Martin Marietta Magnesia Specialties’ high purity magnesium oxide products combine low reactivity, high quality, consistency, and fine particle size for use as a processing aid in the production of liquid crystal display (LCD) substrate found in smartphones, tablets, televisions, and computer monitors.

For fiberglass applications, melt viscosity must be fairly high so that the semi-molten strands have integrity thus preventing breakage as the glass emerges from the spinnerets. Because of its properties, MagChem® magnesium oxide raises the viscosity of the glass melt ensuring a more precise mold. Fiberglass is used primarily in FRP (fiberglass reinforced plastic) products such as bathroom showers, tubs and windmill blades.
