Cel-Span® F R 739 contains a superior non-halogen flame retardant concentrate system for transparent, polycarbonate compounds. Cel-Span® F R 739 concentrate, when diluted in the recommended levels, meets Underwriters’ Laboratories (UL)94V0 flame retardant requirements up to 1/32 thin sections. For thin sections, in addition to Cel-Span® F R 739, we recommend Cel-Span® F R 739 at 7-8% levels to achieve the UL 94V0 requirement.
Application:Cel-Span® F R 739 is a diluted concentrate of a unique potassium salt and does not affect the transparency of polycarbonate resin since the additive has the same refractive index as the resin. Cel-Span® F R 739 is used for electronic markets,military, and aircraft applications, where clarity and flame retardants are requirements. Since Cel-Span® F R 739 is used at low levels the cost to produce a flame retardant PC is minimal.
Toxicity Safety:No adverse health effects from Cel-Span® F R 739 are known. All the additives in Cel-Span® F R 739 are GRAS and TSCA listed.
Packaging and Storage:Cel-Span® F R 739 is packaged in 110 pound fiber drums with aluminum liners. We recommend that this product be kept closed in a dry location for functional use and ease of handling. Compliance to these recommendations will mean no further need for drying the concentrate prior to molding.
