Talc Powder / Magnesium Silicate

We offer quality Talc Powder that is a naturally occurring steatite. It is also called as French chalk & soap stone, and comes in brilliant white and off color. It has extremely soft soapy feeling and the powder is very slippery.

Following are some of its physical and chemical properties:

• SiO₂: 64.0 - 66.0%

• Fe₂O₃: 00.5%

• CaO: 1.5 - 2.5%

• Al₂O₃: 00.6%

Physical Properties

• Appearance: White fine smooth powder

• Sp. gravity: 2.7 to 2.9

• Bulk density: 0.5%

• Whiteness: 94%

• Oil absorption value: 35 to 40%

• Hardness: 1 (Mohs)

• Moisture & Volatile matter: 0.5% by wt. (105 deg. C)

• Water soluble matter: Max 0.5%

• pH of 10% aqueous solution: 8 to 10 (ASTM D 1208-65 BS 1795)

• Minimum 88% combined magnesium calcium silicate

Industrial Applications

• Paper: Gives smoothness, brightness to paper & partially replaces TiO₂. It also acts as pitch absorber

• Paints: Highly recommended for wood finishes, primers, putties, undercoated, architectural finishes, water based coatings. Its laminar structure helps in better corrosion protection and also improves exterior durability of paints. recommended for epoxy and exterior paints.

• Ceramics: Talc improves resistance to thermal shocks and gives superior electrical properties. It gives greater toughness to speak plugs and switch boards. It also improves dry pressing resistance of ceramic bodies.

• Foundries: Used in mould making and for final finish

• Plastic & Rubber: Used in variety of application as filler

• Cosmetics: Super fine talc powder is used in cosmetic for its smooth silky finish

Specifics

• Normal Supplies: 240/400/700 mesh, talc in both SSW and off white color or as per customer's demand

• Packing: HDPE bags. 50 Kg nett.

• Material Storage: Store the material in dry area. This material is non-hazardous & nonflammable.

• Shelf Life: The life span is upto 5 years

Note: The information provided is based on test report and reference. The user should test sample before bulk trial and is purely natural process minerals. So, there is possibility of purity ± 5%.
