Micronised and coted calcite must contain of high purity and must not contain of heavy metals which are spoiling polymers. It must be supply; easy dispersion, lack of absorption of the chemicals which are used at formulation, economical benefits by decreasing of other expensive white pigments, hydrophobic structure, lack of abrasion at machines, easy homogeneous dispersion. In addition to this, increasing of; hardness, stability, surfacequality of the final product and resisting against stroke. However it has not contain of any smell, taste and toxic matters.

One of the main ways of the decreasing of the expenses is using coated calcite at process. Calcite as an inorganic matters like polymers must be coated. Thus it has not surface strain difference. 

 Those benefits are depend upon the high coating quality of the calcite. As Hisar products have been coated with stearic acid, getting maximum coating technology unite, has taken a prodigious step in to plastic sector as well.

Hisar’s coated products (Hisarcal ST) have proved themselves in the plastic industry with high coating rate by unique stearic acit coating technology.

Coated Calcite Provides Plastic to have:

• Hydrophobic Structure
• Low Surface Energy
• Easy Dispersion
• High Homogenization
• Increase in Resistance
• Chemical Durability
• Adaptation to Organic Environments
• Brighter and Smoother Surface
• Less Mould Abrasion
• Increase in Machine Productivity

Follow the simple method below to define calcite’s the coated rate:

Add 2-3 teaspoon of coated calcite on half tea glass of water. Cover the glass completely with your palm and shake it a few times. Insufficiently coated calcite will change the color of water.
