Overview
60nm calcium carbonate represents an advanced material in the family of industrial mineral fillers, characterized by its exceptionally small particle size averaging 60 nanometers. This nano-scale calcium carbonate is produced through sophisticated precipitation processes that carefully control crystal growth and particle formation. The ultra-fine dimensions give the material unique properties compared to conventional calcium carbonate products, including dramatically increased surface area and improved interaction with polymer matrices. As a versatile functional filler, 60nm calcium carbonate has gained significant importance in modern manufacturing industries. Its development responds to the growing demand for high-performance additives that can simultaneously enhance material properties while reducing production costs. The material's nano-scale dimensions allow for unprecedented levels of reinforcement and modification in composite materials.
Physical and Chemical Properties
The 60nm particle size gives this calcium carbonate variant a specific surface area typically ranging from 25-35 m²/g, approximately ten times greater than micron-sized counterparts. This extensive surface area significantly improves its interaction with other materials in composite systems. The particles generally exhibit a cubic or spindle-like morphology with narrow size distribution, contributing to uniform dispersion in host materials. Chemically, 60nm calcium carbonate maintains the same composition as conventional calcium carbonate but with enhanced reactivity due to its nano-scale dimensions. The material shows improved thermal stability up to approximately 400°C before beginning to decompose. Surface treatments such as stearic acid coating are commonly applied to improve compatibility with organic matrices and prevent particle agglomeration during storage and processing.
Main Applications
In the plastics industry, 60nm calcium carbonate serves as a high-performance filler for PVC, PP, PE, and engineering plastics, where it improves tensile strength, impact resistance, and surface finish while reducing material costs. The nano particles act as nucleation agents that can modify crystallization behavior in semi-crystalline polymers. For rubber products, it enhances tear resistance and reduces compression set in seals and gaskets. The coatings industry utilizes this material to improve scrub resistance, weathering performance, and opacity in water-based paints. In paper manufacturing, it functions as both filler and coating pigment, enhancing paper brightness, smoothness, and ink receptivity. Emerging applications include use in adhesives, where it improves viscosity control and bond strength, and in food packaging materials as a cost-effective, food-safe additive.
Safety and Storage
While calcium carbonate is generally considered non-toxic, the nano-scale form requires special handling precautions due to its potential to form airborne dust clouds. Appropriate respiratory protection (NIOSH N95 or equivalent) should be used when handling the dry powder to prevent inhalation exposure. The material should be stored in original, sealed containers in a dry environment at ambient temperature to prevent moisture absorption and caking. Fire safety measures should address the potential for dust explosion hazards, including prevention of static electricity buildup and elimination of ignition sources in handling areas. Spills should be cleaned promptly using wet methods or vacuum systems equipped with HEPA filters to prevent dust dispersion. The material is chemically stable but should be kept away from strong acids, which will cause vigorous decomposition.
B2B Procurement Guide
When sourcing 60nm calcium carbonate, industrial buyers should prioritize suppliers who can provide comprehensive technical data sheets including particle size distribution analysis (with D50, D90 values), surface treatment specifications, and moisture content. Certification to ISO 9001 and other relevant quality standards indicates reliable production control. Sample evaluation should test for dispersion quality in the intended application system. Bulk procurement typically offers significant cost advantages, with common packaging options including 25kg bags, big bags (500-1000kg), and bulk tanker deliveries for large-scale users. Buyers should verify logistics capabilities, as some suppliers specialize in regional distribution while others operate globally. Technical support availability for application development can be valuable, particularly for companies new to nano-material utilization.
