For professionals in the rubber industry, a thorough understanding of the raw materials used is crucial for developing high-performance products. Carbon black, particularly specific grades like Semi-Reinforcing Furnace Black N990, offers unique properties that can significantly influence the final characteristics of rubber compounds. This article aims to demystify the technical aspects of N990 and highlight why it is a preferred choice for many demanding applications. When you need to buy carbon black N990, knowing its technical profile helps in selecting the right carbon black N990 supplier in China.

Semi-Reinforcing Furnace Black N990 is classified by its ASTM designation, which indicates its specific performance attributes. Its defining features are its large particle size and low structure. These physical characteristics directly impact its performance as a reinforcing filler. The large particle size generally leads to lower reinforcement and modulus compared to finer carbon blacks, but this is compensated by other beneficial properties.

The low structure of N990 contributes to excellent processing characteristics. This means that during compounding, the carbon black disperses more easily into the rubber matrix, requiring less energy and time. This ease of dispersion is a key factor for manufacturers aiming to optimize their production cycles and reduce operational costs. Furthermore, its low structure results in a lower hysteresis loss, meaning less energy is wasted as heat during flexing. This is directly related to the benefit of reduced heat build-up, which we previously discussed.

The high elongation and resilience provided by N990 are direct results of its particle characteristics. These properties are essential for applications where the rubber compound must undergo significant deformation and return to its original shape. When evaluating the high elongation rubber additive price, it's important to consider the enhanced flexibility and durability N990 brings to the final product.

As a carbon black N990 manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our N990 meets stringent quality controls. Technical specifications such as Iodine adsorption number (typically around 14 ± 6 g/kg) and Oil Absorption Number (OAN, typically 47 ± 6 10-5m3/kg) are meticulously managed. These parameters are critical indicators of the carbon black's surface area and structure, directly correlating with its performance in rubber.

By choosing N990 from a trusted carbon black N990 manufacturer like NINGBO INNO PHARMCHEM CO.,LTD., you are investing in a material that offers a superior combination of processability, elasticity, and durability for your rubber formulations.
