Description:
PAKMAG is a high-purity caustic calcined natural magnesium oxide with a controlled moderate activity. Our product has a very low content of iron and heavy metals. The low level of impurities makes this product suitable for different applications such as:
- Cellulose
- Fertilizer
- Animal feed
- Pulp and paper
- Glass industry
- Rubber industry
- Hydrometallurgy
- Pharma
- Magnesium is an essential nutrient in all animals and has many important functions in the body for normal appetite, production, and reproduction.
- Magnesium oxide is one of the functional materials with high activity, light weight, and loose structure, widely used in flame retardants and medicine.
- Magnesium oxide is odorless, tasteless, and non-toxic. It is soluble in acids and ammonium salts but insoluble in water and ethanol.
- Magnesium oxide has pressure resistance characteristics.
- Storage: Store in a dry and well-ventilated area.
- Packaging: Big Bags or Small Bags with water-resistant material.
- Shelf-life: Two years under suitable storage conditions.
