Ngokuthuthukiswa kokuqwashisa ngokuvikelwa kwemvelo kuwo wonke amazwe emhlabeni, imithetho nezimiso zokuvikela imvelo ziyathuthukiswa kancane kancane, ikakhulukazi izidingo zenhlanzeko zemikhiqizo yepulasitiki efana nemithi, ukucubungula ukudla, izidingo zansuku zonke, namapulasitiki amathoyizi. Izinzinzisi zikasawoti omthofu ne-cadmium zizogcina sezithathelwe indawo ngokuphelele iziqinisi ze-PVC ezingenabo ubuthi. . Ukukhiqizwa kwezithasiselo zepulasitiki zangaphandle kuzovame ukuba okukhulu futhi okukhethekile, izidingo zokuvikela imvelo zibaluleke kakhulu, futhi zisebenza kahle futhi zinemisebenzi eminingi. Ucwaningo nokuthuthukiswa kwezinzinzisi ezintsha ze-PVC ezilungele imvelo nezingenabo ubuthi sekuyinkambo engenakugwenywa. Isiqondiso esingenabuthi sezinzile zokushisa ze-PVC sigxile kakhulu ezicini ezimbili ze-organotin ne-calcium-zinc composite heat stabilizers, futhi inqubekelaphambili enkulu yenziwe kukho kokubili. Ibonakala ngokuyinhloko ocwaningweni oluyimpumelelo nasekusetshenzisweni okubanzi kwezinzinzisi zokushisa ze-organotin ezimelelwe yi-United States, kanye nokuthandwa nokusetshenziswa kwezinzinzisi zokushisa eziyinhlanganisela ye-calcium-zinc ezingenabuthi ezimelelwe iYurophu, kodwa intengo ye-organotin ibiza kakhulu. I-calcium-zinc composite stabilizer ekugcineni izokwakha uhlelo lokuzinzisa lwe-PVC lwesikhathi esizayo olungenabuthi kuwo wonke amazwe emhlabeni.
Isetshenziswa kumapayipi, amaphrofayili, ukufakwa kwamapayipi, amapuleti, ukubumba umjovo, ifilimu yokubumba igalelo, impahla yekhebula neminye imikhiqizo yepulasitiki;

1. Isiqiniseko sokuvikela imvelo sangempela;
2. Ukuzinza okuhle kakhulu kwe-thermal;
3. Nikeza isigcwalisi i-dispersibility enhle futhi uthuthukise izakhiwo zemishini yomkhiqizo;
4. Yehlisa ukuguga kwemishini futhi welule isikhathi sokusebenza kwemishini;
5. Ingasetshenziselwa imikhiqizo esobala futhi inikeza imikhiqizo ukungena kahle.
