Njengempahla eguquguqukayo, ulusu oluyilwe yi-PU lusetyenziswe kumashishini ahlukeneyo, kuquka imfashini, iimoto, kunye nefenitshala. Kwiminyaka yakutshanje, luye lwathandwa kakhulu kushishino lwefenitshala ngenxa yeenzuzo zalo ezininzi.
Okokuqala, ulusu oluyilwe yi-PU luhlala ixesha elide olunokumelana nokuguguleka nokonakala ngenxa yokusetyenziswa rhoqo. Ngokungafaniyo nolusu lokwenyani, aluphuhli imibimbi kunye nemibimbi ngokuhamba kwexesha. Le nto iyakwazi ukumelana namabala kunye nokunyamalala, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo lwempahla yokuhombisa edinga ukumelana neemeko ezahlukeneyo zokusingqongileyo.
Okwesibini, isikhumba esenziwe nge-PU siyindlela enobuhlobo nokusingqongileyo endaweni yesikhumba sokwenyani. Njengoko sidalwa ngenkqubo eyenziwe ngumntu, iityhefu ezimbalwa zikhutshwa kwindalo ngexesha lokwenziwa. Ukongeza, ukusebenzisa isikhumba esenziwe nge-PU kubonelela ngesisombululo esizinzileyo sokunciphisa inkunkuma kuba senziwe ngezinto ezenziwe nge-PU endaweni yezikhumba zezilwanyana.
Okwesithathu, ulusu oluyilwe nge-PU lufumaneka kwiindidi ezahlukeneyo zemibala kunye neepateni kunelusu lokwenyani. Oku kuvula amathuba amaninzi oyilo kubavelisi befenitshala kunye nabathengisi, okwenza kube lula ukufanisa izitayile ezithile zangaphakathi okanye ukwenza ngokwezifiso iziqwenga zefenitshala.
Okwesine, ulusu oluyilwe nge-PU lufikeleleka lula kunelusu lokwenyani. Ngenxa yeendleko eziphantsi zokuvelisa, lunokuba nexabiso eliphantsi kunelusu lokwenyani ngelixa lubonelela ngeenzuzo ezininzi ezifanayo. Oku kwenza ukuba lube lukhetho olunomtsalane kubathengi abakwibhajethi encinci.
Okokugqibela, ulusu oluyilwe nge-PU kulula ukulucoca nokuyilungisa. Lufuna nje ukusula ngelaphu elimanzi ukususa nayiphi na into echithekileyo okanye inkunkuma, nto leyo eyenza ukuba lube lolona khetho lufanelekileyo kumakhaya axakekileyo anabantwana abancinci okanye izilwanyana zasekhaya.
Lilonke, iingenelo zokusebenzisa ulusu oluyi-PU kwimveliso yefenitshala zininzi kakhulu. Ukususela ekuqineni ukuya ekufikeleleni, iye yaba yinkwenkwezi ekhulayo kushishino, ibonelela ngesisombululo esinobuhlobo nokusingqongileyo nesihlala ixesha elide sefenitshala esikwabonelela ngokuguquguquka ngakumbi koyilo.
Ukuqukumbela, ulusu oluyilwe nge-PU lukhetho oluhle kakhulu kubavelisi befenitshala kunye nabathengi ngokufanayo. Ukuguquguquka kwalo kunye nozinzo lwalo kwenza ukuba lube yinto engcono kakhulu yokufakelwa ifanitshala, nto leyo enegalelo kushishino lwefenitshala olunobuhlobo nokusingqongileyo kunye nolwenziwe ngokwezifiso.
