  • Magnesium Hydroxide For Aluminum Composite Panel - China

    price: 100.00 Dollar US$

    Description The halogen free flame retardant aluminum composite panel made from our magnesium hydroxide is accredited by UL94-V-0, UBC 26-9, BS 476, DIN 4102 Class B1, and ASTM E 119.

    And MDH (Magnesium Hydroxide) price is more competitive than ATH (Aluminum Hydroxide) price.

    MDH is better than ATH as halogen free flame retardant in the following point: 1 - MDH and ATH are similar when heated.

    They both create water and metal oxide.

    Water absorbs heat, and metal oxide covers the surface.

    But MgO absorb more acid.

    2 - Magnesium hydroxide (MDH) degrades at 330℃, 100℃ higher than Aluminum Hydroxide (ATH) does, so MDH is better for plastics needing high temperatures.

    3 - MDH dissociation energy is 1.37kJ/g; ATH dissociation energy is 1.17KJ/g; and thermal capacity of MDH is 17% higher than ATH also.

    So MDH have higher flame retardant efficiency.

    4 - Magnesium hydroxide with more carbonization can reduce more smoke.

    5 - MDH particle is softer than ATH, so less abration will happen during compounding process.

    It’s good for compounding machine.

    Commercial name: Brucite Key component: Mg(OH)2

    Application: Halogen free flame retardant

    Strong point: Non-toxic, High efficient, Smoke suppression, Environmental.

    Flame-retardant Mechanism of Magnesium Hydroxide Halogen Free Flame Retardant 1 - Decomposition of magnesium hydroxide absorbs heat, which is beneficial to reduce the flame combustion temperature.

    2 - The decomposition of magnesium hydroxide create water, it’s not only the coolant, also reduce the smoke density as thinner.

    3 - The decomposition of magnesium hydroxide creates MgO, which is featured with big specific surface.

    So it is easy to absorb smoke and cover the combustible material.
