Physical Properties and Performance

The ability of calcium carbonate particles to disperse uniformly within a medium is essential for ensuring product quality stability and enhanced performance. In paints, this provides excellent coloring and smoothness, while in plastics and sealants, it ensures uniform physical properties. As demands grow for high functionality and the application to fine components, this property is a key factor in maintaining consistent productivity and quality.

Calcium carbonate with high-modulus characteristics imparts excellent rigidity and strength to products. Especially, in sealants and adhesives, it delivers a high elastic modulus after curing and ensures high durability while supporting structural deformation. It plays an important role in stabilizing products and extending their service life in applications such as automotive weight reduction process and production of structural components for electronic devices, ensuring reliability under demanding conditions.

Calcium carbonate with low-modulus characteristics adds excellent flexibility and high conformability to products. In sealants, this allows the material to flexibly follow the movement of substrates, preventing cracking and peeling, ensuring long-term waterproof and airtight performance. It contributes to enhanced durability and reliability in applications subject to deformation or expansion and contraction, such as building joints, bonds between dissimilar materials, and flexible electronic devices.

Through advanced particle control technology, our high-viscosity calcium carbonate appropriately regulates the flow of liquid materials, contributing to thick film formation and stable application on vertical surfaces, particularly in sealants and plastisols. Its ability to prevent dripping and to reliably hold a desired shape adds significant value in high-precision construction and the development of advanced surface treatment materials in the automotive and construction sectors.

Calcium carbonate with low-viscosity characteristics provides excellent processability without compromising flowability, even when highly loaded into resins or paints. This reduces energy consumption during molding while improving production efficiency. It is a foundational material for plastic products and sealants aiming to reduce material costs through high loading and to achieve specific performance properties.

Calcium carbonate with high elongation enhances the ability of materials to undergo significant deformation without breaking. In sealants and rubber products, this property allows flexible response to component movement and thermal expansion or contraction, suppressing cracks and fatigue failure. It contributes to product life extension in fields requiring high durability and long-term reliability, such as building joints and automotive interiors and exteriors.

Calcium carbonate with high-strength properties improves the mechanical characteristics of products and enhances resistance to external stress. In sealants, plastics, and rubber products, it improves tensile and compressive strength, significantly enhancing durability and reliability. It is an essential material to secure structural reliability, such as automotive part safety, earthquake resistance of building materials, and the robustness of electronic devices.

Highly thixotropic calcium carbonate exhibits a temporary decrease in viscosity under shear stress and returns to its original high viscosity once the stress is removed. This improves the application workability of sealants and paints and effectively prevents dripping or slipping on vertical surfaces. It contributes to quality improvement in fields requiring high-precision and efficient application, such as automotive assembly and exterior wall painting in construction.

Hydrophobic calcium carbonate imparts water-repellent properties to material surfaces and inhibits moisture penetration. This enhances product life and reliability across a wide range of applications, including improved coating durability, rust prevention for metal components, and moisture protection for electronic parts. It is gaining attention as an important functional filler that improves durability and corrosion resistance, particularly in products intended for outdoor or high-humidity environments.

Calcium carbonate with excellent weather resistance enhances the ability of products to maintain their physical properties and appearance over long periods, even under harsh outdoor conditions involving UV radiation, rainfall, and temperature changes. It is indispensable in applications requiring durability and a long service life, such as building exteriors, automotive coatings, and outdoor infrastructure materials. It is valued as a high-performance material that reduces maintenance frequency and contributes to a sustainable society.

Calcium carbonate with excellent heat resistance maintains product shape, mechanical properties, and stability even in high-temperature environments. It is used in automotive engine compartment parts, heat dissipation materials for electronic devices, and high-temperature sealants for the prevention of deformation and degradation under severe thermal loads while ensuring reliability and safety. Its importance is growing as EV adoption expands and electronic devices become more compact and densely integrated.

Calcium carbonate with slip resistance imparts appropriate frictional resistance during the application of viscous materials, preventing slippage and sagging. In sealant and plastisol applications, this property maintains stable film thickness and shape on vertical and inclined surfaces and improves work efficiency and application precision. It contributes to improved quality and safety in environments requiring high-precision application work, such as automotive production lines and construction sites.

Calcium carbonate that contributes to improved adhesion enhances the bond strength between dissimilar materials and suppresses peeling and interfacial failure. In sealants and adhesives, this property is essential for ensuring long-term durability and reliability. As today’s bonding technologies become more sophisticated—such as joining of dissimilar materials for automotive weight reduction and the development of high-performance composites—it serves as a key foundational material that supports product reliability and safety.

Calcium carbonate with excellent dimensional stability suppresses changes in product shape due to temperature and humidity variations, maintaining high precision. This property is essential for ensuring the functionality and reliability of electronic device substrates, optical films, and precision plastic parts. In today’s manufacturing scene, where miniaturization and high density continue to advance, it plays a vital role in maintaining high processing precision and product performance over the long term.

Calcium carbonate with excellent insulating properties has high electrical resistance and prevents current leakage and short circuits in electrical and electronic materials. It is used in cable sheathing, sealants for electronic components, and electrical insulation sheets, ensuring product safety and reliability. With the spread of EVs and today’s trend toward miniaturization and higher density in electronic devices, it plays an important role in maintaining stable electrical performance.
