li-elastomer tsa SIS tse nang le li-styrene tse tlase li ts'oana le tsa liraba tse hlasetsoeng.Leha ho le joalo, ho fapana le rabara e chesitsoeng, li-elastomer tsa SIS li ka sebetsoa ka lisebelisoa tse sebelisetsoang ho etsa lipolyme tsa thermoplastic.
Hangata li-copolymers tsa SIS li kopantsoe le li-resin tsa tackifier, oli le li-filler, tse lumellang hore ho be le phetoho e fapaneng ea thepa ea sehlahisoa kapa li eketsoa ho lipolymer tse ling tsa thermoplastic ho ntlafatsa ts'ebetso ea tsona.
Li-copolymers tsa SIS li sebelisoa haholo ho li-adhesives tse chesang, li-sealants, lisebelisoa tsa gasket, lihlopha tsa rabara, lihlahisoa tsa lipapali, lieta le lihlahisoa tsa bitumen bakeng sa ho betla litsela le ho rulela.Li boetse li sebelisoa e le li-modifiers le li-tougheners ka har'a lipolasetiki le likhomaretsi (tsa sebopeho).
