Talc is Magnesium-Silicate-Hydrate with extremely lamellar structure having high aspect ratio. Because of the platy nature of this special form of talc, it is considered a RENIFORCING FILLER in many plastic application.
WHY USE OUR TALC
We take utmost care in the selection of soap stone lumps. Only white colored assorted lumps are used to ensure freedom from impurities.
The micronization and classification further render the material highly suitable for application where ultrafine size high purity is required. |

FEATURES |
| |
The main characteristics of talc that make it a unique material for industrial and domestic application are:
|
Lamellanity |
|
Softness |
|
Chemical Inertness |
|
Affinity For Organic Chemical |
|
Whiteness |
The main technical function talc is used are anti-sticking,anti –caking ,lubricant,carrier,thickener, strengthening filler,smooth filler and absorbent. |

Application |
| |
| |
|
|
Plastic Industry |
| |
Plastic Industry consumes high quality ultra fine talc in automotive (bumpers, dashboards, interior trims etc.) and aesthetic (computer and TV bodies, garden furniture etc.) Polypropylene, polyamides, cables PVCs and other plastic compounds. Talc is being increasingly used in HDPE, PP, LDPE, PVC, ABS & thermosetting compounds. It is excellent filler due to blending characteristics and thermal and electrical resistance. It is chemically inert. It provides the smooth feel to plastic surface. Due to its chemical inertness, superior electrical and thermal resistance and other properties talc imparts stiffness, hardness, tensile strength of plastic products, improves quality of their surfaces, gives them electrical, chemical and thermal resistance. |

|
|
Paint Industry |
| |
In paint industry talc is used in production of decorative paints, industrial coating, pigment pastes, primers, enamels, adhesives, putties and other products of the industry. Due to natural properties of paint, imparts corrosion, acid, thermal, air resistance to them, increase smoothness and stability of paint products. |
| |
|
|
Ceramics |
| |
In Ceramics talc is used mostly as a cheap filler in ceramic tiles, sanitary ware, dinnerware, porcelain and electrical insulating. |
| |
|
|
Paper Industry |
| |
In paper industry talc is used in three stages of paper making – as a filler, to control pitch and stickies and in paper coating. During the paper making process, the micro impurities can clog the paper machinery. Talc being hydrophobic absorbs theses micro droplets thus controlling their reduction in usage of expensive whitening agents and helps and helps in controlling gloss of the coat. Talc gives smoothness, yellow index, porosity, opacity to paper, improves its yellow index and reduces the deterioration of the machinery. |

|
|
Cosmetics |
| |
In cosmetics talc is used as a body talc and as filler in some cosmetic products – toothpaste, soap, detergents etc. Talc imparts stability, texture, water resistance and skin adhesion to cosmetics. In body talc it acts as a perfume carrier due to its chemical inertness lamellar structure. |
| |
|
|
Pharamaceuticals |
| |
In pharmaceuticals talc is used as filler in tablets, ointments and dustings. Talc used in this industry must be highly pure, bacteria free, must contain no iron oxide, dolomite, carbon and other impurities. |
