Anaga kiimikooyinka Theorem ee Shanghai waxaa ka go'an walxo cusub oo kiimiko, Polyurethane ceeriin iyo isocyanates gaar ah, sanadihii la soo dhaafay, falsafada "Quality Oriented, Technology Hagaha", shirkaddu waxay soo saartay sidaIsocyanate RE,RFE,1,5-Naphthalene Diisocyanate(NDI),PPDI (1,4-Phenylene Diisocvanate)iwm..
Waxaan nahay alaab-qeybiyaha ugu sarreeya ee NDI (1,5-naphthalene diisocyanate) ee Shiinaha, oo leh nadiif sare 99% min iyo qiimo tartan ah, NDIyadu waa nooc ka mid ah polyurethane (PU) oo ay soo saartay diisocyanate. Marka la barbar dhigo MDI iyo TDI, NDI oo leh barta dhalaalaysa sare, qallafsanaanta molecular sare, joogtaynta, iyo summetry, taas oo asal ahaan wanaajin karta heerka kala-soocidda poliurethane, samaynta NDI-ku salaysan polyurethane helitaanka sifooyin farsamo iyo jireed aad u fiican. NDI-ku salaysan polyurethane waxay leedahay caabbinta xirashada sare, caabbinta kulaylka sare, caabbinta daxalka iyo sifooyin firfircoon oo aad u fiican, waxaana inta badan loo isticmaalaa culeyska dhaqdhaqaaqa sare iyo munaasabadaha caabbinta kulaylka.
NDI (1,5-Naphthalene Diisocyanate) waa walxo cayriin ah oo ah polyurethane horumarsan, kaas oo loo isticmaali karo in lagu soo saaro elastomer poliurethane leh barti sare iyo qallafsanaan sare. NDI elastomer polyurethane ayaa leh waxqabad aad u fiican. Waxay leedahay waxqabad aan la barbardhigi karin elastomer kasta oo kale oo poliurethane ah, sida waxqabadka firfircoon ee aad u fiican, waxqabadka farsamada oo aad u sarreeya, iska caabin goynta heersare ah, xirashada caabbinta iyo iska caabinta heerkulka. Sidaa darteed, NDI polyurethane elastomers waxaa si weyn loogu isticmaalaa absorbers shoogga baabuurta, forklift wheels, daabacaadda iyo rinjiyeynta rullaluistemadka caagga ah, xoqin caag, blocks dhismaha buundada, warshadaha militariga, iwm.
