Expanded pearlite

Shandong Fujing Refractory Co., Ltd. supplies expanded perlite, a lightweight volcanic glass aggregate produced by rapid heating of raw perlite. The material has a reported bulk density of 80 kg m‑3 and can withstand temperatures up to 1320 °C, making it suitable for high‑temperature insulation. Its low thermal conductivity and porous structure provide effective heat resistance while remaining easy to handle. The supplier markets the product for construction, horticulture and various manufacturing processes.

In the industry, expanded perlite commonly exhibits bulk densities between 70 and 120 kg m‑3, so the supplied value falls within the usual range. Moisture content is typically kept below 2 % to preserve insulating performance, and particle sizes are often graded from 2 mm to 5 mm for concrete applications. The material’s high refractoriness and low water absorption are standard attributes that allow it to replace heavier aggregates in lightweight concrete. These characteristics align with common specifications for thermal insulation and soil amendment products.

Builders, greenhouse operators and manufacturers of filtration media purchase expanded perlite to reduce weight, improve aeration and enhance thermal barriers. Shandong Fujing Refractory offers the product under FOB or CIF terms from ports in China, but does not disclose specific minimum order quantities or lead times, so these details must be clarified with the supplier. Prospective importers should request the material’s certification, moisture‑ratio test results and a sample batch before finalising the contract.

Shandong Fujing Refractory Co., Ltd. is located on Fuzhou Road, Qingdao, Shandong, China, postal code 266071. The company appears in the harbour trust tier, indicating a verified registration, and its response rate is recorded as 0 % with no average response time. No further operational metrics are disclosed in the supplier profile.

The firm’s product line centres on expanded perlite, promoted for lightweight concrete, horticultural conditioning and filtration uses. The listing does not provide details on production capacity, years of operation or specific client references. Buyers are advised to request sample material and any test reports that substantiate the performance claims.
