Rectivas supplies flame retardant polycarbonate additives and masterbatch for PC and PC/ABS compounds. Compare halogen-free, phosphorus-based, sulfonate salt, silicone, additive and masterbatch options for UL94 V-0, transparency, heat resistance and engineering plastic housings.
Fig. PC01 — PC flame retardant proofUse a real image of PC pellets, transparent plaques, molded engineering parts, UL94 bars and heat-aging notes. The image should prove this page is specific to polycarbonate, not a generic plastics page.
Flame retardant polycarbonate selection is different from general plastic selection. Polycarbonate and PC/ABS buyers often need UL94 V-0 at a defined thickness while protecting transparency, light color, heat resistance, hydrolysis stability, impact strength and molding flow.
Use powder or blended flame retardant additives when you control PC compounding recipes, active loading, transparency, heat resistance and mechanical balance internally.
Use PC flame retardant masterbatch when cleaner dosing, pre-dispersion and simpler trial handling are more important than direct powder feeding.
Use halogen-free PC flame retardant directions when electronics, lighting or export buyers require non-halogenated chemistry, RoHS, REACH or restricted substance support.

For PC, the form decision depends on whether the buyer controls compounding or needs a production-friendly pellet concentrate. PC compounders often prefer additives, while molders may prefer PC flame retardant masterbatch for clean trials and simpler dosing.
You need direct formulation control, active loading adjustment, clarity tuning or integration into an existing PC compounding recipe.
You need cleaner dosing, easier handling, better pre-dispersion and direct let-down on PC injection molding or extrusion lines.
PC flame retardant projects often prefer halogen-free systems because polycarbonate is used in electronics, lighting, appliances and engineering housings. The correct system should still be validated for UL94 thickness, transparency, heat aging, impact strength and processing stability.
Common for engineering plastic applications where RoHS, REACH, non-halogenated chemistry and restricted substance lists matter.
Often considered for halogen-free PC, but transparency, heat aging, hydrolysis resistance, color and impact strength must be validated.
PC/ABS compounds need a formulation direction adjusted to the PC/ABS ratio, target thickness, impact requirement and surface quality. Brominated systems are still used in opaque PC/ABS housings.
View brominated flame retardant options →Most PC projects need a balance of flame rating, transparency or color, heat resistance, hydrolysis stability, impact strength and total cost.
A useful PC recommendation requires more than the word polycarbonate. Grade, PC/ABS ratio, part thickness, target UL94 rating, transparency, color, heat resistance, hydrolysis stability, molding method and compliance needs all affect additive choice and loading level.

PC and polycarbonate flame retardant systems may use phosphorus-based, sulfonate salt, silicone, halogen-free or compounded additive packages depending on UL94 target, transparency, color, heat resistance, impact strength and compliance needs.
PC compounders often choose additives for formulation control, while molders and converters may choose PC flame retardant masterbatch for cleaner dosing, pre-dispersion and easier production trials.
Yes. Halogen-free PC flame retardant systems are common for engineering plastic applications, but transparency, color, hydrolysis resistance, heat aging, impact strength and UL94 thickness must be validated.
