Ultrafine Heavy Active Calcium Carbonate 2800 Mesh - Ultra-Fine Active Calcium Carbonate for Rubber and Plastics
Product Characteristics
Extremely fine particle size: With a fineness of 2800 mesh, its particle size is extremely small, and the D50 particle size can be controlled at about 1 - 2 μm.
Such fine particles can provide a large specific surface area, which helps to improve the contact area and interaction between calcium carbonate and rubber or plastic matrices, and enhance the reinforcement effect.
High purity and whiteness: The calcium carbonate content is usually not less than 98.5%, and the impurity content is very low.
It has high whiteness, generally reaching over 96%, which has a positive effect on improving the appearance quality and color stability of rubber and plastic 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 such as rubber and plastics.
It can be evenly distributed in the matrix, improving its compatibility with rubber and plastic molecules and enhancing the interfacial bonding force.
Appropriate oil absorption value: The oil absorption value is generally in the range of 30 - 40 g/100 g. This oil absorption value enables it to absorb an appropriate amount of rubber - processing oil or plasticizer in rubber and plastics, which helps to adjust the viscosity, fluidity, and softening properties of rubber and plastics, and is beneficial to the processing and molding of products.
Functions in Rubber and Plastics
Improving mechanical properties: In rubber, 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 plastics, 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.
Enhancing processing performance: Due to its good dispersibility and fluidity, Ultrafine Heavy Active Calcium Carbonate 2800 Mesh can make rubber and plastics easier to process during mixing, extrusion, and molding.
It can reduce the viscosity of the mixture, improve the fluidity, and make the processing more smooth, which is beneficial to improving production efficiency and reducing energy consumption.
Reducing production costs: As a filler, it can replace some expensive rubber or plastic raw materials to a certain extent while ensuring the performance of rubber and plastic products, thereby reducing the production cost of products. And because of its high filling amount, the cost - reduction effect is more obvious.
Improving surface quality: It can improve the surface smoothness and gloss of rubber and plastic products, reduce surface defects and roughness, and enhance the appearance quality and market competitiveness of products.
Product Advantages
Wide range of applications: It is suitable for various types of rubber and plastics, such as natural rubber, synthetic rubber, polyethylene, polypropylene, polyvinyl chloride, etc., and 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 2800 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 rubber and plastic products manufacturers.
Application fields: mainly used in coatings, paints, sealants, plastics, rubber and daily chemical industries.
