POLYMERIKA MDI
Na waiwai nui a me na noi
ʻO POLYMORIC MDI kahi hui wai ʻeleʻele-ʻeleʻele o diphenylmethane-4,4′-diisocyanate (MDI) me ka isomer a me nā homologues o ka hana kiʻekiʻe.Hoʻohana pū ʻia me nā polyols e hana i ka huʻa polyurethanes paʻa.

Cyclopentane
ʻO Cyclopentane, i kapa ʻia ʻo "pentamethylene", he ʻano cycloalkane me ke ʻano o C5H10.He 70.13 kona kaumaha mole.Aia ma ke ʻano he ʻano wai wela.Hiki ke hoʻoheheʻe ʻia i ka waiʻona, ka ether a me ka hydrocarbons a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai.ʻAʻole ʻo Cyclopentane he apo planar a he ʻelua conformations: conformation envelope a me semi-chair conformations.Hōʻike ia i ka waihoʻoluʻu melemele ʻulaʻula i ka wā e pane ai me ka ʻakika sulfuric fuming ʻoiai e hoʻopuka ana i ka nitro cyclopentane a me ka waika glutaric ma o ka pane ʻana me ka waikawa nitric.

ʻAi ahi no ka polyurethane rigid foam system TCPP
ʻO ka Flame Retardant TCPP, ka inoa kemika Tris (2-chloroisopropyl) Phosphate, he chlorine kumu kūʻai haʻahaʻa a me ka phosphorous ma muli o ka pale ahi.Loaʻa iā ia ka paʻa hydrolysis maikaʻi loa ma waena o nā phosphate organik halogenated i kēia manawa.ʻAʻole hiki ke hoʻoheheʻe i ka wai, hoʻoheheʻe i ka hapa nui o ka mea hoʻoheheʻe organik, a loaʻa ka launa maikaʻi me nā resins.Ke noi nei e like me ka Flame Retardant i ka hana ʻana i ka fiber acetate, polyvinyl-chloride, PU foams, EVA, nā mea phenolics.Ma waho aʻe o ka pale ʻana o ke ahi, hiki iā ia ke hoʻoikaika i ka pale ʻana i ka wai, ke kū ʻana o ka wela haʻahaʻa, ka hiki ke antistatic a me ka palupalu o nā mea.
