Bulab® Flamebloc 428 (calcium metaborate) is a fire retardant and smoke suppressant for use in plastics, paints, textiles, and rubber compounds. It contains no lead, barium, zinc, or other regulated heavy metals. Since it is borate based, Bulab® Flamebloc 428 will provide char formation and subsequent smoke suppression. This fine particle size material is easily incorporated into a formulation with maximum dispersibility.
Bulab® Flamebloc 428 is recommended for applications with stringent smoke requirements. The product performs best when used as a synergist with halogen-containing compounds. In many applications, Bulab® Flamebloc 428 can be used as a partial replacement for antimony-based compounds.
