Foundry Casting

Silica is one of the refractory materials. It has a higher melting point than iron, copper and aluminum. The refractoriness helps to resist high temperatures without breaking down or fusing thus facilitating to get sound casting. This enables castings to be produced by pouring molten metal into moulds made out of silica sand.

Ceramics

Silica that has been ground to fine size is an ingredient of most clay bodies and is a major constituent of ceramic glazes. Typical everyday products include tableware, sanitaryware, ornaments and wall and floor tiles.

Water Treatment

- Filter media
Silica sand is used frequently in water filtration systems. It is the principal filtration medium used by the water industry to extracts solids from wastewater. Filter silica sand consists of hard, durable, and dense grains of predominantly siliceous material that will resist degradation during handling and use.

Glassmaking

- Standard and specialty glass
Silica sand is one of the key components for almost all common commercial glasses. It is used to produce flat glass for building and automotive use, container glass for foods and drinks, and tableware. Besides that, it also used to produce other specialty product such as test tubes and other scientific tools, incandescent and fluorescent lamps, television and so on.

Drymix

- Mortars, Tile adhesive, Flooring, Non shrink grout, Hardener, Tile Grout & Roofing Tile
Silica sand is the main structural component in a wide variety of building and construction products. It can be used in flooring compounds, mortars, specialty cements, stucco, roofing shingles, skid resistant surfaces and asphalt mixtures to provide packing density and flexural strength without badly affecting the chemical properties of the binding system. On the other hand, it also carry out as a functional extender to add durability and corrosion resistance and weathering properties in epoxy based compounds, sealants and caulks.

Golf Course

- Bunker sand & Putting sand
Silica sand plays a crucial role, especially in the worldwide market with growing demand for golf courses. The sizing and shape enables the sand to be consolidated and form a more uniform surface.

Paint and Coatings

- Non-slip aggregate
Paint formulators select micron-sized of silica sands to improve the appearance and durability of architectural and industrial paint and coatings. High purity silica contributes essential performance properties such as brightness and reflectance, color consistency, and oil absorption. In the aspect of architectural paints, silica fillers improve tint retention, durability, and resistance to dirt, mildew, cracking and weathering. Low oil absorption allows increased pigment loading for improved finish color. In the aspect of marine and maintenance coatings, the durability of silica imparts excellent abrasion and corrosion resistance.

Metallurgical

It plays an important role in the production of a wide variety of ferrous and non-ferrous metals. In the aspect of metal production, silica sand work as a flux to lower the melting point and viscosity of the slag to make them more reactive and efficient. Lump silica is used either alone or in combination with lime to achieve the desired base/acid ratio required for purification. These base metals can be further refined and modified with other components to attain specific properties such as high strength, anti-corrosion/corrosion resistance or electrical conductivity. Besides that, ferroalloys are crucial to specialty steel production and silica sand is used by the steel and foundry industries for de-oxidation and grain refinement.

20-30 Sand

Graded according to the ASTM C778-3 standard, is a primary choice for hydraulic cement testing due to its consistent quality and precise grain size distribution. Composed of over 98% natural silica (Perak Source), this sand undergoes strict grading to ensure that the sand provides uniform results in hydraulic cement testing. Unlike natural sand, which may have variable grain sizes, shapes, and moisture content. 20-30 Sand offers uncrushed, rounded grains with a moisture content below 0.1%, ensuring reliability and accuracy in laboratory conditions. Its consistency and adherence to ASTM standards make it the preferred choice for precise and repeatable testing.
