Isicelo

I-PM-200 ingasetshenziswa kabanzi ekwenzeni i-polyurethane eqinile ye-foam insulation materials; Ingasetshenziswa futhi kumagwebu e-isocyanurate, okokunamathela, okunamathelayo, ukuxhunywa kwe-anti-seepage, amagwebu esakhiwo, amagwebu esikhumba abalulekile amancane, obhampa bezimoto, izingxenye zangaphakathi, amagwebu aqinile, ukhuni lokwenziwa nezinye izinkambu. Ngenxa yokwakheka kwayo okuyingqayizivele, inezindawo ezinhle ze-foam fluidity, futhi ifaneleka ukwakhiwa kwemikhiqizo enezidingo eziqinile ze-fluidity yesisombululo sesitoko esinegwebu.
