fa'amautu vevela (PVC) ma isi polymers o lo'o iai chlorine. Methyl tin stabilizer o se polymer maualuga amorphous. Ona o le fausaga faʻapitoa o le PVC, o le a mautinoa lava le faʻaleagaina i le vevela o le gaosiga, faʻapogisaina le lanu, faʻaitiitia ai mea faʻaletino ma masini, ma e oʻo lava i le faʻaaogaina o le aoga. E fa'atumauina le vevela ma gaosia e foia ai lenei fa'afitauli. E tusa ai ma fausaga vailaʻau eseese, faʻamautu vevela e masani ona vaevaeina i masima taʻitaʻia, fasimoli uʻamea, apa faʻalaʻau, eleele e le masani ai, antimony faʻalaʻau ma mea faʻapipiʻi fesoasoani. O ituaiga eseese o oloa e iai a latou lava faʻatinoga faʻatinoga ma e fetaui mo matāʻupu eseese. I tausaga talu ai nei, o le PVC alamanuia ua atiina ae vave, lea na taitai atu ai i le atinae vave o le alamanuia stabilizer vevela. I le tasi itu, o le aʻoaʻoga o le faʻamautuina o le vevela o loʻo faʻateleina ma sili atu ona atoatoa, lea e maua ai tulaga mo le mauaina o oloa PVC sili atu; i le isi itu, o oloa fou talafeagai mo fanua eseese o loʻo faʻaauau pea ona atiaʻe, aemaise lava ona o le oona o masima taʻitaʻi ma uʻamea mamafa. O le mafuaʻaga ona o pisinisi gaosi PVC e muamua filifilia ni faʻamautu vevela e le oona.
I le gaosiga o pisinisi gaosi PVC, e faaopoopo atu i le manaʻomia o le vevela e faʻafeiloaʻi ai le faʻamautuina o le vevela, e masani ona manaʻomia le lelei o le faʻagasologa, faʻafefe o le tau, lanu muamua, faʻamalama malamalama, ma manaʻoga mamafa mo lo latou manogi ma le viscosity. I le taimi lava e tasi, o loʻo i ai le tele o ituaiga o oloa PVC, e aofia ai laupepa, paipa, faʻamatalaga, faʻafefe moldings, tui tui, oloa foam, faʻapipiʻi resins, ma isi. pisinisi lava latou. O le mea lea, o le filifilia o faʻamautu vevela i le taimi o le gaosiga o le PVC e taua tele. Organotin heat stabilizers o faʻamautu vevela na maua i le taimi nei
