Pyromellitic dianhydride (PMDA)
Pyromellitic Anhydride (PMDA) yog cov khoom siv raw rau cov khoom siv hluav taws xob tiv thaiv polyimide resins, films thiab coatings.
PMDA feem ntau yog siv los ua ib qho nruab nrab rau cov yeeb yaj kiab polyimide nrog rau cov khoom siv polyimide hauv cov ntawv luam tawm yooj yim, daim kab xev automated bonding, sib nqus hlau rwb thaiv tsev, thiab lwm yam.
kev ua haujlwm siab.
Nws kuj tseem siv tau los ua tus neeg sawv cev kho rau epoxy resins siv hauv cov hmoov molding (los tsim cov khoom siv rau cov hlua khi, cov tshuab ntxhua khaub ncaws, cov khoom siv tshwj xeeb lossis cov thermal thiab hluav taws xob insulators), cov nplaum thiab cov coatings.
Shanghai Runwu Chemical Technology Co. Ltd yog cov khoom lag luam tshuaj lom neeg R & D, ntau lawm, kev muag khoom, ua ib qho ntawm kev tshawb nrhiav.Peb nyob ntawm kev muaj peev xwm tshawb fawb muaj zog thiab paub tab technology, muaj kev nce siab hauv kev lag luam tshuaj, vam khom rau kev tshawb fawb thiab thev naus laus zis, muab cov neeg siv khoom zoo tshaj plaws yog peb qhov kev nrhiav tsis tu ncua.
Peb tsuas yog cuam tshuam nrog cov organic intermediates, noble hlau catalyst, cov ntaub ntawv nano, tsis tshua muaj ntiaj teb.Cov ntaub ntawv no tau siv dav hauv chemistry, tshuaj, biology, kev tiv thaiv ib puag ncig, lub zog tshiab, thiab lwm yam.
Nrog thawj cov khoom lag luam zoo thiab cov kev pabcuam zoo tshaj plaws, Peb tau txais kev qhuas ntawm kev lis kev cai.Nyob rau tib lub sijhawm, hauv kev txhim kho, peb lub tuam txhab ua raws li kev koom tes nrog cov tuam txhab hauv tsev thiab txawv teb chaws, cov chaw tshawb fawb tshawb fawb, kev sib pauv hauv tsev kawm qib siab, txhawm rau txhim kho R & D thiab muaj peev xwm ntau lawm, cog lus los muab cov neeg siv khoom nrog cov khoom zoo thiab cov kev pabcuam.
