[News & Trends]:Choosing the Right Black Pigment: The Difference between Sulfide Black and Reactive Black

In industries such as painting, painting, plastic products, and rubber products, black is a commonly used color. When choosing black pigments, one often faces two options: sulfur black and reactive black. These two black pigments may have similar appearances, but they have significant differences in chemical properties, application areas, and performance characteristics


Let's take a look at sulfur black. Sulfide black is a black pigment made from sulfide pigments, commonly used sulfur black pigments include copper sulfide, iron sulfide, etc. The characteristics of sulfur black are rich color, deep color depth, good covering and light resistance. Sulfide black has a strong ability to absorb light and can be used as an anti reflective coating for optical equipment such as night vision devices and high-end cameras. Sulfur black pigment particles are larger and have a wide particle size distribution, making it a good choice for delicate paintings and high-quality paint coatings


Compared to sulfur black, activated black is a black pigment made from activated carbon. Activated carbon has a great specific surface area and microporous structure, so the pigment particles of activated black are finer and have better dispersibility. The characteristic of active black is its strong adsorption capacity, with good deodorization, purification, and adsorption performance. Activated black is widely used in fields such as ink, rubber, and wall paint, especially in products that require adsorption and purification functions. Reactive black has a high requirement for the mild adsorption characteristics of pigments and is suitable for advanced painting or occasions that require more delicate effects


When choosing black pigments, it is necessary to decide whether to use sulfur black or reactive black based on specific application requirements. If you have high requirements for the covering power and light resistance of pigments, and do not need to have deodorization and purification functions, then sulfur black will be an ideal choice. If you need to adsorb and remove harmful gases or odors, and want the pigment particles to be finer and more dispersed, then activated black will be a better choice


In short, choosing the right black pigment has a significant impact on the quality and effectiveness of products in fields such as painting and painting. Understanding the difference between sulfur black and active black, and selecting according to specific application needs, is the key to ensuring product quality and meeting user needs. I hope this article's introduction can be helpful for you when choosing black pigments.
