Grupo Industrial C&C Antimony Trioxide

Grupo Industrial C&C Antimony Trioxide is a high purity fine white powder flame retardant agent which inhibits free radicals that are responsible for combustion expansion. By synergic effect, its activity is strongly incremented in halogen presence and that is the reason of its exclusive participation in PVC compounds for non-combustible elements’ manufacturing.
