White Carbon Black Application
White Carbon Black and Nano Silica Overview
Nano silica, with its ultra-fine structure, further augments these properties by acting as a highly effective thickening agent and anti-caking additive. It prevents sedimentation in liquid formulations, ensuring consistent product quality and stability over extended periods. Additionally, its anti-caking capabilities maintain material flowability, reducing waste during handling and improving overall production efficiency. The high surface area of nano silica, typically ranging from 200 to 400 m²/g, enhances its reinforcing effect in rubber and plastic compounds, improving tensile strength and abrasion resistance without compromising flexibility.
Together, white carbon black (precipitated silica) and nano silica create synergistic effects that drive performance in demanding applications. White carbon black, primarily composed of silicon dioxide (SiO₂), offers excellent reinforcing properties for elastomers, acting as a substitute for carbon black in light-colored and transparent products. Its porous structure provides superior dispersion in polymer matrices, enhancing tear strength and heat resistance. In paints and coatings, it improves scrub resistance and anti-corrosion properties. In adhesives and sealants, it optimizes viscosity and thixotropy. Their combined benefits make them indispensable in high-performance composites, automotive components, and construction materials, ensuring products meet stringent quality and performance standards in competitive global markets.

Technical Specifications and Properties
Our white carbon black and nano silica products conform to CAS number 112945-52-5, with a purity range of 95-99% as silicon dioxide (SiO₂). Sourced from China, these industrial-grade powders undergo rigorous quality control to ensure consistent particle size distribution, typically between 10-100 nm for nano silica and 1-10 µm for standard white carbon black. The white color and fine powder form facilitate easy incorporation into various matrices.
Key performance indicators include a high specific surface area (BET) of 150-400 m²/g, pH value of 6.0-8.0, and loss on drying below 6%. These properties directly influence thickening efficiency, reinforcement, and anti-caking behavior. The industrial grade ensures cost-effective solutions for bulk applications while maintaining sufficient purity for most non-food uses.
Applications Across Industries
Rubber and Elastomers: As a reinforcing filler, white carbon black enhances tensile strength, tear resistance, and abrasion resistance in tires, conveyor belts, and rubber seals. Nano silica further improves heat dissipation and reduces rolling resistance, contributing to fuel efficiency in automotive applications.
Coatings and Paints: Both grades serve as anti-settling agents and thickeners, preventing pigment sedimentation and improving rheology. They also impart matting effects, scratch resistance, and corrosion protection for marine, architectural, and industrial coatings.
Adhesives and Sealants: Nano silica provides thixotropic control, ensuring stable viscosity during application and preventing sagging. White carbon black reinforces the adhesive bond strength and improves thermal stability.
Plastics and Composites: Used as a processing aid and filler, these materials improve dimensional stability, impact resistance, and surface finish in polypropylene, polyethylene, and PVC compounds. They also reduce mold shrinkage and warpage.
Personal Care and Agriculture: Nano silica acts as a carrier for active ingredients in cosmetics, sunscreens, and pesticides, while white carbon black absorbs moisture and prevents caking in powdered formulations.
