Fire retardant PVC compounds

PVC is less flammable that other polymers however the addition of flame retardant additives is still very beneficial.

PVC requires a lower level of flame retardant additives to achieve good fire resistance. When PVC does burn it releases acid gases that are harmful to humans and corrosive to metal. PVC also generates thick black smoke upon burning significantly reducing visibility in a fire situation.

Addition of UltraCarb

A natural halogen free flame retardant, UltraCarb can replace antimony trioxide in PVC compounds; it is less harmful and will still give the improved fire performance required. Another significant benefit of using UltraCarb in PVC is the suppression of smoke that this unique flame retardant mineral provides.

UltraCarb in PVC

Within flexible foams PVC is used to increase the flame retardancy which can be further increased with the addition of UltraCarb.

For PVC cable compounds the formulation is enhanced with the addition of UltraCarb as a flame retardant additive; oxygen near the burning surface is diluted and the evolution of smoke and flammable gases is suppressed. The UltraCarb inhibits the combustion process and propagation through burning droplets as it forms a stable char during decomposition.
