Industrial: Flame Retardancy (NikoMag A5)

Thermal Stability: Withstands temperatures up to 330°C, outperforming Aluminium Trihydrate (ATH) and allowing for the processing of high-temperature engineering plastics Smoke Suppression: As it decomposes, it reduces the smoke density of burning polymers, a critical safety requirement for public transport and construction materials Polymer Compatibility: Hexagonal crystal structure of the A5 grade ensures excellent dispersion in PP, PE, and EVA matrices.

Pharmaceutical: API & Excipient (IP/BP/USP)

Antacid Action: Neutralizes gastric acid to form magnesium chloride and water, providing rapid relief from hyperacidity without systemic alkalosis Osmotic Laxative: At higher doses, it remains unabsorbed in the bowel, drawing water in through osmosis to soften stools Mineral Supplementation: Used as a safe source of magnesium in dietary supplements.

Specialized Nutrition & Cosmetics

Food Additive (E528): Acts as an acidity regulator and color stabilizer in processed foods Personal Care: Used in deodorants (as an odor absorber) and mineral makeup for its oil- absorbing properties

Temperature

15°C – 25°C, Store in a cool, dry place away from direct sunlight.

Environment

Keep away from acids and incompatible materials.

Protection

Ensure containers are tightly sealed to prevent moisture absorption.
