Abstract.
Since polyvinyl chloride (PVC materials) is easily flammable, it is added to different chemical compounds, as a fire retardant, which make it resistant to the effects of fire. Fire retardants frequently used in the production of PVC materials today include zinc stannate, zinc hydroxystannate and antimony (III) oxide. Although antimony (III) oxide shows the best properties as a fire retardant PVC material, this work points to its high toxicity, offering a reason why it should not be used.
Key Words:
polyvinyl chloride, fire retardant, toxicity
PROTIVPOŽARNI PVC MATERIJALI
S obzirom na to da je polivinil hlorid (PVC materijal) lako zapaljiv, dodaje se različitim hemijskim jedinjenjima koja zatim imaju dejstvo protivpožarnog materijala i čine ga otpornim na uticaj vatre. U protivpožarni materijal koji se često koristi u proizvodnji PVC materijala spadaju cink stanat, cink hidroksistanat i antimon (III) oksid. Iako antimon (III) oksid ima najbolje odlike kao protivpožarni PVC materijal, u ovom radu ukazuje se na njegov visok nivo toksičnosti, pa se iz tog razloga ne bi trebalo koristi.
Ključne reči: polivinil hlorid, protivpožarni materijal, toksičnost
