Litšobotsi tsa fisicochemical: e tšoeu ho isa ho e mosehla o bobebe, e tiileng ea kristale e qhibilihisang. Sebaka sa ho qhibiliha: 126-130 °C, ntlha ea ho belisa: 167 °C (5 × 1.33kPa), bongata: 1.42-1.45g/cm3
1,5-naphthalene diisocyanate (NDI) ke mofuta oa polyurethane (PU) e entsoeng ke diisocyanate. Ha e bapisoa le MDI le TDI, NDI e nang le ntlha e phahameng ea ho qhibiliha, ho tiea ha limolek'hule tse phahameng, ho nepahala le ho se leka-lekane, e leng se ka ntlafatsang ka botlalo tekanyo ea karohano ea karolo ea polyurethane, e leng se etsang hore polyurethane e thehiloeng ho NDI e be le thepa e ntle haholo ea mechini le ea 'mele. Polyurethane e thehiloeng ho NDI e na le khanyetso e phahameng ea ho tsofala, khanyetso e phahameng ea mocheso, khanyetso ea mafome le thepa e ntle ea matla, 'me e sebelisoa haholo-holo liketsahalong tse matla tsa moroalo o matla le khanyetso ea mocheso.
NDI (1,5-Naphthalene Diisocyanate) ke thepa e tala ea polyurethane e tsoetseng pele, e ka sebelisoang ho etsa polyurethane elastomer e nang le ho tenyetseha ho hoholo le ho ba thata haholo. NDI polyurethane elastomer e na le ts'ebetso e ntle haholo. E na le ts'ebetso e ke keng ea bapisoa le polyurethane elastomer efe kapa efe, joalo ka ts'ebetso e ntle haholo ea matla, ts'ebetso e phahameng haholo ea mechini, khanyetso e ntle ea ho seha, khanyetso ea ho tsofala le khanyetso ea mocheso. Ka hona, NDI polyurethane elastomers li sebelisoa haholo ho li-absorber tsa ho tšoha ha likoloi, mabili a bearing forklift, li-roller tsa rabara tsa masela tse hatisoang le tse dailoeng, li-scraper tsa rabara, li-buffer block tsa kaho ea borokho, indasteri ea sesole, jj.
Elastomer e ka lahloang e entsoeng ke NDI e na le litšobotsi tse ntle tsa matla le ho hanyetsa ho tsofala, 'me e na le mongobo o monyane, ho mamella ho hoholo, le mocheso o fokolang oa ka hare. E ka sebelisoa maemong a boima ba matla le ho hanyetsa mocheso. Lihlahisoa tse bōpiloeng tse entsoeng ka NDI li na le matla a ho taboha ho hoholo, ho taboha ho tlase, sete e tlase ea khatello le ho mamella ho hoholo. Lihlahisoa tsa elastomer tsa polyurethane tse nang le li-microporous tse thehiloeng ho NDI li na le mocheso o tlase oa tlhaho, ho fetoha ho honyenyane ha kamehla le ho tiea ho hotle tlas'a mojaro o matla. Thepa ena e khethehileng ea polyurethane e nang le li-microporous e sebelisoa haholo bakeng sa ho monya le ho robeha ha koloi.
