Activated Calcium Carbonate

model Activated CaCO3

Product Description

Activated calcium carbonate obtained by chemically treating ground calcium carbonate has better dispersion, reinforcement, and electrical insulation properties compared to untreated heavy calcium carbonate. For rubber and plastic products, it imparts high tear resistance and improved resistance to bending cracking. In industrial applications, it provides good flowability or extrudability during processing and enhances resistance to tearing and flexural cracking of the products.

Product Details

Specification

Raw Materials Used

Natural Limestone Lump

Process Overview

Natural ground calcium carbonate is crushed into calcium carbonate (CaCO₃) powder through mechanical grinding.
The resulting calcium carbonate undergoes chemical surface treatment to become activated calcium carbonate.
After fine grading, the product is packaged as modified calcium carbonate (chemically treated ground calcium carbonate).

Product Features

Surface-modified calcium carbonate.
Low oil absorption.
Good particle flowability.
Improved dispersion and reinforcement effects.
Hydrophobic, does not readily absorb moisture, enhancing electrical insulation.
Can be selected based on requirements such as fineness, bulk density, specific surface area, and color (whiteness).

Applications

Used in industrial products like plastics: Acts as a pollution-free reinforcing filler suitable for producing white or transparent products. It offers excellent aging resistance, insulation, scratch resistance, and minimal discoloration upon folding. It provides outstanding reinforcement, enhancing tear and flexural resistance.
Used in paint and coating products: Printing inks, synthetic resin coatings, glazes, oil-based paints, latex paints, primers, and white line coatings.
Used in agriculture and livestock industry: Soil improvement, crop protection agents, etc.
Used in consumer goods: environmentally friendly garbage bags, etc.

Packaging
