Ultrafine Heavy Active Calcium Carbonate 600 Mesh - Active Calcium Carbonate for High-End Paints and Plastics
Product Characteristics
Particle Size and Dispersion: With a fineness of 600 mesh, its average particle size is relatively coarse among ultrafine calcium carbonates, but it still has good dispersibility.
The particle surface is covered with active substances, which makes it more easily dispersed in organic substances than ordinary heavy or light calcium carbonates that have not been activated, and has better lipophilicity, being able to be fully miscible in organic materials.
High Purity and Whiteness: The calcium carbonate content is generally not less than 98%, and the impurity content is extremely low. It has excellent whiteness, usually reaching over 97.0%, which can improve the hiding power and decorative effect of coatings and the color stability of plastics.
Proper Oil Absorption Value: The oil absorption value is generally ≤ 28 g / 100 g. This oil absorption value is beneficial for the formulation design of high - end paints and plastics. It can absorb an appropriate amount of resin and additives, helping to improve the fluidity, drying properties, and film - forming properties of paints, and also has a positive effect on the processing and performance of plastics.
Good Chemical Stability: It has excellent chemical stability and is not easily affected by general chemical substances. It can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of high - end paints and plastics and is not prone to chemical reactions that affect quality.
Functions in High - End Paints and Plastics
In High - End Paints
Improving Film - Forming Properties: As a filler, it can increase the thickness and volume of the coating film, improve the filling performance of the coating, and make the coating film more compact.
It can fill the pores and uneven surfaces of the substrate, improve the flatness of the coating film, and enhance the decorative effect. At the same time, it can improve the adhesion, hardness, and wear resistance of the coating film.
Enhancing Color Performance: The high - whiteness and proper particle size of ultrafine heavy active calcium carbonate can improve the hiding power of coatings, covering the color and texture of the substrate.
It can also improve the color stability and uniformity of coatings, making the colors more vivid and durable. In some light - colored or white coatings, it can be used as a main pigment extender to reduce the use of expensive pigments and thus reduce production costs.
In High - End Plastics
Reducing Costs: It can be used as a filler to reduce the amount of resin used, thereby reducing production costs. Under the premise of meeting the performance requirements of plastics, appropriately increasing the amount of calcium carbonate added can effectively control production costs.
Improving Mechanical Properties: To a certain extent, it can improve the hardness, whiteness, and bending properties of plastics. The active treatment makes the calcium carbonate better combined with the plastic matrix, which helps to improve the overall mechanical properties of plastics.
Product Advantages
Wide Range of Applications: It is suitable for various types of high - end paints and plastics, such as automotive paints, architectural coatings, engineering plastics, and general - purpose plastics, which 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 600 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 high - end paint and plastic products.
Application fields: mainly used in coatings, paints, sealants, plastics, rubber and daily chemical industries.
