Tolidine diisosianati TODI / 3,3′-Dimethyl-4,4′-biphenylene diisosianati CAS NO. 91-97-4

TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, inomero ya CAS 91-97-4, ni inyongeramusaruro rusange yo kunoza imiterere ya mekanike n'iya chimique kuri elastomer za urethane. Impeta ebyiri za benzene muri molekile ya TODI zifite imiterere ingana. Bitewe n'imbogamizi za o-methyl, imikorere y'imyakura iri hasi ugereranyije n'iya TDI na MDI.

Ugereranyije na elastomeri za polyurethane zishingiye kuri NDI, elastomeri zishingiye kuri TODI, oligomer polyols na MOCA zifite imiterere isa, nko kurwanya ubushyuhe neza, kurwanya hidrolisiyusi n'imiterere ya mekanike. Ugereranyije na rubbers, pulasitiki n'ibyuma, elastomeri zishingiye kuri TODI zifite ibyiza byinshi, ziraramba, zirwanya ubushyuhe kandi zirwanya hidrolisiyusi. Elastomeri zishingiye kuri TODI zitanga imiterere myiza ya mekanike ikoreshwa mu gihe ikora mu bihe bikomeye cyangwa mu bidukikije. Byongeye kandi, bitewe n'igihe kirekire cyo kumara igihe kinini mu nkono, prepolymer ishingiye kuri TODI yoroshye kuyitwara ugereranije n'ibicuruzwa bishingiye kuri NDI.
