Westco Mag Oxide 140
LIGHT BURNED TECHNICAL GRADE MAGNESIUM OXIDE
CHARACTERISTICS:
DESCRIPTION: Mag Oxide 140 is a high purity technical grade of magnesium oxide processed from magnesium rich brine. This fine powder has a very high reactivity index, low bulk density, and excellent flow properties. USES: Mag Oxide 140 is well suited for many rubber formulations, particularly neoprene. It finds wide use as a filler, anti-caking agent, and pigment extender. Mag Oxide 140 is extremely efficient in chemical processes where ease of conversion is a factor COMPOSITION: Typical Specifications *Magnesium oxide (MgO), % ignited basis 98.2 97.0 min. *Calcium oxide (CaO), % 0.8 1.0 max. *Silica (SiO2),% 0.35 0.5 max. *Iron oxide (Fe2O3), % 0.15 0.3 max. *Aluminum oxide (Al2O3), % 0.10 0.2 max. *Chloride (Cl), %
