Import Aluminum Hydroxide Fire Retardant — Buy in Bulk from Supplier in China

Aluminum hydroxide fire retardant from Jinan Chenxu Chemical Co., Ltd. is a hydrated alumina-based inorganic flame retardant supplied in three standard mesh grades: 325, 2000 and 3000 mesh. The product line carries three brand grades, AH-1, AH-2 and AH-3, with Al2O3 content at 64.5%, 64.0% and 63.5% respectively, and fire loss capped at 35% across all grades. Impurity ceilings vary by grade: SiO2 at 0.02-0.08%, Fe2O3 at 0.02-0.05%, and Na2O at 0.4-0.6%. The chemical composition is calculated after baking at 110 ± 5°C for two hours, with impurity content rounded per GB8170.

The physical form is a white crystalline powder whose flame-retardant action depends on endothermic decomposition, releasing water of crystallisation at approximately 200°C to cool the substrate and dilute combustible gases. The 325 mesh suits general compounding where moderate dispersion suffices, while 2000 and 3000 mesh grades target applications demanding finer particle distribution and improved mechanical properties in the polymer matrix. Standard packaging is 25 kg plastic woven bags, with 20 metric tons loading a 20-foot container. The material is non-toxic during decomposition, producing only water vapour and alumina residue rather than halogenated or phosphorus by-products.

Primary buyers include compounders of thermosetting plastics, synthetic rubber processors, coating manufacturers and construction material producers seeking halogen-free flame retardancy. The supplier is based in Jinan, Shandong Province, with an imported-tier classification, though response rate and average response time data are not available. Buyers should confirm current MOQ, lead time, Incoterms and certificate of analysis availability directly with the supplier before placing orders.

Jinan Chenxu Chemical Co., Ltd. is located at 138-1 Jiwei Road, Jinan 250022, Shandong Province, China. The supplier holds an imported-tier classification on the platform and a harbor trust tier, which is the baseline verification level. The response rate is recorded at 0.00% with zero average response hours, indicating that the supplier has either not engaged with buyer enquiries through the platform or the data has not been captured. No additional profile information, such as year established, employee count, annual revenue, or factory certification, is provided in the source data.

The listing focuses specifically on aluminum hydroxide fire retardant with technical indices and application guidance, suggesting specialisation in inorganic chemical additives rather than broad commodity trading. Buyers should treat the limited engagement signals as a prompt to conduct independent due diligence, including direct verification of business registration, production capacity and quality management systems. The supplier's Shandong location places it within one of China's major chemical manufacturing corridors, though this geographical advantage does not substitute for verified credentials.
