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 katoloso ea ketane bakeng sa li-elastomer tsa polyurethane le e le moemeli oa ho folisa resin ea epoxy ho ntlafatsa thepa ea mechini le ea matla ea lihlahisoa. MED e ka boela ea sebelisoa e le motsoako o etellang pele bakeng sa li-polyimide le e le mokena-lipakeng bakeng sa tlhahiso ea lintho tse phelang.
E loketse hantle bakeng sa ho etsa polyurethane (CPU), thermoplastic polyurethane (TPU), RIM elastomers le spray polyurea tšimong ea polyurethane. MED e boetse e sebetsa bakeng sa ho sebetsana le ho roala, ho lokisa pele le lik'hemik'hale tse thibelang ho bola tšimong ea resin ea epoxy. MED e sebelisoa ho kopanyeng li-prepolymers, ho kenyeletsoa polyether le polyester.
MED ke tharollo e phethahetseng bakeng sa lihlahisoa tse felileng tse hlokang 'mala o bobebe le ho thibela botsofali. MED e ka sebelisoa le metsoako e meng ea ho phekola ea mofuta oa amine (motsoako) ho fihlela litšobotsi tse betere tsa 'mele.
MED le MOCA ka bobeli ke dihlahiswa tse phekolang tsa mofuta wa amine. Leha ho le jwalo, MED e mosa tikolohong mme ha e silafala hakaalo ha e bapiswa le MOCA. MED e ka boela ya nkela MBOEA le HQEE sebaka dihlahisweng tsa PU, ho sa tsotelehe CPU (casting polyurethane) kapa TPU (thermoplastic polyurethane). Jwalo ka MOCA, di-elastomer tsa mofuta wa MED di na le kganyetso e ntle ya mocheso e hlokang ho sebediswa ka nako e fetang 120℃.
MED/MMEA ke sehokelo sa diamine sa ketane e nkhang hamonate le moemeli oa ho folisa. Ka lebaka la melao e thata ea ho sebelisa MOCA, MED e mosa tikolohong, e sa silafatsoang ke khetho e 'ngoe e ntle e sebelisoang lits'ebetsong tse fapaneng. Li-polyurethane tsa MED-base li na le mekhoa e mengata le bolokolohi ba moralo, li na le thepa e matla ha li ntse li boloka ho tenyetseha ha tsona.
