We are manufacturers of Micro-minerals like Talc / Soapstone which is used in making soap & detergents and Talcum Powder. Talc is a versatile mineral, widely used in various industrial applications. The nature of deposit, formation of talc is the index of its chemical purity, particle shape and other physical features. Talc possesses some unique and unusual properties, which makes it ideal for its multiple uses. No other mineral other than talc possesses such combination of intrinsic properties. Mainly there are three types of structures in the talc Platy, Acicular and Granular. Minerals commonly associated with some commercial talc in significant amounts include the Carbonates, Calcite, Dolomite, Magnesite & other Silicates, Anthophyllite, Chlorite, Quartz, Serpentine and Tremolites. Serpentine and Tremolites are hazardous impurities possessing ACICULAR structure.  The deposits located in the north of Rajasthan, are in massive form of the talc, primarily with the Platy particle shape with high chemical purity and reflectance values. They are non-abrasive and free from ASBESTOS and BIMINERALS, especially grits etc. The important properties of Talc are its chemical inertness, high dielectric strength, high thermal conductivity, low electrical conductivity and Oil & Grease absorption.  

Dolomite is a natural form of calcium magnesium carbonate with a high degree of whiteness. It is also noted for its remarkable wettability and dispersibility as well as its moderate oil and plasticiser absorption. Apart from the above mentioned advantages, Dolomite is a fine homogeneous product without any agglomeration. Distinct Features : High Specific Gravity High Bulk Density Less Reactive Applications: Plastics Paints Other Thermoplastics Polyester Glass fibre reinforcements Ceramics Powder Coating.

Calcite is a natural form of calcium carbonate widely used in Plastics, Paints and Rubber as a filter due to its high dispersibility, low oil absorption, higher impact strength, smooth surface finish, easy processing and excellent dimensional stability. Effects on properties of polymers : Increase in flexuaral modules Increase in dimensional stability reduces creep resistance Increase in HDT Lower melt viscosity Improved electrical properties Improved processing characteristics Good dispersion Excellent hiding power.Recommended Applications : PP compounding for furnitures, automobiles and home appliances Antifabrilliant Masterbatches for PP and LDPE woven sack Colour Masterbatches and other additive Masterbatches PVC Cable compounding Paints Paper Coatings Thermoset plastic Vinyl floorings PU foam (Flexible and Rigid) Powder Coatings.
