Talc is the world's softest mineral. Although all talc ores are soft, platy, water repellent and chemically inert, no two talcs are quite the same. Talc is a vital part of everyday life.
Talc or talcum is a clay mineral composed of hydrated magnesium silicate with the chemical formula H 2 Mg 3 (SiO 3) 4 or Mg 3 Si 4 O 10 (OH) 2. In loose form, it is (in ratio with or without corn starch ) one of the most widely used substances known as baby powder .
2.1 Talc mineral filler Talc is a phyllosilicate mineral with a tri-octahedral layered structure, Mg 3 Si 4 O 10 (OH) 2. The idealized crystal structure contains a layered structure
Our product range includes Micronized Calcium Carbonate, Precipitated Calcium Carbonate, Talc Powder, Wollastonite Mineral, Crystalline Feldspar Powder, China Clay and Quartz Silica Powder.

TALC is also written as H2Mg3(SiO3)4, which corresponds to 4.8% H2O; 31.7% MgO and 63.5% SiO2 It is essentially a secondary mineral formed by the hydrothermal actions and regional metamorphism of magnesium rich rocks like dolomite, pyroxenite, amphibolite, serpentine, dunite and chlorite
Talc mineral acts an extender and effective filler in paints. This is attributed to its platy-shaped particles that enhance the solids' suspension inside the can of paint and this aids the liquid paint to adhere to the wall without sagging.
Talc. The term talc covers a wide range of natural rocks and minerals, most of which are magnesium silicates. The pure talc mineral is a hydrous magnesium silicate, Mg3Si3O10(OH)2, which theoretically is 31.7 percent MgO, 63.5 percent SiO2, and 4.8 percent H2O.

Calcium carbonate (CaCO 3) and talc are two widely used mineral fillers in the plastics industry, and their use in rigid packaging has increased significantly over the years. Once thought of simply as resin extenders, the addition of these mineral fillers to materials such as polypropylene, has been shown to contribute to increased performance, improved processing, and improved sustainability ...
A white, greenish, or gray mineral that is a silicate of magnesium, usually occurring as massive mica-like flakes. It has a soft, soapy texture, and is used in face powder and talcum powder, for coating paper, and as a filler in paints and plastics.
The most commonly used particulate fillers are industrial minerals such as silica, talc, calcium carbonate, mica, kaolin, wollastonite, feldspar and barytes. The choice of filler used in a specific application depends on the physical attributes of the mineral.
Talc is the softest mineral filler used in the plastics industry. It has high resistivity, low gas permeability, low abrasiveness, and high lubricity. All of these qualities are attributed to talc's platey structure. The aspect ratio of talc fillers is as high as 20:1.

Hardness values of fillers range from 1.0 for talc to 7.0 for silica on the Mohs scale. Abrasiveness, a function of hardness, is particularly high in silica-filled composites.
Talc is a soft, non-abrasive inert mineral powder that acts as a functional filler in paint, thermoplastics, rubber and adhesives. Its flaky or plate-like structure provides structural strength or reinforcement, heat resistance, pigmentation, opacity, rheology and corrosion and weather resistance in a …
Talc is harmless to our skin and is inert making it the ideal mineral to put in detergents as filler. Body soap is sometimes made of Talc. It acts as filler and does not hurt the skin.
In Pharmaceuticals and cosmetics talc's greasy feel [lubricant or glident], fragrance retention [talcum powder, soaps, creams, and lotions] and hiding powder are useful characteristics. In roofing products, talc acts as a stabilizer for the melted asphalt thus increasing resistance to fire and weathering.
Talcum powder is made from the mineral talc, which is an ingredient in a wide variety of products we use each and every day. When talc is crushed into a powder, it can absorb moisture, oils and odor, making it popular for use in bath and body products.
Working with polypropylene sheet for the first time often presents new challenges for thermoformers including shrinkage, low rigidity, and low stiffness. The addition talc or calcium carbonate mineral fillers can help remedy these problems while contributing added benefits compared to resin-only formulations.
Talc Talc is the softest mineral, demonstrated by its position at the bottom of Mohs' Scale of Hardness with a relative hardness value of 1. It has a soapy, greasy feel. Talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites.
Golcha Talc is the leading talc producers, soapstone producers in India. Our Mineral products are absolutely free from any types of bi-minerals like silica and
What and Why of Mineral Fillers Mineral filler is ground up rock/mineral added to a mix: Therefore, mineral filler is an additive and modifier, not the main product.
