Guibao Brand Calcium Carbonate 400mesh - Fine Calcium Carbonate for Plastics and Coatings

Calcium carbonate is a non-toxic, tasteless, non-irritating white powder, one of the most versatile inorganic fillers. It is dry and does not contain crystallized water, and is exposed to the air.

Almost insoluble in water, insoluble in alcohol, dilute acetic acid, dilute hydrochloric acid, dilute nitric acid to boil and dissolve;Heat is decomposed into calcium oxide and carbon dioxide.

Calcium carbonate has not only cheap, abundant resources, high grade, etc, but also has some properties of fllers, widely used in coatings, plastics, printing ink, putty, plastic flm, chemical fiber, sealants, adhesives, daily-used chemical industry, medicine, rubber, paper, toothpaste, cosmetics, food, textile, building materials, fodder, etc.

Product Characteristics

High Purity: Usually, it has a high calcium carbonate content, which can reach over 99%. With less impurity, it has little impact on the performance of plastics and coatings, ensuring the stability of product quality.

Fine Particle Size: The 400 - mesh particle size indicates that the particles are relatively fine, with a D50 particle size of about 15 μm. Such fine particles can be uniformly dispersed in plastics and coatings, improving the smoothness and appearance quality of products.

Good Whiteness: It has a high whiteness, generally not less than 96%. The high - whiteness calcium carbonate can enhance the color brightness and hiding power of coatings, and also improve the whiteness of plastic products, meeting different color requirements.

Excellent Thermal and Chemical Stability: It has good thermal and chemical stability. It can maintain stable performance within a certain temperature range and is not easily affected by chemical substances, which is beneficial to the processing and use of plastics and coatings in different environments.

Applications and Functions

In Plastics
Reducing Costs: As a filler, it can significantly reduce the cost of plastic products because the price of calcium carbonate is relatively low compared to plastic resins.

Improving Performance: It helps improve the hardness, rigidity, and dimensional stability of plastics. Appropriate addition can also enhance the heat resistance of plastics to a certain extent.

Enhancing Processability: It can improve the fluidity of plastics during processing, reduce the friction between the material and the mold, and prolong the service life of the mold.

In Coatings

Adjusting Coating Properties: It is used as a filler to improve the thickness, hardness, and wear resistance of the coating film. It can also enhance the adhesion of the coating to the substrate.

Reducing Costs: The addition of calcium carbonate can reduce the amount of expensive film - forming substances in coatings, thereby reducing production costs without significantly affecting the performance of the coatings.

Improving Optical Properties: It can improve the whiteness and hiding power of coatings, making the coating have better decorative and covering effects.

Product Advantages

Wide Range of Applications: It is suitable for various plastic and coating products, including general - purpose plastics, engineering plastics, architectural coatings, industrial coatings, etc., meeting the needs of different products in different fields.

Stable Quality: With strict quality control, the physical and chemical properties of Guibao Brand Calcium Carbonate 400 - mesh are relatively stable, ensuring the consistency of product performance and facilitating large - scale production and quality control for manufacturers.

Cost - Effective: While ensuring product performance, it has a relatively reasonable price, which helps manufacturers improve product competitiveness.

Application:

Coating, Plastic, Rubber, Papermaking
