Ucingo lokwenziwa, uthango lwepulasitiki noma ucingo lwevinyl noma lwe-PVC wuthango olwenziwa kusetshenziswa amapulasitiki okwenziwa, njenge-vinyl, i-polypropylene, inayiloni, i-polythene ASA, noma evela kumapulasitiki ahlukahlukene agaywe kabusha.Inhlanganisela yamapulasitiki amabili noma ngaphezulu angasetshenziswa futhi ukukhulisa amandla kanye nokuzinza kwe-UV kocingo.Uthango lokwenziwa lwaqala ukwethulwa embonini yezolimo ngeminyaka yawo-1980s njengesixazululo esibiza kancane/esiqinile sokubiyela amahhashi isikhathi eside.Manje, uthango lokwenziwa lusetshenziselwa uthango lwezolimo, ujantshi womjaho wamahhashi, kanye nokusetshenziswa kwezindawo zokuhlala.Uthango lwe-synthetic ngokuvamile lutholakala lufakwe ngaphambili, ngezitayela ezihlukahlukene.Ivamise ukuba lula ukuyihlanza, imelana nesimo sezulu futhi inezidingo zokunakekelwa okuphansi.Kodwa-ke, kungase kubize kakhulu kunezinto ezifaniswayo, futhi imikhiqizo eshibhile ingaba ngaphansi kokuqina kunezinto zocingo ezivamile.Ezinye izinhlobo zingase zibe brittle, zifiphele noma zehlise izinga ngemva kokuchayeka isikhathi eside ezimeni ezishisayo kakhulu noma ezibandayo.Muva nje, i-titanium dioxide nezinye iziqinisi ze-UV ziye zafakazela ukuthi ziyizithasiselo ezinenzuzo enqubweni yokukhiqiza i-vinyl.Lokhu kuye kwathuthukisa kakhulu ukuqina kwe-vinyl ngokunikeza isivikelo se-UV esibalulekile emisebeni eyingozi yelanga, ukuvimbela ukuguga ngaphambi kwesikhathi nokuqhekeka komkhiqizo, okuwenza uhlale isikhathi eside kunezinye izinto ezifana nokhuni.
