Inkqubo yoKhuseleko yePU
Inkqubo yoKhuseleko yePU
IUkuzala
Inkqubo ye-PU ngokhuseleko isetyenziselwa ukwenza iziqhulo zokhuseleko kunye nezihlobo zangaphakathi. Yinkqubo ye-POLYEST-esekwe kwi-PUSEST, inezinto ezine, iPolyol, i-ISO, i-Harner kunye neNtloko. Ukulungiswa kwenkqubo ngamacandelo amabini. I-Catalyst, i-terder, iarhente kunye ne-pigment kufuneka ixutywe ngokucokisekileyo kunye necandelo lePolyl-3270A, emva koko uxube neCandelo Exd-3119b ngokwenza izinto zokugqibela.
