Import 99% Purity Magnesium Hydroxide — Buy in wholesale FOB from Supplier in China

This 99% purity magnesium hydroxide, Mg(OH)2, is an inorganic flame retardant and smoke suppressant produced by Hefei Zhongke Flame Retardant New Materials Co., Ltd in Anhui Province, China. The material decomposes endothermically at approximately 330 to 350 degrees Celsius, releasing water vapour that dilutes combustible gases and cools the polymer surface. It is supplied in powder form for bulk industrial procurement, with the 99% purity level indicating low levels of calcium, iron, and other metallic impurities that could compromise thermal stability or colour in finished compounds. The supplier is based in Feidong Economic Development Zone, Hefei, though buyers should note the current response rate is 0.00% and response time data is not yet established.

Magnesium hydroxide of this grade typically conforms to industrial flame retardant specifications rather than pharmaceutical or food-grade standards, though the exact pharmacopeial compliance status should be verified directly with the supplier. The powder particle size distribution, median diameter (D50), and surface area are critical parameters that determine dispersion behaviour in polymer matrices such as polyethylene, polypropylene, and ethylene-vinyl acetate. Typical surface treatment with stearic acid or silane coupling agents may be available to improve compatibility with hydrophobic polymers, though this supplier's specific coating options are not detailed in the available data. The compound's_void of halogens makes it suitable for low-smoke, zero-halogen cable compounds where regulatory requirements prohibit antimony trioxide or brominated systems.

Primary buyers include compounders of wire and cable insulation, polyolefin film and sheet producers, and manufacturers of thermoplastic elastomers requiring non-toxic fire retardancy. Water treatment specialists also procure this grade for pH adjustment and heavy metal precipitation, where the buffering capacity and solubility product of magnesium hydroxide offer controlled alkalinity. Pharmaceutical applications, such as antacid active pharmaceutical ingredient production, would require additional certification and testing beyond the industrial grade described here. Buyers should confirm packaging formats, typically 25 kg bags or bulk containers, and whether the supplier offers technical data sheets with loss on ignition, specific surface area, and particle size analysis before placing trial orders.

Hefei Zhongke Flame Retardant New Materials Co., Ltd operates from 36 Xianghe Road in the Feidong Economic Development Zone, Hefei, Anhui Province, postal code 231600, China. The company's location in an established economic development zone suggests access to industrial infrastructure and logistics networks serving eastern China's manufacturing corridor. The trust tier is classified as harbour, and buyers should be aware that the response rate is currently recorded at 0.00% with no average response time data available, which means direct communication channels may require-tiered verification before order commitment.

The supplier's product listing emphasises magnesium hydroxide for flame retardant, smoke suppression, water treatment, and pharmaceutical precursor applications, though buyers should independently confirm which grades and certifications are actually stocked. No information is provided about factory size, annual production capacity, in-house testing laboratories, or export experience to specific markets. The listing does not state ISO 9001, ISO 14001, or REACH registration status, so compliance documentation should be requested explicitly. Buyers are advised to conduct supplier verification through third-party audit or video inspection before advancing beyond sample orders, given the absence of response signals.
