4,4′-Methylenebis(2-ethyl-6-methylaniline) / MMEA CAS No. 19900-72-2

4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA, lambarka CAS 19900-72-2, waxaa loo isticmaalaa sidii fidsan silsilad loogu talagalay elastomer-ka polyurethane iyo sidii wakiil bogsiin ah oo loogu talagalay epoxy resin si loo hagaajiyo sifooyinka farsamada iyo firfircoonida ee alaabada. MED sidoo kale waxaa loo isticmaali karaa sidii isku-darka hormuudka u ah polyimides iyo dhexdhexaadin loogu talagalay isku-darka dabiiciga ah.

Si fiican ugu habboon polyurethane (CPU), thermoplastic polyurethane (TPU), RIM elastomers iyo buufin polyurea ah oo ku taal goobta polyurethane. MED sidoo kale waxay khuseysaa habaynta, diyaarinta iyo dahaarka kiimikada ee ka hortagga daxalka ee goobta resin epoxy. MED waxaa loo isticmaalaa isku-darka prepolymers, oo ay ku jiraan polyether iyo polyester.

MED waa xal ku habboon alaabada la dhammeeyay ee u baahan midab khafiif ah iyo ka hortagga gabowga. MED waxaa lagu mari karaa wakiilada kale ee daaweynta nooca amine-ka (isku-darka) si loo daboolo sifooyinka jireed ee wanaagsan.

MED iyo MOCA labaduba waa wakiilo daaweyn nooca amine ah. Si kastaba ha ahaatee, MED waa mid deegaanka u fiican oo aan wasakh badnayn marka la barbar dhigo MOCA. MED sidoo kale waxay beddeli kartaa MBOEA iyo HQEE alaabada PU, iyadoon loo eegin CPU (polyurethane shubidda) ama TPU (polyurethane thermoplastic). Sida MOCA oo kale, ELASTORM-ka nooca MED waxay leeyihiin iska caabin kulayl oo aad u fiican marka ay ka shaqeeyaan heerkul ka badan 120℃.
