The effectiveness of Carbon Black N550 as a performance-enhancing additive in polymers, particularly rubber and plastics, is intrinsically linked to its specific physical and chemical properties. Understanding these carbon black N550 specifications is crucial for manufacturers aiming to achieve precise performance outcomes. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality N550 and emphasizes the importance of material knowledge for optimal application. This article explores the key specifications and their impact on polymer properties, alongside procurement considerations.

At the forefront of N550 specifications is the Iodine Adsorption Number, typically around 43 ± 5 g/kg for this grade. This value indicates the capacity of the carbon black to adsorb iodine molecules, which serves as a proxy for its surface area. A higher iodine adsorption number generally correlates with a finer particle size and a larger surface area, leading to greater reinforcement in polymer matrices. For rubber applications, a higher surface area means more contact points with the polymer chains, resulting in enhanced tensile strength and modulus. Manufacturers need to consider this when formulating for specific mechanical requirements.

Another critical specification is the DBP (Dibutyl Phthalate) Absorption Number, which for N550 is around 121 ± 5 cm³/100g. DBP absorption is an indicator of the carbon black's structure, specifically how it forms aggregates and the degree of branching within these aggregates. A higher DBP absorption value suggests a more complex, branched structure, which can influence the compound's viscosity, stiffness, and processing behavior. This parameter is particularly important for applications requiring good extrusion properties, where the structure of the carbon black plays a significant role in the flow characteristics of the compound. When looking to buy N550, understanding its DBP absorption is key to predicting its processing performance.

The surface area, often measured by CTAB (Cetyltrimethylammonium Bromide) or Nitrogen adsorption, further defines N550's reinforcing potential. While Iodine adsorption gives a general idea, these methods provide more specific measurements of the accessible surface area. For N550, the CTAB surface area typically falls within the range of 38-46 x 10³ m²/kg. A larger surface area enables more effective filler-polymer interaction, leading to improved mechanical properties such as hardness, tear strength, and abrasion resistance. This is why selecting the right grade based on these carbon black N550 properties is vital for achieving desired performance.

In plastics, N550 is often used as a pigment and reinforcing agent. Its fine particle size and surface area contribute to UV stabilization and improved mechanical strength in various plastic compounds. For manufacturers, the consistent quality and adherence to specifications provided by suppliers like NINGBO INNO PHARMCHEM CO.,LTD. are essential. When planning a purchase, it is advisable to consult with the supplier regarding the specific application and the most suitable grade of carbon black. Evaluating the carbon black N550 price against these technical specifications ensures that you are investing in a material that will deliver the required performance enhancement.

In conclusion, a thorough understanding of Carbon Black N550 specifications – including Iodine Adsorption, DBP Absorption, and surface area – is fundamental for optimizing polymer performance.
