Henan Daye Metallurgy Casting Material Co. Ltd. produces hollow glass microspheres from soda‑lime borosilicate glass. The listed true density spans 0.15‑0.60 g/cm³, and particle sizes are described as lightweight spherical particles without a precise range. These microspheres are positioned as functional fillers for plastics, coatings and drilling fluids.
In the coatings industry the particles improve flow, reduce VOC emissions and enhance wear resistance, while in drilling fluids they provide sound absorption and thermal insulation. Typical industry practice groups microspheres into low‑density (0.15‑0.30 g/cm³) and medium‑density (0.30‑0.60 g/cm³) grades, which influence viscosity and thermal stability. The spherical, vitrified surface gives good fluidity during mixing and contributes to low water absorption, usually below 0.1 %. Standard specifications also cite a compressive strength of 30‑80 MPa for high‑grade bubbles, although the supplier’s exact values are not disclosed.
Buyers such as paint manufacturers, automotive interior component makers and prefabricated board producers often request the product in bulk polypropylene bags or sealed drums. The public listing does not state a minimum order, so importers should ask for the MOQ, payment terms and preferred Incoterms. The supplier is listed under the harbour trust tier, but response data is missing; therefore direct communication to confirm lead time and factory capacity is advisable. Shipping will most likely depart from a Chinese port such as Shanghai or Ningbo, with transit time depending on destination and customs procedures.

Henan Daye Metallurgy Casting Material Co. Ltd. is based in Red Light Industrial Park, Henan, 464000, China. The company appears under the harbour trust tier, confirming that its registration details have been verified, although no response rate or average response time is publicly recorded. Its profile highlights the production of hollow glass microspheres for a variety of industrial sectors, but does not disclose production capacity, certifications or client references.
The listing notes that the microspheres are chemically inert, non‑combustible and exhibit high thermal stability, making them suitable for use in paints, mortars and composite panels. No explicit information on MOQ, lead‑time, payment conditions or export experience is provided, so prospective buyers should engage the supplier directly to obtain those specifics and to request sample testing data.
Hollow Glass Microspheres are lightweight spherical particles with true densities of 0.15–0.60 g/cm³, widely used as functional fillers in plastics, coatings, construction materials, and drilling fluids. These glass bubbles offer excellent thermal insulation, sound absorption, and cost-effective weight reduction across automotive, aerospace, and marine industries. Premium grades command higher pricing per metric ton, with trade volumes significant in global mineral and industrial chemical supply chains.

Prior to ordering, ask the supplier for a Certificate of Analysis that includes true density, particle‑size distribution and any applicable ASTM test results. Confirm that the manufacturing process follows consistent quality controls and that any third‑party audits have been performed. This documentation will help you assess whether the microspheres meet the performance criteria of your application.
Logistics for glass microspheres from Henan Daye usually involve FOB terms from a Chinese port such as Shanghai or Ningbo, with the buyer arranging freight. Because lead times are not disclosed, request an estimated production schedule and shipping window, and agree on payment terms - typically T/T or a letter of credit. Align the chosen Incoterm with your risk management policy and insurance coverage.
When the shipment arrives, conduct a visual inspection for breakage and perform bulk density and moisture content tests to verify conformity with the supplied data. Arrange for third‑party testing of compressive strength if that parameter is critical for your end use. Retain all test reports, certificates and customs documentation as part of your quality assurance records.
