It is widely used in electronic semiconductors, pharmaceutical preparations, precision chemicals, high-end flame retardants, and other fields.

Core strengths

1. Ultra pure purity control, with extremely low impurities

-Core purity benchmark: Magnesium hydroxide content ≥ 99.5% (top tier products can reach 99.8%), key impurity content exceeds industry limits - Fe ₂ O3 ≤ 0.005%, CaO ≤ 0.08%, SiO ₂ ≤ 0.03%, heavy metals (Pb/Cd/As) ≤ 1ppm, avoiding interference from impurities on end product performance from the source, suitable for high-end scenarios such as precision manufacturing, medicine and food.

2. Precise and controllable structure and performance

-Narrow distribution particle size design: Customizable D50 particle size range of 0.3-5 μ m, particle size distribution span (D90/D10) ≤ 2.5, excellent dispersibility, can be uniformly integrated into polymer materials, pharmaceutical preparations, coatings and other systems, without the need for additional dispersants to achieve stable dispersion and improve product comprehensive performance.

-High activity crystal structure: Using directional crystallization technology, regular hexagonal plate-like crystals are formed, with a surface hydroxyl (- OH) active site density of ≥ 1.2 × 10 ¹⁹/m ², greatly improving flame retardant efficiency and pollutant adsorption capacity, and improving performance by more than 30% compared to conventional products.

-Low moisture and low moisture absorption: moisture content ≤ 0.3% (top grade ≤ 0.1%), moisture absorption rate ≤ 0.5% (25 ℃, RH85%，24h）， It is not easy to clump during storage and use, ensuring production continuity and product stability.

3. Exclusive performance adaptation for high-end scenarios

-Flame retardant upgrade experience: precise decomposition temperature of 345 ℃, heat absorption per unit mass of 81.5kJ/mol, 25% higher than conventional magnesium hydroxide flame retardant efficiency, smoke density (DS) ≤ 50 during combustion, halogen-free and non-toxic gas release, suitable for fields with high requirements for flame retardancy and environmental protection such as electronics, semiconductors, aerospace, etc., easily passing international certifications such as UL94 V0 (1.6mm) and IEC 60695.

-Mild and precise neutralization: The pH value of the 10% aqueous solution is 9.2-9.8, which is weakly alkaline and has excellent buffering performance. When neutralizing acidic substances, the reaction is gentle, and the pH value fluctuates by ≤± 0.3. It is suitable for scenarios such as pharmaceutical acid fast preparations and precision chemical neutralization reactions, to avoid product failure caused by local alkalinity.

-High end plastic rubber: used for engineering plastics (PC, PA, PBT), special rubber and other high-end products, such as automotive electronic components, aerospace interior parts, etc., to achieve efficient flame retardancy and environmental compliance without affecting the material's mechanical properties (tensile strength, impact toughness).

2. In the fields of medicine and food

-Pharmaceutical excipients: Used as raw materials for antacids, pharmaceutical preparations for relieving excessive stomach acid (such as gastric mucosal protectants, acid fast chewable tablets), gently neutralize stomach acid without affecting intestinal microbiota balance, and comply with USP (United States Pharmacopeia) and Ph.Eur. (European Pharmacopoeia) standards.

-Food additives: used as pH regulators and preservatives in food products such as dairy products, beverages, and baked goods, to regulate product acidity and extend shelf life, in compliance with GB 25579-2010 (China) and FDA 21 CFR Part 184 (USA) food additive standards.

-Health product raw materials: As a magnesium supplement raw material, magnesium content ≥ 41%, easily absorbed by the human body, suitable for calcium tablets, compound nutrients and other health products, meeting the purity and safety requirements of the global health product industry.

3. Precision chemical and environmental governance fields

-Precision chemical synthesis: As a catalyst carrier and organic synthesis neutralizer, it is used in the synthesis process of pharmaceutical intermediates, high-end coating additives, etc., to avoid impurities interfering with the reaction process, improve product yield and purity, and adapt to the strict requirements of the fine chemical industry.

-High end water treatment: used for the preparation of electronic grade pure water, purification of pharmaceutical water, removal of trace fluoride and heavy metal ions in water, and achieving UPW (Ultra Pure Water) standard to meet the water requirements of the semiconductor and pharmaceutical industries.

-Deep flue gas treatment: applied to deep desulfurization and denitrification of flue gas in waste incineration plants and chemical enterprises, efficiently removing SO ₂, NO ₓ, and dioxin pollutants. The purified flue gas emission indicators are better than the EU EEA standards, and the by-products can be recycled and reused.

4. Other high-end scenarios

-Cosmetics raw materials: used for skincare products, toothpaste and other products, as a pH regulator and adsorbent, gentle and non irritating, capable of adsorbing skin surface odors and oils, in compliance with the EU EC 1223/2009 cosmetics regulation standards.

-High end coatings and adhesives: used as anti settling agents and flame retardant additives in aviation coatings, high-end architectural coatings, solvent-free adhesives, to enhance product weather resistance, flame retardancy, and stability, suitable for high-end building materials, aerospace and other fields.

Frequently Asked Questions (FAQ)

Q1: What are the core differences between high-purity magnesium hydroxide and conventional industrial grade products?

A: The core differences are reflected in purity threshold, impurity control, and scenario adaptation: the purity of conventional industrial grade products is mostly 98.0% -99.0%, and the content of impurities (Fe, Ca, heavy metals) is in the ppm to thousand ppm range, suitable for scenarios such as ordinary flame retardant and wastewater treatment; High purity magnesium hydroxide has a purity of ≥ 99.5%, with key impurities (Fe, heavy metals) controlled within 1ppm and ionic impurities (Cl ⁻, SO ₄² ⁻) ≤ 20ppm. It is designed specifically for high-end scenarios such as electronic semiconductors, pharmaceuticals, and food that are sensitive to purity, and can avoid product failure and performance fluctuations caused by impurities.
