Below are key applications and tailored solutions.<\/p>\n<h3 id=\"toc-bd4840b73b936651e6b666048177014d\">Flame Retardant in Plastics and Construction<\/h3>\n<p>In the construction sector, magnesium hydroxide is added to PVC, polypropylene, and cable compounds as a non-halogen flame retardant. It decomposes endothermically at 330\u00b0C, releasing water vapor and forming a protective magnesium oxide layer. <strong>Solu\u00e7\u00e3o:<\/strong> Use surface-treated grades with particle sizes of 1-5 microns for optimal dispersion and mechanical properties.<\/p>\n<h3 id=\"toc-eb57ac0905b1f7b9ab83ad0202451c4e\">Wastewater Treatment<\/h3>\n<p>Magnesium hydroxide acts as a pH adjuster and coagulant in industrial wastewater treatment. It neutralizes acidic effluents and precipitates heavy metals like nickel, copper, and zinc. <strong>Solu\u00e7\u00e3o:<\/strong> Choose a slurry form (50-60% solids) for easy dosing and rapid reaction. Typical dosage is 0.5-2 kg per cubic meter of wastewater.<\/p>\n<h3 id=\"toc-80a2e0ca0a2e3f52394ce9a42a30a32d\">Pharmaceutical and Food Industry<\/h3>\n<p>As an antacid and laxative, magnesium hydroxide is used in over-the-counter medications. It also serves as a food additive (E528) for pH control. <strong>Solu\u00e7\u00e3o:<\/strong> Source USP or FCC-grade material with heavy metal limits below 10 ppm and microbial counts within pharmacopoeia standards.<\/p>\n<h3 id=\"toc-e0e19fa00b7c54d098722b69a1524f9d\">Refractory Materials<\/h3>\n<p>In steelmaking and glass production, magnesium hydroxide is calcined to produce magnesia (MgO) for refractory bricks. <strong>Solu\u00e7\u00e3o:<\/strong> Use high-purity (98%+ Mg(OH)\u2082) with low silica and iron content for superior thermal resistance.<\/p>\n<h2 id=\"toc-5b752b73f989033d565038487754e49b\">Perguntas mais frequentes (10 FAQs)<\/h2>\n<ol>\n<li><strong>What is the difference between magnesium hydroxide and aluminum hydroxide?<\/strong> Magnesium hydroxide decomposes at a higher temperature (330\u00b0C vs 200\u00b0C) and produces less smoke, making it safer for flame retardant applications.<\/li>\n<li><strong>Is magnesium hydroxide safe for human consumption?<\/strong> Yes, in regulated pharmaceutical and food grades, it is safe. It is commonly used as an antacid.<\/li>\n<li><strong>What is the typical particle size for flame retardant grade?<\/strong> Most flame retardant applications require a mean particle size of 1-5 microns. Surface treatment improves compatibility with polymers.<\/li>\n<li><strong>Can magnesium hydroxide be used in potable water treatment?<\/strong> Yes, it is approved for pH adjustment in drinking water, but must meet strict purity standards.<\/li>\n<li><strong>What is the shelf life of magnesium hydroxide powder?<\/strong> When stored in dry conditions, it has a shelf life of 2-3 years. Slurry forms should be used within 6 months.<\/li>\n<li><strong>How is magnesium hydroxide packaged for export?<\/strong> Common packaging includes 25 kg paper bags, 500 kg jumbo bags, and 1-ton bulk bags. Container liners are used for moisture protection.<\/li>\n<li><strong>What is the melting point of magnesium hydroxide?<\/strong> It decomposes before melting at approximately 350\u00b0C, releasing water vapor.<\/li>\n<li><strong>Is magnesium hydroxide biodegradable?<\/strong> It is not biodegradable but is environmentally benign as it naturally converts to magnesium carbonate over time.<\/li>\n<li><strong>What are the main impurities to check?<\/strong> Key impurities include calcium oxide, silica, iron oxide, and heavy metals (lead, cadmium, mercury).<\/li>\n<li><strong>Can magnesium hydroxide be used in agriculture?<\/strong> Yes, it is used as a soil amendment to correct magnesium deficiency and adjust soil pH.<\/li>\n<\/ol>\n<h2 id=\"toc-c36ecb0cbc915a8ee3d6d9c316a915cb\">Purchasing Considerations for Magnesium Hydroxide<\/h2>\n<p>When negotiating a purchase agreement, pay attention to the following critical aspects to avoid costly mistakes.<\/p>\n<p><strong>Specification Clarity:<\/strong> Define exact requirements for purity (typically 93-99.5%), particle size distribution (D50, D90), moisture content (below 1%), and bulk density. Include these in the contract.<\/p>\n<p><strong>Minimum Order Quantity (MOQ):<\/strong> Chinese factories often set MOQs of 10-20 metric tons for standard grades. Specialty grades may require higher MOQs. Negotiate trial orders for new suppliers.<\/p>\n<p><strong>Condi\u00e7\u00f5es de pagamento:<\/strong> Standard terms are 30% advance payment with 70% against copy of shipping documents. For established relationships, consider L\/C at sight or open account terms.<\/p>\n<p><strong>Lead Time:<\/strong> Typical production lead time is 15-30 days after order confirmation.

