Guibao Brand Calcium Carbonate 1250 Mesh - High-Quality Calcium Carbonate for Polymer Manufacturing

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, the calcium carbonate content is over 99%, with extremely low impurity content. This ensures that it has minimal impact on the performance of polymers, helping to maintain the stability of polymer product quality.

Fine Particle Size: The 1250 - mesh particle size indicates that the particles are very fine, which is beneficial for uniform dispersion in polymers. It can fill the microscopic gaps in polymers, improve the surface smoothness of polymer products, and enhance their appearance quality.

Good Whiteness: It has a high whiteness, generally not less than 95%. The high - whiteness calcium carbonate can enhance the whiteness and hiding power of polymer products, which is particularly important for some light - colored or transparent polymer products, improving their decorative and covering effects.

Low Oil Absorption Value: It has a relatively low oil absorption value, which helps to reduce the amount of additives such as plasticizers in polymer manufacturing. This can not only reduce production costs but also improve some properties of polymers, such as reducing the viscosity of polymer melts and improving processing performance.

Good Chemical Stability: It has excellent chemical stability and is not easily affected by chemical substances. It can maintain stable performance in different chemical environments, which is beneficial for the long - term use of polymer products in various application scenarios and is not prone to chemical reactions that affect the performance of polymers.

Functions in Polymer Manufacturing

Reducing Costs: As a filler, it can replace some expensive polymer resins, thereby reducing production costs. Under the premise of meeting the basic performance requirements of polymers, the appropriate addition of Guibao Brand Calcium Carbonate 1250 Mesh can effectively control production costs and improve the economic benefits of polymer products.

Improving Mechanical Properties: It can improve the hardness, rigidity, and dimensional stability of polymers. Appropriate addition can increase the mechanical strength of polymers, making them more resistant to deformation and wear, and prolonging the service life of polymer products.

For example, in the production of plastic pipes, the addition of calcium carbonate can improve the pressure resistance and impact resistance of the pipes.

Enhancing Processing Performance: The fine - particle - sized calcium carbonate can improve the fluidity of polymer melts, making the processing and molding of polymers easier and improving production efficiency.

At the same time, it can also reduce the shrinkage and warping of polymer products during cooling and solidification, improving the dimensional accuracy of products.

Improving Optical Properties: The high - whiteness and good hiding power of calcium carbonate can improve the whiteness and transparency of polymer products, meeting different aesthetic requirements. For example, in the production of white plastic products or transparent plastic films, the addition of calcium carbonate can improve their visual effects.

Product Advantages

Wide Range of Applications: It is suitable for various types of polymers, including polyethylene, polypropylene, polyvinyl chloride, and polyester. It can meet the performance requirements of different polymer products in different fields, such as in the production of plastic products, rubber products, and fiber - reinforced composites.

Stable Quality: With strict quality control, the physical and chemical properties of Guibao Brand Calcium Carbonate 1250 Mesh are relatively stable. This ensures the consistency of polymer product performance during production, reduces product quality fluctuations caused by raw material differences, and is conducive to manufacturers' large - scale production and quality control.

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 improve the market competitiveness of polymer products.
