Vinthu vyakupangika na khebo vya kuwaro vikugaŵika chomene mu misasa yiŵiri: polyethylene (PE) na polyvinyl chloride (PVC).
Polyethylene (PE) : Likulongora kukhora kwapachanya, kuvwara vyakuvwara, kukana kukhwaŵa, na kukana chomene. Kweniso ili na vinthu viwemi vya magesi na kupanga vinthu. Ntheura, para makhebo ghakuwonekera pa mlengalenga, nga ni mu tunnel panji Bridges uko kukukhumbikwa kuti moto uŵepo, tikuyowoya kuti mugwiriskirenge nchito makhebo gha polyvinyl gha chloride sheathed.
Polyvinyl chrodelo (PVC) : Chidumbirano ichi chili na vinthu vyakujifumiska -} vyakufumiska, nkhongono yiwemi chomene ya moto, mtengo wakuchepa na kusinthasintha kuwemi. Ntheura, para makhebo ghakuŵikika mu vigaŵa vyakuzizima, ghakubisika mwachindunji pasi pa charu, ghakuzura na mchenga mu migelo ya khebo, panji para maji gha pasi pa charu chapasi ghali pachanya ndipo nyengo zose ŵakubizgika, tikuyowoya kuti musankhe nthambo za polyethylene za sheathed!
