Calcium Carbonate

Calcium Carbonate produced by grinding Calcite (sand size) into powder. Calcite is also the most stable among the rock-forming minerals with CaCO3 structure. It is glassy luster, transparent to translucent, white or colorless.

 

The Company produces two types of calcium carbonate production which are coated and uncoated form, approximately 1.5 to 4.0 microns. The uncoated calcium carbonate is processed by grinding calcite (sand size) and screening the specific size, then packing for sale. For the coated calcium carbonate, it is processed by grinding calcite (sand size) and coating with stearic acid, then packing for sale. Calcium carbonate can be used in various industries such as a filler and extender in paint, rubber, plastic, PVC, paper industries, or used as an ingredient in toothpaste, detergents, drugs, unshielded telephone cable, insulated wire, pen, eraser, gloves, glasses among others. It is distributed domestically and internationally under the registered Rhinoceros trademark. Calcium Carbonate product from SUTHA branded as ‘Rhinoceros’ has passed the certification by the product standard consist of:

COATED

Calcium Carbonate (COATED)

UNCOATED

Calcium Carbonate (UNCOATED)

The product from Calcium Carbonate has passed the
certification by the product standard consist of

Quality Management, Environmental Management Systems and Occupation & Health and Safety Management system for Lime and Calcium Carbonate Production

Standard certification for products manufactured and packaged for distribution to consumers in accordance with the conditions for requesting halal reception.

Calcium Carbonate Powder

Calcium Carbonate Powder Calcium Carbonate Powder produced by TMC (subsidiary) is the rock-forming minerals with CaCO3 structure. It is produced by the marble fragments with different mineral characteristics from Calcite used to produce coated and un-coated Calcium Carbonate power in purity, whiteness and moisture. Calcium carbonate powder is a product from the marble quarry operation and it is a by-product from the marble slab production process that has been grounded by a special process from the factory and filtered into powder until achieving the desired size. Because the customers who are using Calcium Carbonate powder are in different groups of industries, therefore, there is no competition for this product market between the Company and subsidiary.

Industry Usage
Pipe and PVC

Uses as a filler to improve the following plastic properties

  • Sheen and shine
  • Improves rubber
  • Compression force resistance
  • Shrinkage
  • Temperature and humidity resistance
Pulp & Paper
  • Increases pulp opacity
  • Enhances pulp consistency and homogeneity
  • Improves printing and ink-absorbing properties of paper
  • Enhances pulp and paper structure by filling in the spaces inside it
  • Improves water-draining property, essential during the production process
  • Reduces needed energy to dry paper because it holds less water since calcium carbonate takes up space inside it
