SIS(Styrene-isoprene-styrene poloka copolymer)
Baling Petrochemical SIS o le styrene - isoprene poloka copolymer i foliga o le paʻepaʻe porous particle po o translucent compact particle, faatasi ai ma foliga o le thermo-plasticity lelei, elasticity maualuga, suavai liusuavai lelei, fetaui lelei ma tackifying resin, saogalemu ma le oona.E mafai ona faʻaaogaina i mea faʻapipiʻi vevela vevela, sima solvent, fetuutuunai lomitusi papatusi, palasitika ma le asphalt fesuiaiga, ma o le mea sili ona lelei o mea faʻapipiʻi faʻaaogaina e gaosia ai ato faʻapipiʻi, sapalai tumama, faʻamau faʻapipiʻi lua itu ma igoa. .
MEATOTOGA MA FA'AGAGA
Styrene-isoprene poloka copolymers (SIS) o le tele o voluma, taugofie pisinisi thermoplastic elastomers (TPE) lea e gaosia e ala i le ola ionic copolymerization e ala i sequentially faailoa styrene, 2-methyl-1,3-butadiene (isoprene), ma styrene i le reactor. .Ole mea ole styrene e masani ona eseese ile va ole 15 ma le 40 pasene.A mālūlū i lalo ole mea liusuavai, o le SIS e iai se vaega maualalo o le styrene i totonu o le va'aiga-vavae i totonu o le nano-sized polystyrene spheres fa'apipi'i i totonu o le isoprene matrix ae o le fa'ateleina o le styrene mea e tau atu i le cylindrical ona sosoo ai lea ma fausaga lamellar.O vaega styrene malo e galue e pei o feso'ota'iga fa'aletino e maua ai le malosi fa'ainisinia ma fa'aleleia atili ai le fa'asao, ae o le isoprene rubber matrix e maua ai le fetu'una'i ma le faigata.O mea fa'ainisinia o SIS elastomers ma le maualalo o le styrene mea e tutusa ma pa'u vulcanized.Ae ui i lea, e le pei o le paʻu vulcanized, SIS elastomers e mafai ona faʻaogaina i meafaigaluega e faʻaaogaina mo le gaosia o polymers thermoplastic.
SIS poloka copolymers e masani ona faʻafefiloi ma tackifier resins, suauʻu ma faʻatumu, lea e mafai ai mo se suiga tele o meatotino oloa poʻo latou faʻaopoopo i isi polymers thermoplastic e faʻaleleia ai a latou faʻatinoga.
SIS copolymers o loʻo faʻaaogaina lautele i mea faʻapipiʻi vevela, faʻamaufaʻailoga, mea paʻu, paʻu paʻu, meataalo meataalo, seevae seevae ma oloa bitumen mo le faʻaogaina o auala ma faʻaoga taualuga.O lo'o fa'aaogaina fo'i e fai ma suiga o a'afiaga ma fa'amalosi i palasitika ma mea fa'apipi'i.
