Aluminium Hydroxide Industrial FR Grade is one of the most eco-friendly halogen-free inorganic flame retardant materials and critical alumina precursor raw material in modern industrial raw material system, and Linkwin implements full precipitation synthesis, multi-stage washing, filtration and drying production control system for this product, separating production lines for flame retardant grade and general industrial grade to avoid cross-contamination, ensuring stable whiteness, consistent particle distribution and low soluble impurity content for diversified downstream manufacturing demands. Our aluminium hydroxide is white fine powder with weak amphoteric property, decomposing endothermically at high temperature to release water vapor, dilute combustible gas and form insulating oxide protective layer, achieving physical flame retardant and smoke suppression effect without toxic halogen fumes, complying with global environmental protection flame retardant regulations. Strict control over silica, ferric oxide and trace heavy metals effectively avoids adverse influence on whiteness, insulation performance and finished product stability for high-end composite formulation.

In flame retardant application field, FR grade aluminium hydroxide is the mainstream halogen-free flame retardant filler added to PVC, PP, PE, epoxy resin, silicone rubber, architectural fireproof coating, cable insulation material and artificial marble composite, reducing combustion heat release, inhibiting smoke generation and preventing flame spread, widely favored by environmentally compliant material manufacturers. For metallurgical industry, industrial grade aluminium hydroxide is calcined to produce metallurgical alumina as raw material for electrolytic aluminium smelting; it is also used to manufacture high-purity alumina for refractory material, polishing powder and electronic ceramic substrate production. In environmental protection water treatment sector, it acts as pH neutralizer for acidic wastewater, auxiliary flocculant for suspended solid sedimentation and heavy metal ion adsorption removal agent. Many overseas buyers frequently complain about uneven particle size, high iron impurity leading to yellow discoloration and poor flame retardant uniformity from inferior suppliers; our precise synthesis and classification screening process completely solve these quality defects, stabilizing your finished product qualification rate and market environmental compliance advantage.

Standard packaging is 25kg inner PE liner outer woven bag, jumbo bag bulk container shipment is customizable for large-volume orders to cut unit logistics expenditure. We maintain adequate year-round inventory reserves to shorten order lead time and eliminate raw material shortage shutdown risks for your factory. Complete export documents including batch COA, MSDS and product test report can be issued rapidly to streamline import customs clearance globally. Our sales team can tailor accurate FOB and CIF quotations based on order quantity and destination port, support free sample delivery for formulation trial before bulk purchase, and offer technical guidance for filling proportion matching in flame retardant formulas. Choosing Linkwin as your aluminium hydroxide supplier effectively reduces intermediate procurement costs, stabilizes finished product quality and builds sustainable long-term supply cooperation advantage.
