Pentamethyldiethylenetriamine CAS 3030-47-5
ʻO ka Pentamethydiethylenetriamine he wai ʻaʻole waihoʻoluʻu i ka melemele, hiki ke hoʻoheheʻe ʻia i ka wai. He mea hoʻoikaika ikaika ia no ka hopena polyurethane. Hoʻohana nui ia i ka hoʻoulu ʻana i ka puaʻa, a hoʻohana ʻia hoʻi e kaulike i ka hoʻoulu ʻana a me ka hopena gel. Hoʻohana nui ʻia ia i loko o nā ʻano polyurethane rigid foams, me ka polyisocyanurate sheet rigid foams. ʻO nā ʻano hana o ka pentamethyldiethylenetriamine me ka formaldehyde formic acid method a me ka formaldehyde hydrogenation method.
