FireGuard Halogen-Free Flame Retardant BS-FR200
Eco-friendly halogen-free flame retardant additive for engineering plastics and cable compounds.
Product Details
What is FireGuard BS-FR200?
FireGuard BS-FR200 is a next-generation halogen-free flame retardant additive engineered for high-performance thermoplastics. It delivers UL94 V0 rating at typical loading levels of 20–30 %, enabling manufacturers of PA, PBT, PC, and cable compounds to meet stringent fire-safety standards without relying on brominated or chlorinated chemistries.
Why choose a halogen-free solution?
Traditional halogenated flame retardants release toxic and corrosive gases during combustion. BS-FR200 uses an intumescent phosphorus-nitrogen synergy that forms a protective char layer, drastically reducing peak heat release rate and smoke density. The result is low-smoke, zero-toxicity fire protection that complies with RoHS, REACH, and IEC 61249-2-21 halogen-free definitions.
Which polymers and applications is it suited for?
BS-FR200 has been validated across a broad range of engineering resins including PA6, PA66, PBT, PET, PC, and PC/ABS blends. Typical end-use sectors include electrical connectors, circuit-breaker housings, wire-and-cable jacketing, EV battery module components, and consumer-electronics enclosures where both flame performance and environmental compliance are non-negotiable.
How does it affect mechanical properties?
One of the key advantages of BS-FR200 is its minimal impact on base resin mechanics. At the recommended 25 % loading in glass-filled PA66, tensile strength retention exceeds 85 % and notched Izod impact strength stays above 70 % of the unfilled, unretarded baseline. This balance allows designers to achieve V0 without over-engineering wall thickness or sacrificing drop-test reliability.
What processing considerations should be noted?
BS-FR200 is supplied as a free-flowing powder with a decomposition onset above 320 °C, making it compatible with standard twin-screw compounding and injection-molding cycles. Pre-drying the additive at 80 °C for 2 hours before extrusion minimizes moisture-induced hydrolysis in polyamide systems. No special screw geometry or wear-resistant barrel upgrades are required.
What certifications and packaging options are available?
The product carries SGS test reports confirming UL94 V0 at 1.2 mm (for select formulations), UL White & Yellow recognition pending, and full RoHS 2.0 / REACH SVHC compliance. It ships in 20 kg multi-wall paper bags with PE liner or 500 kg bulk jumbo bags, with a shelf life of 24 months when stored below 40 °C in a dry, ventilated warehouse.
