Product Overview
1,3-Butadiene yog ib qho reactive conjugated diene nrog ob carbon-carbon ob daim ntawv cog lus sib cais los ntawm ib daim ntawv cog lus. Nws yog ib qho tsis muaj xim, nplaim hluav taws xob nrog cov ntxhiab tsw me me thiab ua haujlwm tseem ceeb hauv kev tsim cov roj hmab hluavtaws thiab cov polymers. Raws li lub tuam tsev petrochemical tseem ceeb, 1,3-butadiene feem ntau yog muab los ntawm chav tawg ntawm hydrocarbons thiab yog qhov tseem ceeb rau kev tsim cov elastomers nrog zoo heev resilience thiab durability. Nws cov qauv tshuaj tshwj xeeb ua rau muaj ntau yam polymerization thiab copolymerization, ua rau nws tseem tsis tau muaj nyob rau hauv cov roj hmab, plastics, thiab automotive industries.

Nta & Qhov Zoo
High Reactivity rau Polymerization
Lub conjugated diene qauv ntawm 1,3-butadiene tso cai rau nws nkag mus rau hauv kev ntxiv polymerization thiab copolymerization, tsim ntev polymer chains nrog elastomeric zog.
Versatile Monomer rau Synthetic Rubbers
Nws yog thawj monomer rau kev tsim cov styrene-butadiene roj hmab (SBR), polybutadiene roj hmab (BR), thiab nitrile roj hmab (NBR), uas sib sau ua ke rau feem ntau ntawm cov khoom siv hluavtaws thoob ntiaj teb.
Zoo heev Elasticity thiab Resilience
Polymers muab tau los ntawm 1,3-butadiene qhia tau zoo heev yooj yooj yim, abrasion kuj, thiab qis-kub kev ua tau zoo, ua rau lawv zoo tagnrho rau dynamic daim ntaub ntawv.
Compatibility nrog lwm cov Monomers
Nws tuaj yeem ua copolymerized nrog styrene, acrylonitrile, thiab lwm yam monomers los txiav cov khoom siv rau kev siv tshwj xeeb.
Cov yam ntxwv ua haujlwm
Polymerization cwj pwm
1,3-Butadiene tuaj yeem ua polymerize ntawm dawb-radical, anionic, los yog kev sib koom ua ke mechanisms los tsim cis-, trans-, lossis yas configurations, cuam tshuam rau cov khoom siv polymer kawg.
Tshuaj Reactivity
Ntxiv rau polymerization, nws koom nrog Diels-Alder cov tshuaj tiv thaiv, hydrogenation, thiab halogenation, ua tus thawj coj rau ntau yam tshuaj nruab nrab.
Stabilization thiab tuav
Vim nws nyiam tsim peroxides thiab polymerize explosively, nws yuav tsum tau muab khaws cia nrog inhibitors thiab nyob rau hauv kev tswj tej yam kev mob (feem ntau refrigerated) kom muaj kev ruaj ntseg.

Cov neeg siv khoom sib koom tes Case
Ib lub tuam txhab ua lag luam log tsheb tau nrhiav los txhim kho qhov tuav ntub thiab dov tsis kam ntawm lawv cov log tsheb hwm zoo yam tsis muaj kev cuam tshuam ntev. Lawv koom tes nrog peb pab neeg los txhim kho 1,3-butadiene cov ntsiab lus thiab microstructure hauv lawv cov qauv SBR. Los ntawm leveraging peb siab -purity 1,3-butadiene (Ntau dua los yog sib npaug rau 99.7%) thiab tailored polymerization technology, peb tsim ib tug customized SBR nrog optimized tshuav nyiaj li cas ntawm yas thiab cis{18}}1,4 configurations. Qhov no ua rau muaj 15% kev txhim kho hauv kev ntub dej thiab 10% txo qis hauv kev ua haujlwm dov, ua rau kom muaj roj zoo dua thiab kev nyab xeeb. Qhov zoo ib yam ntawm peb cov 1,3-butadiene tau ua kom muaj kev sib tw-rau-batch, ua rau cov neeg siv khoom ua tau raws li cov qauv kev lag luam tsheb nruj thiab ntxiv dag zog rau lawv txoj kev lag luam hauv cov log tsheb ua haujlwm siab.
