Uruhu rwa PU n'uruhu rwa PVC byombi ni ibikoresho by'ubukorikori bikunze gukoreshwa nk'ibindi bisimbura uruhu gakondo. Nubwo bisa mu isura, bifite itandukaniro rigaragara mu bijyanye n'imiterere, imikorere, n'ingaruka ku bidukikije.
Uruhu rwa PU rukozwe mu bwoko bwa polyurethane bufatanye n'ikintu gifatanye. Ruroroshye kandi rworoshye kurusha uruhu rwa PVC, kandi rufite imiterere karemano isa n'uruhu nyarwo. Uruhu rwa PU narwo ruhumeka neza kurusha uruhu rwa PVC, bigatuma rworohera kwambara igihe kirekire. Byongeye kandi, uruhu rwa PU rurengera ibidukikije ugereranije n'uruhu rwa PVC kuko rudafite imiti yangiza nka phthalate kandi rurabora.
Ku rundi ruhande, uruhu rwa PVC rukorwa hakoreshejwe gusiga polimeri ya pulasitiki ku gitambaro gikozwe mu mwenda. Rurakomeye kandi ntirushobora kwangirika kurusha uruhu rwa PU, bigatuma rukoreshwa mu gukora ibintu bishobora gufatwa nabi, nk'amasakoshi. Uruhu rwa PVC narwo rurahendutse kandi rworoshye koza, bigatuma rukundwa cyane mu gukoresha mu myambaro. Ariko, uruhu rwa PVC ntiruhumeka nk'uruhu rwa PU kandi rufite imiterere idakwiye ku buryo rushobora kudasa n'uruhu nyarwo.
Muri make, nubwo uruhu rwa PU rworoshye, ruhumeka neza, kandi rukaba rudahungabanya ibidukikije, uruhu rwa PVC rworoshye kandi rworoshye gusukura. Mu guhitamo hagati y’ibikoresho byombi, ni ngombwa kuzirikana ikoreshwa n’imikorere y’umusaruro wa nyuma, ndetse n’ingaruka zishobora kugira ku bidukikije.
