For professionals in the rubber and plastics industries, a thorough understanding of raw material specifications is crucial for optimal product development and manufacturing. Carbon Black N330 is a highly versatile grade, but its effectiveness hinges on meeting specific application requirements. As a leading supplier of chemical raw materials, we aim to provide clarity on the key specifications of Carbon Black N330, empowering you to make informed purchasing decisions. We are a dedicated manufacturer in China, offering premium quality.

The classification of carbon black grades is primarily based on their physical properties, such as iodine adsorption value, DBP absorption value, and CTAB surface area. These parameters are direct indicators of the carbon black's particle size, structure, and surface activity, which in turn dictate its performance in rubber compounds and other applications. Knowing these specifications is essential for procurement managers and R&D scientists. We are committed to providing accurate data for our Carbon Black N330.

Iodine Adsorption Value: This value measures the amount of iodine that can be adsorbed by a specific weight of carbon black, indicating the approximate surface area of the particles. For Carbon Black N330, a typical iodine adsorption value ranges from 73-91 g/kg. A higher iodine value generally suggests smaller particle sizes and a greater surface area, contributing to stronger reinforcement.

DBP Absorption Value: Dibutyl Phthalate (DBP) absorption measures the structure of the carbon black – essentially, how the particles are aggregated. For Carbon Black N330, the DBP absorption value is typically around 102 cm³/100g. A higher DBP absorption indicates a more branched and complex structure, which can improve dispersion and processing characteristics in rubber compounds.

CTAB Surface Area: The Cetyl Trimethyl Ammonium Bromide (CTAB) absorption value is another measure of surface area, often correlating closely with iodine adsorption. For N330, the CTAB absorption is generally between 73-91 x 10³ m²/kg. This provides another metric for assessing the reinforcing potential of the carbon black.

Tinting Strength: This refers to the pigmenting capacity of the carbon black. Carbon Black N330 generally has a tinting strength of 96-112%, indicating its effectiveness in providing deep black coloration, which is beneficial for both masterbatches and some coating applications.

Understanding these specifications allows you to precisely match the carbon black grade to your product's needs. For example, if high abrasion resistance is paramount, as in tire treads, the balance of iodine and DBP absorption values in N330 is highly advantageous. When you decide to buy Carbon Black N330, ensure your supplier provides detailed Certificates of Analysis (CoA) that confirm these critical specifications.
