Physical and chemical indicators:
Product Name Whiteness Temperature Â°C Specific Gravity (g/cm3) pH Synergistic Flame Retardant FRP-33 90 400 2.6 7.0-7.5
Chemical composition Al Si Magnesium activator Other flame retardant mechanisms:
(a) Gas-phase flame retardant mechanism: The metal oxides and halogen-based flame retardants in this product act to increase the dehydrohalogenation reaction and release a more effective flame inhibitor, the metal halide. Microscopic examination revealed that the metal compounds in this material changed the appearance of charcoal, making it bright and crack-free. These changes will enable the carbon layer to have better insulation and thus improve flame retardancy.
(II) Condensation phase flame-retardant mechanism: When the material added with this product is heated, its structural hydrated layer hydroxyl and interlayer ions are eluted in the form of water and CO2, which reduces the concentration of combustion gas and blocks the flame retardant effect of O2. . In the process of flame retardant, the heat absorption is large, which is beneficial to reduce the high temperature generated during combustion. A large number of experiments and applications prove that: This product and bromine antimony mixed flame retardant effect is better than a simple bromine antimony flame retardant, mechanical properties improve, improve Oxygen index, reducing droplet dripping.
This product is mainly used in modified engineering plastics such as PA, PBT, PET, PP, PE, ABS, PS and other bromine antimony system flame retardant copolymers, can partially replace antimony trioxide, play synergistic flame retardant, reduce costs , smoke suppression, reduce toxicity, reduce the role of proportion. This product is easy to use and can be applied to a variety of plastics. It can be used as a synergistic flame retardant in bromine oxime and halogen-free flame retardant systems.
