Magnesium Hydroxide

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.

Specification of Magnesium Hydroxide :
Mg(OH)2	>=97%
H2O+	31%
CaO	0.5% Max.
MnO	0.01% Max
CuO	0.006% Max
Fe2O3	0.3% Max
Whiteness	93% min.
Average Particle size (Microns)	varies as per grade from 1 - 45 microns
Organic Coating	<=3%
Ph	About 9.5
Moisture	0.5% max
Density	2.3

Advantage:

• 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 specially

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, aluminium composite panel compound, etc.
