Fumde Silica, also known as White Carbon Black, is a precipitated amorphous silica powder supplied by Hangzhou Bayee Chemical Co., Ltd. in Zhejiang, China. It consists of SiO2 with a molecular weight of 60.08 g/mol and melts at 1610 °C. The material meets a minimum standard SiO2 content of 99.8 % and a specific surface area between 176 and 225 m2/g. Density at 25 °C is recorded as 2.6 g/cm3 and the refractive index is 1.544.
The powder is delivered as a white solid colloidal micro‑particle with a pH of 3.6‑4.5 in aqueous suspension. Burning loss does not exceed 2.5 % and volatiles at 105 °C are limited to 3.0 %, indicating low organic residue. Typical particle size for precipitated silica ranges from 10 to 30 µm, which supports its use as a reinforcing filler. In the rubber and elastomer industry, such surface area and purity levels improve tensile strength and thermal stability.
Primary applications include reinforcement in tire rubber, coatings, inks and specialty chemical formulations. Buyers such as automotive parts manufacturers, construction material producers and packaging coating firms usually request bulk shipments in 25 kg drums, with the possibility of customised packaging. Trade terms, incoterms and lead times are not disclosed in the listing and should be confirmed directly with the supplier. Because the supplier’s response rate is currently zero, importers are advised to verify the company's credentials and request a recent certificate of analysis before placing an order.

Importers should request a current certificate of analysis confirming SiO2 purity ≥99.8 % and specific surface area within 176‑225 m2/g. Verification of particle size distribution and moisture content is also advisable, as these affect handling and performance. Ensure the supplier provides a recent safety data sheet and any applicable export permits before finalising the purchase.
The product is normally packed in 25 kg steel drums; confirm whether larger bulk containers or alternative packaging are acceptable for your shipment. Discuss incoterms such as FOB Hangzhou port or CIF Shanghai, and clarify the expected lead time, which is not stated in the listing. Payment terms are typically negotiated as T/T against a letter of credit for first orders, but should be agreed directly with the supplier.
Arrange for an independent third‑party inspection to verify bulk properties, including density and burning loss, before loading. Request a pre‑shipment sample for laboratory testing against the stated specifications. Retain documentation such as the test report, packing list and bill of lading for customs clearance and quality assurance.
