4,4′-Methylenebis(2-ethyl-6-methylaniline) / MMEA CAS No. 19900-72-2
4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA, nomoro ea CAS 19900-72-2, e sebelisoa e le ketane ea ketane bakeng sa polyurethane elastomers le e le moemeli oa phekolo bakeng sa epoxy resin ho ntlafatsa thepa ea mechine le e matla. ea lihlahisoa. MED e ka boela ea sebelisoa e le motsoako o ka sehloohong oa polyimides le e le mokena-lipakeng oa motsoako oa manyolo.
E loketse hantle bakeng sa ho lahlela polyurethane (CPU), thermoplastic polyurethane (TPU), RIM elastomers le spray polyurea tšimong ea polyurethane. MED e boetse e sebetsa bakeng sa ho lokisa, prepreg le lik'hemik'hale tse thibelang likokoana-hloko tšimong ea epoxy resin. MED e sebelisoa ha ho etsoa li-prepolymers, ho kenyelletsa le polyether le polyester.
MED ke tharollo e loketseng bakeng sa lihlahisoa tse feliloeng tse hlokang 'mala o bobebe le anti-botsofali. MED e ka sebelisoa le lisebelisoa tse ling tsa mofuta oa amine (motsoako) ho kopana le thepa e ntle ea 'mele.
MED le MOCA ka bobeli ke mefuta ea amine e phekolang. Leha ho le joalo, MED e sebelisana le tikoloho ebile ha e silafale hakaalo ha e bapisoa le MOCA. MED e ka boela ea nka sebaka sa MBOEA le HQEE ho lihlahisoa tsa PU, ho sa tsotellehe CPU (casting polyurethane) kapa TPU (thermoplastic polyurethane). E ts'oanang le MOCA, li-elastomer tsa mofuta oa MED li na le ts'ebetso e ntle ea ho hanyetsa mocheso e batlang ho sebetsa ho feta 120 ℃.
