What is Talc?
Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg₃Si₄O₁₀ (OH)₂. The deposits form from the transformation of high magnesium rocks by siliceous hydrothermal fluids. Talc is an ultra-versatile mineral valued for its diverse properties by a wide range of applications which makes it called the softest rock on the planet.
Hamdail P.L.C is one of the country’s largest producers of talc. Working hand in hand with customers, our process experts elaborate new product designs to meet their specific formulation requirements. Due to this constant focus on innovation Hamdail plays a key front role in its customers’ value chain.
Each talc deposit has a unique morphology and mineralogy, but our talc exhibit unique properties like water repellency, chemical inertness, platyness, and an affinity for organic substances. Its natural properties, together with the different particle sizes available, allow the user to regulate and adjust the gloss levels required. It also enables easier dispersion.
Ultra White Talc is a highly refined and pure form of talcum powder that is known for its exceptional brightness and whiteness. It is carefully processed to remove impurities, resulting in a product that has a smooth texture and a luxurious feel on the skin. Additionally, Ultra White Talc is often used in various cosmetic and personal care products due to its ability to absorb moisture and provide a soft, matte finish.
Off White Talc is a finely powdered substance that is commonly used in various industries. It is known for its off-white color, which gives it a distinctive appearance. This talc is often used in cosmetics, as it helps to absorb moisture and reduce shine on the skin. Additionally, it is also used in the production of ceramics, paints, and plastics due to its ability to improve the texture and enhance the performance of these materials.
⦁ Mohs’ scale hardness is 1 (softest rock)
⦁ Platy, lamellar
⦁ Oleophilic (natural affinity with oils)
⦁ Relatively inert
⦁ Very smooth
The above properties make talc a highly prized multi-functional filler and process enabler in an array of applications from plastics to paper, ceramics to paint.
⦁ In plastics, Talc powder for the plastic and extrusion industry is excellent filler due to its blending characteristics, thermal and electrical resistance. Moreover, talcum powder for the plastic filler is chemically inert and provides a smooth feel to the plastic surface
⦁ In pulp and paper, Talc acts as filler and coating material in paper production. It is added to the paper pulp during the manufacturing process to increase the paper’s opacity, smoothness, and brightness. Talc particles fill the gaps between the fibers, resulting in a more even surface and improved printability
⦁ In paints, talc is an ideal, natural solution for replacing less environment-friendly TiO2 and for improving the mechanical and optical properties of coatings
⦁ In agriculture Talc make the effective flow and anti-caking agents for fertilizers and also it used as a carrier in insecticides
⦁ Used in ⦁ ceramic tiles and sanitary ware, talc improves the vitrification process, allowing producers to reduce firing temperatures and shorten firing cycles
⦁ largely used as a thickening agent and lubricant
