Ngokwandiswa kolwazi ngokhuseleko lokusingqongileyo kuwo onke amazwe ehlabathi, imithetho nemigaqo yokhuseleko lokusingqongileyo iyaphuculwa ngokuthe ngcembe, ngakumbi iimfuno zococeko kwiimveliso zeplastiki ezifana namayeza, ukusetyenzwa kokutya, iimfuno zemihla ngemihla, kunye neeplastiki zokudlala. I-lead kunye ne-cadmium stabilizers yetyuwa ekugqibeleni iya kutshintshwa ngokupheleleyo zizinzinzi ze-PVC ezingenayo ityhefu. . Ukuveliswa kwezongezelelo zeplastiki zangaphandle kuya kuthandeka ukuba kukhulu kwaye kukhethekileyo, iimfuno zokukhuselwa kwendalo zixatyiswa kakhulu, kwaye zisebenza kakuhle kwaye zinemisebenzi emininzi. Uphando kunye nophuhliso lwezinzisi zePVC ezitsha ezihambelana nokusingqongileyo nezingeyotyhefu sele ziyinto engenakuthintelwa. Ulwalathiso olungenabutyhefu lwe-PVC ezizinzisi zokushisa lugxininiswe kakhulu kwiinkalo ezimbini ze-organotin kunye ne-calcium-zinc composite heat stabilizers, kwaye inkqubela enkulu yenziwe kuzo zombini. Ibonakaliswa ikakhulu kuphando oluyimpumelelo kunye nokusetyenziswa okubanzi kwe-organotin ukuqina kobushushu obumelwe yi-United States, kunye nokuthandwa kunye nokusetyenziswa kwe-non-toxic calcium-zinc composite heat stabilizers emelwe yiYurophu, kodwa ixabiso le-organotin libiza kakhulu. I-calcium-zinc composite stabilizer ekugqibeleni iya kwakha inkqubo yozinziso ye-PVC yexesha elizayo engeyotyhefu yawo onke amazwe ehlabathi.
Isetyenziswe kwimibhobho, iiprofayili, izifakelo zemibhobho, iipleyiti, ukubumba inaliti, ifilimu yokubumba ifilimu, izinto zentambo kunye nezinye iimveliso zeplastiki;
