Carbon Black N326


Carbon Black N326 is not just another industrial material; it's a versatile substance with a multitude of applications.

Carbon Black N326 Also known as medium reinforcing furnace black, Carbon Black N326 is a finely divided carbonaceous material produced by the incomplete combustion of hydrocarbons. It falls under the category of carbon black, which encompasses a range of carbon-based materials primarily used as reinforcing fillers in rubber and other elastomeric compounds. N326 is distinguished by its medium particle size and surface area, making it suitable for a variety of applications.

Key Properties of Carbon Black N326
  • Particle Size: Carbon Black N326 has a medium particle size, typically ranging from 30 to 40 nanometers. This particle size distribution contributes to its excellent reinforcing properties in rubber.
  • Surface Area: With a moderate surface area, N326 offers a balance between reinforcement and dispersion, making it an ideal choice for various rubber products.
  • Structure: The unique structure of Carbon Black N326 results in improved abrasion resistance, tensile strength, and resilience in rubber compounds.
  • Color: N326 is a black powder, and its color imparting properties are utilized in products like inks, paints, and coatings.
