Flame retardancy is becoming increasingly important
in several applications. Infact the usage of flame retardant (FR)
additives has reached a level of close to one million tonnes, almost
15% of the total
additives that are used in plastics.
Additive suppliers have carried out significant development work
to achieve synergy of different materials to achieve better fire
retardancy at a lower costs or at a lower environmental impact.
Antimony trioxide, a major FR additive has been a combined with
several halogenated additives like solid chlorinated PE, Bromo derivatives
as well as non-halogenated additives like Zinc Borates or Zinc Oxide,
Mineral Sillicates, Magnesium compounds and even Iron compounds.
Synergistic technology thus plays an important role in extracting
best performance.
