ʻO mākou ʻo Shanghai Theorem Chemical i hoʻopaʻa ʻia i nā mea kemika hou, Polyurethane raw material a me nā isocyanates kūikawā, I nā makahiki, i ka ʻikepili o "Quality Oriented, Technology Guided", ua hoʻomohala ka hui e like meIsocyanate RE,RFE,1,5-Naphthalene Diisocyanate(NDI),PPDI (1,4-Phenylene Diisocvanate), etc…
ʻO mākou ka mea hoʻolako kiʻekiʻe o NDI (1,5-naphthalene diisocyanate) ma Kina, me ka maʻemaʻe kiʻekiʻe 99% min a me ke kumukūʻai hoʻokūkū, ʻo kā mākou NDI he ʻano polyurethane (PU) synthesized e diisocyanate. Ke hoʻohālikelike ʻia me MDI a me TDI, NDI me ka helu hoʻoheheʻe kiʻekiʻe, ka rigidity molecular kiʻekiʻe, ka maʻamau, a me ka symmetry, hiki ke hoʻomaikaʻi i ke ʻano o ka hoʻokaʻawale ʻana o ka polyurethane, me ka loaʻa ʻana o ka polyurethane ma muli o NDI i ʻoi aku ka maikaʻi o nā waiwai mechanical a me ke kino. ʻO ka polyurethane i hoʻokumu ʻia i ka NDI he kūpaʻa ʻaʻahu kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion a me nā waiwai hoʻoikaika maikaʻi loa, a hoʻohana nui ʻia i nā manawa hoʻokūkū kiʻekiʻe.
ʻO NDI (1,5-Naphthalene Diisocyanate) kahi mea maka o ka polyurethane kiʻekiʻe, hiki ke hoʻohana ʻia e hana i ka polyurethane elastomer me ka elasticity kiʻekiʻe a me ka paʻakikī kiʻekiʻe. He hana maikaʻi loa ka NDI polyurethane elastomer. Loaʻa iā ia ka hana like ʻole me nā elastomer polyurethane ʻē aʻe, e like me ka hana hoʻoikaika maikaʻi loa, ka hana mechanical kiʻekiʻe loa, ke kūpaʻa ʻoki maikaʻi loa, ka pale ʻana i ka lole a me ke kūpaʻa wela. No laila, hoʻohana nui ʻia ka NDI polyurethane elastomers i nā mea hoʻoheheʻe kaʻa, nā huila forklift, ka paʻi ʻana a me ka waihoʻoluʻu ʻana i nā wili lole lole, nā ʻōpala ʻōpala, nā poloka pale kūkulu alahaka, nā ʻoihana koa, etc.
