What is Oxidized Bitumen 90/40?

Oxidized bitumen 90/40 is produced by blowing air through hot bitumen at high temperatures. This process alters the chemical structure of the bitumen, increasing its softening point and decreasing its penetration rate. The result is a material that is more resistant to temperature variations, aging, and mechanical stress, making it ideal for a wide range of industrial applications.

Properties of Oxidized Bitumen 90/40

  • Increased Hardness: The oxidation process increases the hardness of the bitumen, making it more durable and suitable for heavy-duty applications.
  • Higher Softening Point: Oxidized bitumen 90/40 has a higher softening point, which means it can withstand higher temperatures without losing its structural integrity.
  • Improved Elasticity: The material becomes more elastic, providing better performance under mechanical stress and thermal expansion.
  • Enhanced Weather Resistance: It is more resistant to weathering, UV radiation, and oxidation, ensuring a longer lifespan in outdoor applications.
  • Reduced Penetration Rate: The decreased penetration rate makes it more suitable for applications requiring a stable and rigid material.
