The Technical Specifications of Carbon Black N990: A Deep Dive for Rubber Professionals
For rubber compounders and engineers, understanding the precise technical specifications of raw materials is fundamental to achieving optimal product performance. Semi-Reinforcing Carbon Black N990 is no exception, and delving into its key parameters provides valuable insights into its behavior and application suitability. NINGBO INNO PHARMCHEM CO.,LTD. provides a closer look at these critical specifications.
One of the most important metrics for carbon black is the Iodine Adsorption Number (g/kg). For N990, this value typically ranges around 14 ± 6 g/kg. A lower Iodine Adsorption Number indicates a larger particle size and a lower surface area. This directly relates to N990’s characteristic of providing good processability and lower heat build-up, as there are fewer active sites for interaction within the rubber matrix compared to finer grades. It signifies a less aggressive reinforcing effect, aligning with its semi-reinforcing classification.
Another crucial specification is the Oil Absorption Number (OAN), often measured in cm³/100g. For N990, this is typically around 47 ± 6 cm³/100g. OAN is an indicator of the carbon black's structure – essentially, how the primary particles are aggregated into larger structures. A higher OAN generally suggests a higher structure, meaning more 'empty space' within the aggregate that can absorb oil. For N990, this value reflects its moderate structure, contributing to its balance of reinforcement and processability. It indicates the volume the carbon black will occupy in the rubber compound, influencing viscosity and reinforcement.
Other specifications detailed in product data sheets include Carbon Content (typically >=99.3%), Acetone Extract (≤0.2%), and Heating Loss at 125°C (≤0.5%). These parameters provide further assurance of the carbon black's purity and consistency. For instance, a low Acetone Extract suggests minimal organic impurities, while low Heating Loss indicates low moisture content, both vital for predictable compound behavior and vulcanization. By understanding these technical specifications, rubber professionals can confidently select and utilize Semi-Reinforcing Carbon Black N990 from NINGBO INNO PHARMCHEM CO.,LTD. for their specific application needs.
