Product Overview
FR 8255 is a high-efficiency composite flame retardant, formulated as a synergistic blend of antimony trioxide and zinc borate. The two components exhibit excellent synergistic effects, which can significantly cut formulation costs while maintaining comparable flame-retardant performance. FR 8255 is widely applicable to a broad range of polymer materials, including PP, PE, PS, ABS resins, and various rubbers. It can also be compounded with other flame retardants such as aluminum hydroxide, and brominated flame retardants (e.g., DBDPE, BDDP) to enhance overall fire resistance. At a recommended dosage of 5% – 10%, this product enables the treated materials to meet the V-0 Flame-Retardant Rating standard. |

Frequently Asked Questions
Q
What is FR 8255 and what makes it a composite flame retardant?
FR 8255 is a composite flame retardant consisting of a 50:50 synergistic blend of antimony trioxide and zinc borate. The combination of these two components creates a powerful synergistic effect, delivering high flame-retardant efficiency while helping to reduce overall formulation costs compared to using either component alone.
Q
Which polymer materials is FR 8255 compatible with?
FR 8255 is suitable for a wide range of polymer materials, including polypropylene (PP), polyethylene (PE), polystyrene (PS), ABS resins, and various rubber compounds. Its versatility makes it an ideal choice for manufacturers working across multiple material types.
Q
Can FR 8255 be used together with other flame retardants?
Yes. FR 8255 can be effectively compounded with other flame retardants such as aluminum hydroxide (ATH) and brominated flame retardants including DBDPE and BDDP. These combinations further enhance the overall fire resistance of the final product.
Q
What flame-retardant rating can be achieved using FR 8255?
At a recommended dosage of 5% to 10%, FR 8255 enables treated materials to achieve the UL 94 V-0 flame-retardant rating, which is one of the highest standards for flame retardancy in plastic materials.
Q
What are the physical specifications of FR 8255?
FR 8255 is a white powder with a median particle size (D50) of 1–3 μm and a surface moisture content of less than 0.5%. These properties ensure consistent dispersion and processing performance in various polymer systems.
Q
What packaging options are available for FR 8255?
FR 8255 is available in three standard packaging options to meet different procurement needs: 25 kg/bag for smaller orders or laboratory use, 500 kg/bag for medium-scale production, and 1000 kg/bag for bulk industrial applications.
