Ultra-fine High Alkaline White Carbon Black

Updated: 2026-08-26

Overview

Ultrafine high-alkaline white carbon black is a specialized form of silica characterized by its fine particle size and elevated pH level. It is widely utilized in industrial applications due to its unique properties, such as high surface area and alkalinity. This material is particularly valued in the rubber and polymer industries for its ability to enhance mechanical strength and processing efficiency. Produced through advanced chemical processes, ultrafine high-alkaline white carbon black offers superior performance compared to conventional silica. Its high alkalinity makes it suitable for applications requiring pH stabilization, while its fine particle size ensures excellent dispersion in various matrices.

Physical and Chemical Properties

Ultrafine high-alkaline white carbon black exhibits a range of distinctive physical and chemical properties. Its fine particle size, typically in the nanometer range, contributes to a high surface area, which enhances its reactivity and reinforcing capabilities. The material is chemically inert under normal conditions but demonstrates high alkalinity, often with a pH above 9. Key physical properties include a white powdery appearance, low bulk density, and excellent thermal stability. The material is insoluble in water and most organic solvents, making it ideal for use in aqueous and non-aqueous systems. Its high melting point ensures stability in high-temperature applications.

Main Applications

The primary applications of ultrafine high-alkaline white carbon black span several industries. In the rubber industry, it serves as a reinforcing filler, improving tensile strength, abrasion resistance, and durability of rubber products. It is also used in coatings and adhesives to enhance viscosity, stability, and mechanical properties. In the plastics sector, this material acts as a filler and anti-blocking agent, improving processing and end-product performance. Additionally, it finds use in specialty chemicals, where its high alkalinity and fine particle size are leveraged for pH adjustment and surface modification.

Safety and Storage

Handling ultrafine high-alkaline white carbon black requires adherence to safety protocols to minimize health risks. Inhalation of dust particles should be avoided, and appropriate personal protective equipment (PPE), such as masks and gloves, must be worn during handling. The material is generally non-toxic but can cause irritation upon contact with skin or eyes. Storage conditions are critical to maintaining the material's quality. It should be kept in a dry, cool environment, away from moisture and incompatible substances. Properly sealed containers are recommended to prevent contamination and degradation.

B2B Procurement Guide

When procuring ultrafine high-alkaline white carbon black, buyers should consider several factors to ensure product suitability. Key specifications include pH level, particle size distribution, and purity, which should align with the intended application. It is advisable to request technical data sheets and certificates of analysis from suppliers. Price negotiations should account for bulk purchase discounts and logistics costs. Buyers are encouraged to establish long-term relationships with reputable suppliers to secure consistent quality and reliable delivery schedules. Sampling and testing before large-scale procurement are recommended.
