3M™ Flame Retardant Additive is an additive for polycarbonate which can be used effectively at low usage levels. This non-brominated, non-chlorinated additive is formulated to produce optically-clear, haze-free grades of polycarbonate for extrusion and moulding.
Chemically and thermally stable up to 450°C, 3M™ Flame Retardant Additive, is often used synergistically with fibrillating PTFE (Polytetrafluoroethylene) to achieve V-0 in UL 94 rating. This material has also been found to be effective as a flame retardant without the use of synergists. For most effective incorporation, it is recommended that the additive be initially dispersed into a 10% or more masterbatch and then compounded into the final plastic blend.
