Niknam Chemicals Magnesium Hydroxide

Niknam Chemicals Magnesium Hydroxide is a white powder with specific gravity of 2.36. , very slightly soluble in water; decomposing at 350°C. Magnesium Hydroxide is an inert filler, flame retardant and smoke suppressant for plastics,synthetic rubber, reinforced polyesters, phenolics and urethane foam.Magnesium hydroxide releases its 31% water when heated to above 325°C, Which cools the product below flash point to reduce fire occurrence. Medicinally it, in the form of a mixture (milk of magnesia), is also used as an antacid and as a osmotic laxative.

Functions: Flame Retardant, Smoke Suppressant

Chemical Family: Magnesium & Magnesium Compounds

Compatible Polymers & Resins: Ethylene Propylene Diene Monomer (EPDM), Ethylene Vinyl Acetate (EVA), Polyethylenes (PE), Polypropylenes (PP), Polyvinyl Chloride (PVC)

    Materials Features
    Advantages
    • Initial dehydration temperature is 340°C, suitable for high temperature process of the flame – retardant rubber and plastic
    • The effectiveness of flame – retardant and smoke suppressant is better than Aluminum Hydroxide
    • Magnesium Hydroxide also has strong reinforcement due to high fineness & the surface is coated speciall

    Applications & Uses

    Usage

    Widely used for flame - retardant rubber and plastic products that must be lower halogen, non-halogen, low-smoking. Also can be used in thermoplastic and elastomers such as EVA, EPDM, PVC, PE, PP resins, aluminum composite panel compound, etc
