0.0002 Versatile Applications Across Industries Pharmaceutical Industry

• Formulation of ointments, laxatives, analgesics, and antidotes.

• Key intermediate for manufacturing anticonvulsants, antibiotics, and other pharmaceutical APIs (Active Pharmaceutical Ingredients).

• Complies with USP/BP/EP standards, ensuring safety for medical use.

Microbial & Fermentation Industry

• Essential component in microbial culture media (supports cell growth and metabolism).

• Brewing additive: Supplements magnesium to enhance yeast activity and beer flavor (ideal for "Burton" style beer production).

• Nutrient source for industrial fermentation processes (e.g., enzyme production, biofuel synthesis).

Food & Light Industry

• Food additive: Acts as a nutrient supplement (magnesium source), firming agent (for fruits/vegetables), and flavor enhancer.

• Production of fresh yeast, monosodium glutamate (MSG), functional beverages, and mineral water.

• Raw material for health salts, bath crystals, and stabilizer for dicalcium phosphate in toothpaste.

Chemical Industry

• Primary raw material for synthesizing magnesium-based compounds (magnesium stearate, magnesium hydrogen phosphate, magnesium oxide) and sulfate derivatives (potassium sulfate, sodium sulfate).

• Enables high-purity output for downstream chemical manufacturing.

Textile, Dyeing & Leather Industry

• Textile: Alkali-resisting agent, weighting agent for fine cotton/silk, and filler for kapok products.

• Key material in rayon production.

• Leather: Filler to improve heat resistance and durability of finished leather goods.

Electroplating & Fire Retardant Sector

• Electroplating: Conductive salt that enhances conductivity and surface smoothness of nickel plating baths; additive for aluminum coloring processes.

• Fire retardant: Effective in acrylate resins, epoxy resins, unsaturated polyester, and polyurethane plastics (reduces flame spread and smoke emission).

Agriculture & Animal Husbandry

• Agriculture: High-efficiency fertilizer supplying magnesium and sulfur (essential medium elements for crops).

Promotes chlorophyll formation and photosynthesis, boosting crop yield and fruit quality (suitable for vegetables, fruits, and cash crops).

• Animal husbandry: Nutritious feed additive to prevent magnesium deficiency in livestock and poultry.

Construction & Other Industries

• Construction: Coagulant to regulate cement setting time and improve concrete performance.

• Additional uses: Raw material in explosives, matches, ceramics, glass, pigments, paper pulp, and ABS resin production.

Packaging & Storage

We offer flexible packaging solutions to meet your logistics and inventory needs, while ensuring product stability:

• Packaging Options: 25kg/bag (kraft paper with PE liner), 50kg/bag (PP woven bag), or custom packaging (e.g., 1-ton big bags) as per your requirements.

• Storage Conditions: Store in a cool, dry, and well-ventilated warehouse.

Keep away from moisture, direct sunlight, and incompatible substances (e.g., strong acids/bases) to prevent caking or quality degradation.

• Shelf Life: 24 months under proper storage conditions.
