Twelve specialised product lines, each regularly tested by external laboratories to ensure consistent, homogenous quality for our customers.

Red Iron Oxide
Pigments & Coatings

Red Iron Oxide

Also known as Ferric oxide, Hematite powder and Iron (III) Oxide. Widely used in a variety of applications across multiple industries.

Cenospheres
Lightweight Fillers

Cenospheres

A lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, offering exceptional performance.

Acids
Industrial Chemicals

Acids

We supply Hydrochloric, Sulphuric and Ferric Chloride Acid — essential reagents for a wide range of industrial and manufacturing processes.

Bentonite
Clays & Absorbents

Bentonite

Sodium Bentonite is an absorbent aluminium phyllosilicate. It is essentially impure clay consisting mostly of montmorillonite.

High Alumina Refractory Bricks
Refractory Materials

High Alumina Refractory Bricks

Extensively used in mining, metallurgy, cement, chemical, refinery and refractory industries for their exceptional heat resistance.

Magnetite
Iron Ore Minerals

Magnetite

A mineral whose primary component is an iron oxide containing equal amounts of iron(II) and iron(III). Found in igneous, metamorphic, and sedimentary rocks.

Soda Ash
Sodium Compounds

Soda Ash (Sodium Carbonate)

An odourless, white powder. It is stable, not toxic, explosive or flammable — making it safe and versatile for industrial applications.

Rice Husk
Biogeneous Silica

Rice Husk (Biogeneous Silica)

High-purity amorphous silica derived from rice husks (SiO₂ 87–92%), used as a lightweight filler, refractory additive, and absorbent material.

Sulphur
Industrial Minerals

Sulphur

High-purity elemental sulphur (S) 98% minimum on a dry basis. Essential for sulphuric acid manufacturing, rubber vulcanization, and agricultural applications.

Manganese Dioxide
Battery Materials & Oxidizers

Manganese Dioxide

Natural manganese dioxide (MnO₂ 70–80%, Mn 45–50%). Used in batteries, water purification, ceramics, glassmaking, and steel production.

Boric Acid
Industrial Chemicals

Boric Acid

High-purity boric acid (H₃BO₃ 99.5% min) with B₂O₃ 56% min. Used in glass, ceramics, agriculture, pharmaceuticals, and flame retardants.

Aluminium Powder
Metal Powders

Aluminium Powder

High-purity aluminium powder with Al₂O₃ at 99.20% oxide content. Used in paints, coatings, aerospace, energy, pyrotechnics, construction, and electronics.
