Pyromellitic dianhydride (PMDA)
Pyromellitic Anhydride (PMDA) ndi zinthu zopangira ma resins a polyimide osamva kutentha, mafilimu ndi zokutira.
PMDA imagwiritsidwa ntchito makamaka ngati gawo lapakati pamakanema a polyimide komanso zida zophatikizika za polyimide m'ma board osinthika osindikizira, tepi yolumikizira makina, kutsekereza waya wamagetsi, ndi zina.
ntchito zapamwamba.
Amagwiritsidwanso ntchito ngati mankhwala ochizira resins epoxy ntchito akamaumba ufa (kupanga zigawo zikuluzikulu kwa mphete chisindikizo, thrust washers, gaskets wapadera kapena matenthedwe ndi magetsi insulators), zomatira ndi zokutira.
Shanghai Runwu Chemical Technology Co. Ltd ndi mankhwala ogwira ntchito R & D, kupanga, malonda, monga chimodzi mwa zidziwitso.Timadalira luso lamphamvu la kafukufuku ndi ukadaulo wokhwima, kukwera mwachangu kwamakampani opanga mankhwala, kudalira sayansi ndi chitukuko chaukadaulo, kupatsa makasitomala zinthu zamtengo wapatali ndizochita zathu zonse.
Timachita makamaka ndi organic intermediates, wolemekezeka zitsulo chothandizira, nano zipangizo, osowa lapansi.Zidazi zimagwiritsidwa ntchito kwambiri mu chemistry, mankhwala, biology, kuteteza chilengedwe, mphamvu zatsopano, ndi zina zotero.
Ndi mtundu woyamba wazinthu komanso ntchito zapamwamba kwambiri zaukadaulo, Tapambana kutamandidwa kwa miyambo.Pa nthawi yomweyi, mu chitukuko, kampani yathu amatsatira mgwirizano ndi makampani zoweta ndi akunja, mabungwe kafukufuku sayansi, mayunivesite kuwombola, kuti apititse patsogolo R & D ndi mphamvu kupanga, odzipereka kupereka makasitomala ndi zinthu zambiri khalidwe ndi ntchito.
