Fumed Silica
Ritu Dye Chem supplies fumed silica, an amorphous silicon dioxide produced by flame hydrolysis and identified by CAS 112945-52-5. The material is described as export‑grade and is offered with a surface area that ranges from 90 to 300 m² / g, a property that drives its rheology‑modifying performance. Purity is controlled to meet strict standards suitable for sensitive formulations, and the product is delivered in multi‑layer paper bags or supersacks for bulk handling. The supplier notes that the silica is lightweight, allowing easy incorporation into a variety of liquid and paste systems.
In the broader industry, fumed silica particles typically average around 0.1 µm in diameter and exhibit a bulk density of roughly 0.1‑0.2 g / cm³. These dimensions give the material a high specific surface that enhances thickening, anti‑settling and anti‑caking functions in paints, coatings, adhesives and cosmetics. Typical commercial grades maintain a moisture content below 0.5 % and a pH of 3.5‑4.5 when dispersed as a 1 % aqueous suspension, which helps preserve stability in neutral formulations. Storage is recommended in dry, ventilated conditions to prevent moisture uptake and agglomeration.
Importers of fumed silica include formulators of high‑performance coatings, sealants, rubber compounds and personal‑care products. Buyers generally request the material in bulk bags or supersacks, and they must confirm minimum order quantities, shipping incoterms and payment terms directly with the supplier. Ritu Dye Chem does not publish price or lead‑time information in the listing, so interested parties should ask for a formal quotation and any relevant certificates before placing an order.

Sourcing Fumed Silica from Ritu Dye Chem - India Import Guide
Before placing an order, confirm the exact surface area grade, purity level and any third‑party test reports the supplier can provide. Request a current certificate of analysis and, if needed, a sample for trial use to ensure the material meets your formulation requirements. Verify that the packaging size aligns with your handling capacity and that the supplier can meet any regulatory documentation you need for import.
Discuss logistics early: ask the supplier which incoterms they support (e.g., FOB, CIF) and what payment methods are accepted, such as T/T or L/C. Lead‑time estimates are not listed, so obtain a realistic production and shipping schedule before committing. Clarify whether the supplier can arrange container loading for supersacks or if smaller bag shipments are preferred.
Upon receipt, arrange a third‑party inspection to check bulk density, moisture content and particle size distribution against the specifications you have approved. Retain the MSDS, COA and any test certificates for customs clearance and quality assurance. Maintaining a documented inspection record will help you demonstrate compliance with your own product standards and with import regulations.
