Heavy Active Calcium Carbonate 600 Mesh - Fine Powder Calcium Carbonate for Rubber and Plastics

Features:

High chemical purity, not easy to chemical reaction, good thermal stability, stable color, low oil absorption value, high whiteness, uniform particle size distribution, non-toxic, odorless, odorless, good dispersion and other characteristics.

Product Characteristics

Particle Size and Morphology

With a 600 mesh fineness, the calcium carbonate particles are relatively fine. They have a certain degree of uniformity in size, and their shape can vary from irregular to somewhat spherical in some cases.

This fine particle size allows for better dispersion within rubber and plastic matrices, enhancing the overall performance of the final products.

High Purity
The product typically has a high calcium carbonate content, often exceeding 95%. Impurities such as iron, manganese, and other trace elements are present in very low amounts.

High purity ensures that the calcium carbonate does not cause adverse chemical reactions in rubber and plastic compounds, maintaining the stability and quality of the materials.

Surface Activity
The surface of the calcium carbonate particles is activated through processes like treatment with stearic acid or silane coupling agents.

This activation makes the particles more lipophilic, enabling them to interact effectively with rubber and plastic polymers. As a result, the filler can be evenly distributed, improving the compatibility between the calcium carbonate and the matrix materials.

Functions in Rubber and Plastics

Reinforcement in Rubber

In the rubber industry, heavy active calcium carbonate acts as a reinforcing filler. It improves the mechanical properties of rubber compounds, such as tensile strength, tear strength, and abrasion resistance. For example, in the production of tires, the addition of this calcium carbonate can enhance the durability of the rubber, making the tires more resistant to wear and tear.

Enhancing Plastic Properties
In plastics, the calcium carbonate filler can increase the hardness, stiffness, and dimensional stability of plastic products. It also helps to reduce the shrinkage during the molding process, ensuring that the plastic parts maintain their shape and size.

Additionally, it can improve the heat resistance of plastics, making them suitable for applications where exposure to high temperatures is expected.

Cost Reduction

As a filler, heavy active calcium carbonate can partially replace more expensive rubber or plastic raw materials. By adjusting the formulation and adding an appropriate amount of calcium carbonate, manufacturers can reduce production costs without sacrificing too much of the product's performance. This cost-effectiveness is particularly important in industries where cost control is crucial.

Improving Processing Performance

The surface activation of the calcium carbonate particles improves the fluidity of rubber and plastic compounds during processing. It reduces the viscosity of the mixture, making it easier to mold, extrude, or inject. This improved processing performance can increase production efficiency and reduce energy consumption.

Product Advantages

Cost-Effectiveness

As mentioned, the ability to replace more expensive materials while maintaining or even enhancing certain properties makes heavy active calcium carbonate a cost-effective option for rubber and plastic manufacturers. It allows for cost savings without significant performance degradation.

Wide Applicability
It is suitable for a wide range of rubber and plastic products, including tires, rubber hoses, plastic pipes, and injection-molded parts. Its versatility makes it a popular choice in various industries, from automotive to construction.

Stable Quality

With strict quality control measures, the physical and chemical properties of heavy active calcium carbonate 600 mesh are relatively stable. This stability ensures consistent performance in rubber and plastic production, reducing the variability of the final products.

Enhanced Performance
The reinforcement and property enhancement functions of this calcium carbonate contribute to the overall performance of rubber and plastic products. It can meet the requirements of different applications, such as high mechanical strength in industrial rubber products or good dimensional stability in plastic components.

Application:plastic, rubber, paper, paint, paint, cable, building materials and other industries.
