Applications Packaging Storage & Handling
• Neutralizer/alkalinity control (water, flue gas desulfurization).
• Rubber & plastics filler, flame retardancy synergy (with ATH/MDH).
• Agriculture (feed & soil Mg source), sugar refining, ceramics & glass.
• Refractory bricks (DBM), cement & construction.
• 25 kg PP bags with liner • 500–1000 kg FIBCs • Bulk. • Hygroscopic; store dry and sealed. Avoid acid contact; reacts to form salts and heat. Use dust control and PPE; review SDS before handling.
Specs are representative; we tune fineness, reactivity and impurity profile per application (feed, rubber, environmental, refractory). Samples available.
