Import Dn-15 Low Porosity — Buy in Bulk from Supplier in China

The Dn-15 low porosity material is a dense refractory product designed for high-temperature industrial environments, with a nominal diameter of 15 mm and a porosity level below 15% as indicated in the source. It is composed primarily of mullite and flint, materials known for thermal stability and resistance to thermal shock. The product is rated to withstand loads of 0.2 MPa at temperatures up to 1420°C, making it suitable for applications where structural integrity under heat stress is critical.

This material typically exhibits a bulk density between 2.6 and 2.8 g/cm³, consistent with standard industrial refractories of this class. Its low porosity reduces permeability to molten slag and gases, extending service life in kilns and furnaces. While the listing does not specify exact alumina content, typical mullite-flint blends contain 65-75% Al2O3, which contributes to refractoriness and chemical inertness. The product is not coated or glazed, and surface finish is sintered, not machined.

It is commonly used in ceramic kiln linings, glass melting chambers, and metallurgical furnace zones where thermal cycling is frequent. Buyers include industrial ceramic manufacturers, foundries, and refractory installers sourcing bulk material for lining construction. Packaging is typically in 25 kg paper bags or bulk pallets, with standard Incoterms such as FOB Dalian or CIF destination ports available upon request. MOQ and lead time must be confirmed directly with the supplier.

Shenyang Shenlong Industry & Commerce Co., Ltd. is registered in Shenyang, Liaoning, China, with a physical address at Bao An Si Street 18-3. The listing classifies the supplier as imported and harbor-tier, indicating verified export capability and logistics readiness. There is no public information on company history, workforce size, or annual turnover. The supplier has no recorded response rate or average response time, suggesting limited digital engagement but not necessarily operational incapacity.

The supplier specializes in industrial refractory materials and appears to source or distribute Dn-15 low porosity products for export. No certifications, client lists, or production facility details are provided. The absence of response metrics does not confirm inactivity; it may reflect operational focus on bulk trade rather than digital inquiry handling. Buyers should verify production or sourcing origin directly before placing orders.