B2B platforms like Alibaba list verified bulk sellers.<\/li>\n<li><strong>What is the price of magnesium hydroxide per ton in 2026?<\/strong> Prices range from $250\/ton for industrial grade to $2,500\/ton for pharmaceutical grade, depending on purity and quantity.<\/li>\n<li><strong>Which magnesium hydroxide manufacturer has the best quality?<\/strong> Kyowa Chemical (Japan) and Nedmag (Netherlands) are renowned for high-purity grades. Chinese manufacturers like Shandong Sinocera offer competitive quality at lower prices.<\/li>\n<li><strong>How to find a reliable magnesium hydroxide supplier in China?<\/strong> Use Alibaba with &#8220;Verified&#8221; filter, request samples, and hire third-party inspection services like SGS for factory audits.<\/li>\n<li><strong>What is the minimum order quantity for magnesium hydroxide?<\/strong> MOQs typically range from 10-20 metric tons for standard grades. Specialty grades may require 5 tons minimum.<\/li>\n<li><strong>Is magnesium hydroxide better than aluminum hydroxide for flame retardants?<\/strong> Yes, magnesium hydroxide has higher decomposition temperature (330\u00b0C vs 200\u00b0C) and produces less smoke, making it safer for construction materials.<\/li>\n<li><strong>Can I get a free sample of magnesium hydroxide?<\/strong> Many Chinese manufacturers offer free samples of up to 1 kg, but you pay for shipping. Request via Alibaba or direct email.<\/li>\n<li><strong>What certifications should a magnesium hydroxide supplier have?<\/strong> Look for ISO 9001, ISO 14001, REACH registration, and specific grade certifications like USP or FCC.<\/li>\n<li><strong>Quanto tempo demora o envio da China para os EUA?<\/strong> Sea freight from Shanghai to Los Angeles takes approximately 20-25 days. Air freight is 5-7 days but costs significantly more.<\/li>\n<li><strong>What is the difference between light and heavy magnesium hydroxide?<\/strong> Light grade has lower bulk density (0.3-0.5 g\/cm\u00b3) and is used in pharmaceuticals. Heavy grade (0.7-1.0 g\/cm\u00b3) is preferred for industrial applications.<\/li>\n<\/ol>\n<h2 id=\"toc-11918607b664dcfe7b9c339719e44fb9\">Customs Data and Tariff Rates for Magnesium Hydroxide<\/h2>\n<p>Understanding customs classification and tariffs is essential for cost calculation.

Large factories often have rigid production lines optimized for standard grades.<\/p>\n<p><strong>Quantidades m\u00ednimas de encomenda inferiores:<\/strong> SMEs may accept MOQs as low as 1-5 metric tons, ideal for startups or specialized applications.

Large corporations may have slower decision-making processes.<\/p>\n<p><strong>Cost for Small Orders:<\/strong> For small quantities, SMEs can be more cost-effective as they avoid the overhead of large-scale operations. However, per-ton pricing may be slightly higher than large factories for bulk orders.<\/p>\n<p><strong>Risk of Consistency:<\/strong> Large factories generally have superior quality control systems and consistent output.
