Product whiteness: 94% - 95%- 96%

Calcium carbonate content:≥98%

Application field:mainly used in high-grade coatings, high-grade paints, inks, PVC, PE, PPR water supply and large sewage pipes, plastic steel profiles, polymer masterbatch, non-woven masterbatch, soft cable masterbatch, silicon copper adhesive, and breathable film.

Product Characteristics

Ultra - fine particle size: With a fineness of 3000 mesh, its particle size is extremely small, reaching the nanometer level, usually in the range of 1 - 100 nm. Such fine particles have a large specific surface area, which can enhance the interaction with the matrix material and improve the reinforcement effect.

High purity and whiteness: The calcium carbonate content is generally not less than 98.5%, and the impurity content is very low. It has high whiteness, usually over 96%, which is beneficial for improving the appearance quality and color stability of products, especially for light - colored or white products.

Good activity: Through surface activation treatment, the surface of the particles is covered with active substances, which significantly improve its lipophilicity and dispersibility in organic media. It can be evenly distributed in high - end application matrices, improving its compatibility with other substances and enhancing the interfacial bonding force.

Controllable particle shape: The particle shape of nanometer - grade calcium carbonate can be controlled, and common shapes include spindle - shaped, cubic, spherical, chain - like, needle - like, and flake - like. Different particle shapes have different effects in different applications.

For example, cubic calcium carbonate has good dispersibility and fluidity, while chain - like and needle - like calcium carbonates have excellent reinforcement effects.

Functions in High - End Applications

In the rubber industry: It can be used in the production of tires, hoses, belts, and other rubber products. It can improve the tensile strength, tear strength, and abrasion resistance of rubber products, enhance the hardness and modulus of rubber, and at the same time maintain good elasticity and flexibility. In the production of tires, it can be used in parts with less stress, such as the sidewall, cord rubber, air - tight layer rubber, inner layer rubber, and buffer rubber.

In the plastics industry: It is widely used in the processing of various plastics such as PVC, PS, and PP. It can increase the rigidity, hardness, and dimensional stability of plastic products, improve the heat - resistance, and reduce the thermal expansion coefficient, making plastic products more resistant to deformation under high - temperature conditions.

It can also improve the processing performance of plastics, making them easier to mix, extrude, and mold.

In the coating industry: It can improve the hiding power, gloss, transparency, drying speed, and stability of coatings. In some industries such as automotive coatings and architectural coatings, it can partially or completely replace titanium dioxide, which is expensive, to reduce costs.

Adding it to organic or water - based coatings can make the formed coating have the characteristics of being fine, uniform, quick - drying, and having high whiteness.

In the ink industry: The modified nanometer - grade calcium carbonate has good compatibility with the binder and has the advantages of high gloss, strong stability, good adaptability, and excellent drying performance.

It can comprehensively improve the quality of ink and reduce production costs. The nanometer - grade calcium carbonate used in ink has high requirements for performance.

After use, the ink should have good dispersibility, absorbability, transparency, gloss, and good hiding power and printing adaptability.

In the adhesive and sealant industry: It has good compatibility with adhesives and sealants, can accelerate the cross - linking reaction of glue, improve thixotropy, and enhance the bonding strength and reinforcement effect. It is widely used in silicone rubber, MS rubber, polyurethane rubber, and other sealants.

Product Advantages

Wide range of applications: It is suitable for various high - end applications in rubber, plastics, coatings, inks, adhesives, and sealants, and can meet the performance requirements of different products in different fields.

High performance - to - price ratio: 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 products.

Stable quality: With strict quality control, the physical and chemical properties of water - milled heavy - active ultrafine nanometer calcium carbonate 3000 mesh are relatively stable, which can ensure the consistency of product performance during production.
