Ultrafine Heavy Active Calcium Carbonate 800 Mesh - Fine and Active Calcium Carbonate for Inks and Plastics

Product Characteristics
Particle Size and Surface Activity: With a fineness of 800 mesh, it has relatively fine particles, and after surface activation treatment, it has good lipophilicity.

The active substances on the particle surface can improve its dispersion in organic media such as inks and plastics, and enhance its affinity with resins.

High Purity and Whiteness: Usually, the calcium carbonate content is not less than 98%, and the impurity content is extremely low. It has high whiteness, generally reaching over 96%, which is beneficial for improving the color purity, hiding power, and decorative effect of inks and plastics.

Proper Oil Absorption Value: The oil absorption value is generally around 30 - 40 g / 100 g. This oil absorption value enables it to absorb an appropriate amount of resin and additives in inks and plastics, which helps to adjust the fluidity, drying properties, and film - forming properties of inks, and also has a positive impact on the processing and performance of plastics.

Good Chemical Stability: It has excellent chemical stability, is not easily affected by general chemical substances, and can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of inks and plastics.

Functions in Inks and Plastics
In Inks
Improving Printing Quality: It can improve the dispersion of pigments in inks, making the color of inks more uniform and stable. Due to its high whiteness and proper particle size, it can enhance the hiding power and gloss of inks, improve the clarity and definition of printed patterns, and make the printed matter have better visual effects.

Adjusting Ink Properties: It helps to adjust the viscosity, fluidity, and drying speed of inks. The appropriate oil absorption value allows inks to absorb an appropriate amount of binder, improving the adhesion of inks to the printing substrate, and at the same time, ensuring the quick - drying property of inks, which is beneficial to improving the printing efficiency.

In Plastics
Enhancing Mechanical Properties: It can improve the hardness, stiffness, and tensile strength of plastics to a certain extent. The active treatment enables better combination between calcium carbonate and the plastic matrix, enhancing the internal structure of plastics and improving their resistance to deformation and damage.

Improving Processing Performance: It can improve the fluidity of plastics during processing, reduce the friction between plastics and the processing equipment, and thus reduce the wear of the mold. In addition, it can also shorten the kneading time during processing, improve production efficiency, and is beneficial for the molding and processing of plastics.

Reducing Costs: As a filler, it can replace part of the resin, thereby reducing the amount of resin used and effectively controlling production costs under the premise of meeting the performance requirements of plastics.
Product Advantages

Wide Range of Applications: It is suitable for various types of inks, such as offset inks, gravure inks, and flexographic inks, as well as various plastics, including polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP). It can meet the performance requirements of different products in different fields.

Stable Quality: With strict quality control, the physical and chemical properties of Ultrafine Heavy Active Calcium Carbonate 800 Mesh are relatively stable.

This ensures the consistency of product performance during production, reduces product quality fluctuations caused by raw material differences, and is conducive to the large - scale production and quality control of manufacturers.

Cost - Effective: While ensuring product performance, it has a relatively reasonable price. Compared with some high - performance fillers, it has a certain price advantage, which can help manufacturers reduce production costs and improve the market competitiveness of ink and plastic products.

Application fields: mainly used in coatings, paints, sealants, plastics, rubber and daily chemical industries.
