Application engineering across 23 global industries
Sree Sai Mineral Industries processes hydrous, washed, calcined, spray-dried, and crude/raw kaolin clay into industry-specific grades engineered for whiteness, particle size, viscosity, and purity. Our in-house laboratory and application engineering team work directly with clients to match mesh size, brightness, and rheological properties to the exact performance requirements of each end-use, from ceramics and paper to pharmaceuticals and foundry sand.
Explore the 23 industries below to see how our mineral grades are engineered to perform in your specific application.
Ceramic Industry
Our washed and hydrous kaolin grades are refined to low iron and titania content, giving tiles, sanitaryware, porcelain, and fine bone china a bright, consistent fired-white body. Controlled particle size distribution improves green strength and casting rate in slip-cast production, reducing rejection rates. We tailor plasticity and shrinkage behavior to match each ceramic body formulation.

Paper Industry
High-brightness hydrous kaolin is engineered as both coating pigment and filler for paper and paperboard, improving opacity, smoothness, and print gloss. Precise particle sizing enhances ink receptivity and surface finish on coated grades, while lower-cost filler grades boost bulk and reduce fibre consumption without sacrificing brightness.

Paint & Coating Industry
Calcined and hydrous kaolin extenders replace a portion of costlier titanium dioxide while maintaining opacity and hiding power in decorative and industrial coatings. These grades also improve scrub resistance, gloss control, and film integrity, and their flat, plate-like particles help fine-tune viscosity and sag resistance during application.

Rubber Industry
Hard and soft calcined kaolin grades act as reinforcing and semi-reinforcing fillers in tyre, footwear, hose, and industrial rubber compounding, improving tensile strength, abrasion resistance, and tear resistance. Uniform particle size and low moisture content ensure smooth dispersion in the rubber matrix and consistent vulcanization behavior batch after batch.

Plastic & Polymer Industry
Surface-treated kaolin grades are used as functional fillers in PVC compounds, masterbatches, and engineering plastics to improve stiffness, dimensional stability, and impact strength. As a cost-effective extender for polymer resin, our grades are calibrated for consistent loading levels without compromising melt flow or surface finish.

Calcined Kaolin Industry
Our in-house rotary and flash calcination lines convert washed kaolin into high-brightness, low-abrasion grades with reduced structural water, unlocking performance in demanding technical applications. By controlling calcination temperature and dwell time, we produce both soft-structured and fully calcined hard grades tuned for opacity, thermal stability, and reduced binder demand.

Cable & Wire Industry
Calcined kaolin filler is engineered for PVC and XLPE insulation and jacketing compounds, delivering high dielectric strength and stable electrical insulation resistance. Low moisture pickup and fine, uniform particle size give cable compounds a smoother extrusion surface and consistent thermal performance under load.

Fiberglass Industry
High-purity kaolin serves as a source of alumina and silica in fiberglass batch composition and as a functional filler in glass-fibre reinforced composites. Consistent chemistry and low grit content support stable fiber drawing, while filler-grade kaolin in laminates limits resin absorption and improves dimensional stability of the finished composite.

Refractory Industry
Raw and calcined kaolin with high alumina content is supplied for refractory bricks, monolithic castables, and kiln furniture that must withstand repeated thermal cycling. Excellent thermal shock resistance and low shrinkage at high temperature make these grades reliable in ladle linings, furnace linings, and other high-heat installations.

Cement Industry
Our calcined kaolin (metakaolin) grade is a highly reactive pozzolanic additive used as a supplementary cementitious material, improving compressive strength and reducing permeability in blended cement and concrete. It also helps mitigate alkali-silica reaction and improves long-term durability of structural concrete.

Adhesives & Sealants Industry
Fine particle-size kaolin extends adhesive and sealant formulations economically while maintaining bond strength, and its plate-like structure helps control thixotropy and sag resistance in vertical applications. This gives formulators reliable open time and consistent viscosity across production batches.

Welding Electrode Industry
Specialty processed kaolin functions as a flux and binder ingredient in welding electrode coatings, supporting smooth arc stability and controlled slag formation and removal. Consistent moisture content and fine grinding ensure uniform extrusion of the flux coating onto the electrode core wire.

Iron & Steel Industry
High-purity refractory-grade kaolin is supplied for ladle linings, mould flux, and continuous casting applications where thermal stability and chemical inertness against molten metal are essential. Precise alumina-silica ratios help control viscosity and heat transfer during the casting process.

Poultry & Cattle Feed Industry
Food-grade mineral additives are used as anti-caking agents and carriers in poultry and cattle feed formulations, keeping premixes free-flowing and evenly distributed. Their fine, consistent particle size improves nutrient carrier efficiency and pellet quality in bulk feed manufacturing.

Agriculture Industry
Refined kaolin grades act as carriers and anti-caking agents in granular fertilizer and pesticide formulations, keeping products free-flowing during storage and transport. Fine particle-film grades are also used in foliar applications to reflect excess heat and reduce pest and sun-stress damage on crops.

Cosmetic Industry
Micronized, cosmetic-grade white kaolin is processed to strict microbial and heavy-metal specifications for use in face masks, loose and pressed powders, and oil-control formulations. Its natural absorbency and soft, silky feel make it a preferred mattifying base ingredient for skin-care and personal-care products.

Pharmaceutical Industry
Pharmaceutical-grade kaolin, processed to meet pharmacopoeia purity standards, is used as an excipient, tablet filler, and adsorbent base in oral formulations. Its high adsorption capacity and inert chemical nature make it well suited for topical and oral pharmaceutical applications requiring strict quality documentation.
