Holim'a moo:Khamphani e ka etsa lipatlisiso le ho nts'etsapele lihlahisoa tse ncha ho latela tlhoko e khethehileng ea bareki ba rona.
Likaroloana:RFE polyisocyanate ke sefapano se sebetsang hantle haholo bakeng sa likhomaretsi tse thehiloeng ho polyurethane, rabara ea tlhaho le rabara ea Synthesis. RFE polyisocyanate e boetse e thusa ho ntlafatsa ho khomarela lisebelisoa tse thehiloeng ho rabara. E ka sebelisoa e le crosslinker sebakeng sa Bayer's Desmodur RFE.
