Import Aluminum Hydroxide For Solid Surface — Buy in wholesale FOB from Supplier in China

Aluminum trihydrate, ATH, Al(OH)3, serves as the principal flame retardant and mineral filler in solid surface manufacturing, where it is compounded with acrylic or polyester resins to produce non-porous, thermoformable sheets. Zibo Jianhua Building Materials Co., Ltd supplies this material from Shandong Province, China, for composite and construction applications. The source indicates 99.0% purity in white crystalline powder form, though buyers should confirm whether this figure represents assay on a dry basis or as-received material, and whether it accounts for potential surface moisture or coating additives.

The solid surface industry demands specific physical properties in ATH filler: controlled median particle size (typically 5-45 μm for fine finish surfaces, coarser grades for casting), narrow particle size distribution to ensure uniform resin loading and minimal sink marks, and low electrolyte content to prevent resin cure inhibition. Whiteness (Hunter L* value) typically exceeds 95 for light-colored surfaces. Surface treatment with stearic acid or silane coupling agents may be applied to improve dispersion in hydrophobic resin matrices, though the source does not specify whether Zibo Jianhua offers treated grades. The refractive index of ATH (1.57) closely matches that of acrylic resin, permitting high filler loading while maintaining translucency.

Buyers include solid surface fabricators, artificial stone (renzao shi) producers, and manufacturers of cultured marble and onyx. The material also finds application in vinyl composite tile, wire and cable insulation, and epoxy formulations where halogen-free flame retardancy is required. For import, discuss with Zibo Jianhua whether they supply surface-treated or untreated grades, what packaging protects against moisture pickup (ATH is hygroscopic and moisture degrades solid surface cure), and whether they provide technical guidance on optimal loading levels and mixing procedures for specific resin systems. The Harbor trust tier and zero response rate indicate limited platform engagement, necessitating proactive direct outreach.

Zibo Jianhua Building Materials Co., Ltd operates from Zhangdian District, Liuquan Road 296, Zibo, Shandong Province, 255000, China. Zibo is an established industrial hub with significant chemical and ceramic manufacturing infrastructure, providing reasonable access to aluminum hydroxide from nearby alumina refineries in Shandong. The supplier carries a Harbor trust tier and records 0.00% response rate with zero average response hours, indicating no tracked inquiry history through the platform. This lack of engagement data should not automatically disqualify the supplier but requires buyers to conduct thorough independent due diligence.

The company profile presents itself as a building materials specialist rather than a broad chemical trading house, which may imply focused application knowledge in construction composites. No manufacturing assets, warehouse specifications, quality management certifications, or laboratory capabilities are disclosed in the available data. The source description mentions ISO and SGS certifications without identifying specific standards, scopes, or accreditation bodies. Buyers should verify the actual certificate numbers, validity dates, and whether these apply to the supplier's quality system, specific products, or upstream manufacturing partners. The absence of disclosed history, revenue, employee count, or named clients means these cannot be relied upon and must be investigated directly.
