Soapstone Powder
RTC Talc is a metamorphic hydrated magnesium silicate with a soapy feel and pearly luster.
Its lamellar structure and the platy ness give excellent / opacity to the end products.
Composites filled with RTC
TALC enhances the performance properties of the compound. It exhibits higher stiffness, creep resistance at both ambient and
elevated temperature. It has a greasy feel.
Soapstone powder, Talc is the basic raw materialm for PP, LD, HDPE compounding,
paints industries, paper industries, rubber, pharmaceutical industry, PVC, cosmetic, baby talc manufacturing.

Application of Talc (Soapstone powder) in Plastic Industries
- Plastic Industry
consumes high quality ultra fine talc in polypropylene, polyamides, cable PVC 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 resistant. 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.
- Application of Talc in Paint Industries
Talc is used in production of decorative paints, industrial coatings,
pigment pastes, primers, enamels, adhesives, putties and other products of the industry.
- Application of Soapstone powder (Talc) in Ceramics
In ceramics talc is used mostly as low cost filler in ceramic
tiles, sanitary ware, dinnerware, porcelain and electrical insulating.
- Application of Talc Powder in Pharmaceutical Industries
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.
- Paper industry
Talc is used in three stages of paper making -as a filler, to control pitch and stickiest and
in paper coating. During the paper making process, the micro impurities can clog the paper machinery. Talc being hydrophobic
absorbs these micro droplets thus controlling their stickiness and avoiding clogging. High brightness of talc leads to reduction
in usage of expensive whitening agents and helps in controlling gloss of the coat. Talc gives smoothness, yellow index, porosity,
and opacity to paper, improves its yellow index and reduces the deterioration of the machinery. Our grades of Talc powder
are in wide range for Paper industries.
- Other uses of talc
Besides all above uses Talc is also widely used in Toilet Soap manufacturing, Cosmetic industries
in baby talc powder, Detergent manufacturing, Dal mills (Pulses polishing), Textile, Printing Ink, Rubber industry and as
a filler raw material in many chemical industries.
