Nano Calcium Carbonate for Rubber | Quality Product from China Suppliers and Factory
Product Description
Superior Dispersion & Enhanced Mechanics
USEEN nano calcium carbonate possesses a unique nanoscale cubic crystal structure and high specific surface area. Through optimized surface treatment processes, it achieves highly uniform dispersion within the rubber matrix. This characteristic directly translates into a comprehensive improvement in rubber compound performance, resulting in rubber products with superior overall mechanical properties compared to those using ordinary calcium carbonate.
Whitening & High-Performance Reinforcement
Based on its excellent dispersion characteristics and reinforcing effects, USEEN nano calcium carbonate can significantly improve tear resistance, compression set resistance, and flexural fatigue performance while maintaining high elongation. This product can partially or completely replace silica and carbon black, providing excellent whitening effects while achieving reinforcement, thus meeting the dual optical and mechanical requirements of transparent and translucent rubber products.
Transparent & Innovative Rubber Solutions
USEEN nano calcium carbonate possesses unique reinforcing and whitening dual functionalities, giving it exceptional value in the high-end rubber products sector. It is particularly suitable for applications with stringent requirements for transparency, color purity, and durability. This product not only helps upgrade the performance of rubber products but also provides customers with innovative solutions that balance high product performance and production cost-effectiveness by optimizing the filler system structure.

Frequently Asked Questions
How does nano calcium carbonate improve rubber compound performance compared to standard calcium carbonate?
With an average nanoscale particle size of 70±5 nm and optimized surface modification, it achieves ultra-uniform dispersion within the rubber matrix. This structure significantly enhances mechanical properties such as tear resistance, tensile strength, and flexural fatigue resistance.
Can USEEN nano calcium carbonate replace carbon black or precipitated silica?
Yes. It can partially or completely replace silica and carbon black in specific formulations, offering an optimal balance between high reinforcement, superior whitening effect, and cost efficiency.
What role does the fatty acid surface treatment play?
The organic fatty acid surface coating reduces particle surface energy, prevents agglomeration, improves compatibility with non-polar rubber matrices, and lowers Mooney viscosity for smoother processing and compounding.
Is this product suitable for transparent or translucent rubber goods?
Yes. Due to its high brightness (Min. 95%), controlled cubic crystal morphology, and fine dispersion, it is ideally suited for transparent, translucent, and light-colored high-end rubber products without compromising optical clarity.
Do you provide customized specifications or OEM packaging services?
Yes, supported by our professional R&D center and large-scale manufacturing facilities, we offer tailor-made surface modification, grain sizing, and OEM packaging solutions to meet exact industrial requirements.
