Soapstone (also known as steatite or soaprock) is a
metamorphic rock, a talc-schist. It is largely composed of the
mineral talc and is rich in magnesium. It is produced by dynamo
thermal metamorphism, which occurs at the areas where tectonic
plates are subducted, changing rocks by heat and pressure, with
influx of fluids, but without melting. It has been a medium for
carving for thousands of years.
Advantages for Polymer
Advantages for Paints
• Good surface quality.
• Easier processing.
• Maximum Loading.
• Excellent scrub resistance.
• Good coverage.
• Higher loading.
• Water resistance.
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
In ceramics talc is used mostly as low cost filler in ceramic
tiles, sanitary ware, dinnerware, porcelain and electrical
Application of Talc Powder in Pharmaceutical
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.
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.
Our grades of Soapstone powder (Talc) is available from 300
mesh to 700 mesh BSS Standard. The brightness in Talc is
available from 70% to 99%.
