SIS (Styrene-isoprene-styrene block copolymer)
Baling Petrochemical SIS yog styrene - isoprene thaiv copolymer nyob rau hauv daim ntawv ntawm dawb porous particle los yog translucent compact particle, nrog cov yam ntxwv ntawm zoo thermo-plasticity, siab elasticity, zoo yaj fluidity, zoo compatibility nrog tackifying resin, muaj kev nyab xeeb thiab tsis muaj tshuaj lom.Nws tuaj yeem siv rau cov nplaum kub-melt-sensitive-sensitive adhesives, hnyav cements, hloov tau yooj yim luam ntawv daim hlau, yas thiab asphalt hloov kho, thiab yog cov khoom siv zoo tshaj plaws ntawm cov nplaum siv los tsim cov hnab ntim khoom, cov khoom siv huv huv, ob-sided adhesive tapes thiab cov ntawv lo. .
PROPERTIES THIAB APPLICATIONS
Styrene-isoprene block copolymers (SIS) yog cov ntim loj, tus nqi qis ua lag luam thermoplastic elastomers (TPE) uas yog tsim los ntawm kev ua neej nyob ionic copolymerization los ntawm kev qhia styrene, 2-methyl-1,3-butadiene (isoprene), thiab styrene rau hauv lub reactor. .Cov ntsiab lus styrene feem ntau txawv ntawm 15 thiab 40 feem pua.Thaum txias hauv qab lub melting point, SIS's nrog cov ntsiab lus qis styrene theem-sib cais rau hauv nano-loj polystyrene spheres imbedded nyob rau hauv ib qho isoprene matrix whereas qhov nce ntawm cov ntsiab lus styrene ua rau cylindrical thiab ces mus rau lamellar qauv.Lub zog styrene domains ua haujlwm raws li lub cev crosslinks uas muab cov cuab yeej siv zog thiab txhim kho kev puas tsuaj, thaum lub isoprene roj hmab matrix muab kev yooj yim thiab tawv.Cov cuab yeej cuab tam ntawm SIS elastomers nrog cov ntsiab lus styrene tsawg zoo ib yam li cov roj hmab vulcanized.Txawm li cas los xij, tsis zoo li cov roj hmab vulcanized, SIS elastomers tuaj yeem ua tiav nrog cov cuab yeej siv rau fabricating thermoplastic polymers.
SIS block copolymer feem ntau sib xyaw nrog tackifier resins, roj thiab muab tub lim, uas tso cai rau kev hloov pauv ntau yam ntawm cov khoom lag luam lossis lawv ntxiv rau lwm cov thermoplastic polymers los txhim kho lawv cov kev ua tau zoo.
SIS copolymer yog dav siv nyob rau hauv hotmelt adhesives, sealants, gasket cov ntaub ntawv, roj hmab band, khoom ua si, khau khau thiab nyob rau hauv bitumen cov khoom rau txoj kev paving thiab vov tsev daim ntaub ntawv.Lawv kuj tau siv los ua kev hloov pauv thiab tougheners hauv plastics thiab (structural) adhesives.
