Description
Colloidal Silicon Dioxide Supplier & Exporter in India
Colloidal Silicon Dioxide is one of the lightest powders in routine industrial use, and its value comes entirely from surface area. Sub-micron amorphous particles coat larger ones, break up the friction between them and let a sticky blend flow like sand – which is why a fraction of a percent transforms the behaviour of a difficult powder.
Rexus Pharma Chem LLP supplies Colloidal Silicon Dioxide in bulk to pharmaceutical and nutraceutical manufacturers, food processors, cosmetic companies and coating and adhesive formulators in India and export markets. Minimum order quantity is 500 kg.

Frequently Asked Questions
What is the difference between hydrophilic and hydrophobic grades?
Hydrophilic grades disperse readily in water and are the usual choice as glidants and thickeners in aqueous systems. Hydrophobic grades are surface-treated to repel water and are used where moisture protection or defoaming is needed. Tell us the application and we will quote the right type.
How much is used as a glidant?
Typical inclusion is 0.1 to 1 percent of the blend. Very little is needed, which is why the material is dosed carefully and blended thoroughly.
Is it the same as fumed silica?
Yes. Colloidal Silicon Dioxide, fumed silica and colloidal silica are all names for the same amorphous material.
What is the minimum order quantity?
The minimum order quantity is 500 kg. Given how light the material is, this represents a substantial volume, so confirm your storage space when planning the order.
Do you supply COA and MSDS?
Yes, with every consignment.
