Import Acicular Wollastonite Powder — Buy in wholesale FOB from Supplier in China

Xinyu City Southern Wollastonite Co., Ltd. supplies acicular wollastonite powder, a calcium silicate mineral with needle-like particle morphology derived from wollastonite deposits in Jiang Forgeographic region. The acicular structure, characterized by high aspect ratio, provides reinforcement functionality in composite matrices where mechanical strength and dimensional stability are required. The material is supplied as a functional filler and additive for ceramics, paints, coatings, plastics, and refractory applications. The supplier emphasizes low oil absorption and brightness characteristics as distinguishing features of this grade.

The mineral composition is calcium silicate, CaSiO3, with the acicular habit resulting from natural crystal growth conditions in metamorphosed carbonate rocks. High-aspect-ratio particles interlock within polymer and ceramic matrices, improving flexural strength, reducing shrinkage during firing or curing, and enhancing thermal resistance compared to equidimensional fillers. Low iron content relative to standard ground wollastonite contributes to brightness retention in white or light-colored formulations. The needle-like morphology also influences rheological properties, providing thixotropic behavior in liquid systems without excessive viscosity increase.

Primary application sectors include construction materials, automotive components, and electronics packaging where thermal and mechanical performance specifications drive filler selection. Ceramic manufacturers use wollastonite as a fluxing agent and to improve green strength. Paint and coating formulators value the low oil absorption for reduced binder demand and cost optimization. Plastics compounders incorporate acicular wollastonite for stiffness and heat distortion temperature improvement. Xinyu City Southern Wollastonite Co., Ltd. operates from Jiangxi Province, a known wollastonite-producing region, with harbor trust tier status. Buyers should verify current production capacity, typical aspect ratio distributions, and available grind sizes before specification.

Xinyu City Southern Wollastonite Co., Ltd. is located at Renhe Village, Xiacun Town, Xinyu, Jiangxi Province, 338021, China. The company holds a harbor trust tier, indicating basic platform verification. No response rate data is available, suggesting buyers should initiate contact with田early in procurement planning to assess communication reliability. The listing provides no information about establishment year, employee count, annual production volume, or mine ownership status. The address places the company in Xinyu, within Jiangxi Province's known wollastonite belt.

The supplier describes itself as sourcing from China's premier wollastonite deposits, though specific mine locations or extraction methods are not detailed. Product claims center on acicular morphology, low iron content, and brightness advantages over competing ground grades. No ISO certifications, SGS reports, or other third-party quality documentation is confirmed in the available data, despite mention of such certifications in promotional material. Buyers should treat uncorroborated certification claims as requiring direct verification. The company's specialization appears focused on wollastonite products rather than diversified mineral processing.
