    Application

    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.

    ⚠ Recommended Dosage: 5% – 10%   Enables treated materials to meet the V-0 flame-retardant rating standard.

    Package 25 kg/bag 500 kg/bag 1000 kg/bag
    Frequently Asked Questions
    Q
    What is FR 8255 and what does it consist of?
    FR 8255 is a high-efficiency composite flame retardant composed of a 50:50 synergistic blend of antimony trioxide and zinc borate. It is supplied as a white powder and is designed to deliver strong flame-retardant performance while helping to reduce overall formulation costs.
    Q
    Which polymer materials is FR 8255 compatible with?
    FR 8255 is compatible with a wide range of polymer materials, including polypropylene (PP), polyethylene (PE), polystyrene (PS), ABS resins, and various rubber compounds, making it highly versatile for different industrial applications.
    Q
    Can FR 8255 be combined with other flame retardants?
    Yes. FR 8255 can be effectively compounded with other flame retardants, including aluminum hydroxide and brominated flame retardants such as DBDPE and BDDP, to further enhance the overall fire resistance of the final material.
    Q
    What flame-retardant rating can FR 8255 help achieve?
    At a recommended dosage of 5% to 10%, FR 8255 enables treated materials to meet the UL94 V-0 flame-retardant rating standard, which represents the highest level of flame resistance in the UL94 vertical burn test classification.
    Q
    What are the key physical specifications of FR 8255?
    FR 8255 has a median particle size (D50) of 1–3 μm and a surface moisture content of less than 0.5%. These properties ensure consistent dispersion within polymer matrices and reliable processing performance.
    Q
    What packaging options are available for FR 8255?
    FR 8255 is available in three standard packaging sizes: 25 kg/bag, 500 kg/bag, and 1000 kg/bag, offering flexibility for both small-scale trials and large-volume industrial production requirements.
