Imathiriyeli ekrwada yetyhubhu yenayiloni yipolyamide (eyaziwa ngokuba yinayiloni).I-tube ye-nylon ineempawu zokumelana nokushisa okuphezulu kunye nokuphantsi, ubunzima bokukhanya, ukunyanzeliswa kwe-corrosion, ukunyanzeliswa kwengcinezelo ephezulu, njl.Ityhubhu yenayiloni iya kuba yinto efanelekileyo yokutshintsha iityhubhu zentsimbi.

Umbhobho we-PU unokuguquguquka okungcono kunye nokumelana noxinzelelo oluphezulu.Ngoku isetyenziselwa ukubonelela ngamanzi kunye nokukhupha amanzi.Umbhobho wegesi kulula ukudibanisa kwaye unokudibaniswa ne-hot melt welding.Amandla onxibelelwano angcono kunamandla alo.Umbhobho we-PU owenziwe ngezinto ezintsha ziselubala kwaye azikho inetyhefu.Ingasetyenziswa njengombhobho wokubonelela ngamanzi kwaye inokugotywa.Ngokuqhelekileyo isetyenziswa kwiiprojekthi zamanzi okusela ezilalini, ukunkcenkceshela okonga amanzi kunye nezinye iiprojekthi.
