Understanding Industrial applications of oxidized bitumen 75/25

What is Oxidized Bitumen 75/25?

Oxidized Bitumen 75/25, also known as Blown Bitumen, is a semi-solid, chemically altered grade of bitumen made by blowing air through penetration-grade bitumen at high temperature. The grade 75/25 refers to a softening point of 75°C and a penetration value of 25 dmm, indicating its moderate hardness and good thermal resistance.

It offers a balance between flexibility and durability, making it ideal for moderate climate industrial applications where both adhesion and temperature resistance are essential.

Technical Properties of Oxidized Bitumen 75/25

Chemical Composition

Oxidized bitumen is composed of hydrocarbons derived from crude oil, similar to other types of bitumen. However, the oxidation process alters its chemical structure, increasing the content of asphaltenes and resins while reducing the proportion of oils. This modification results in a bitumen with higher viscosity and improved thermal and chemical stability.

Physical Properties

• Softening Point: Approximately 75°C
• Penetration Value: Approximately 25 dmm (decimillimeters)
• Ductility: Reduced compared to non-oxidized bitumen, providing increased hardness.
• Thermal Stability: Enhanced stability at higher temperatures.
• Weather Resistance: Improved resistance to environmental factors such as UV radiation and oxidation.

These properties make Oxidized Bitumen 75/25 suitable for applications where durability, stability, and resistance to environmental conditions are crucial.

Production of Oxidized Bitumen 75/25

Oxidation Process

The production of Oxidized Bitumen 75/25 involves a controlled oxidation process, which typically includes the following steps:

1. Feedstock Selection: Suitable bitumen feedstock is selected based on its composition and properties.
2. Heating: The bitumen feedstock is heated to a specific temperature to facilitate the oxidation process.
3. Air Blowing: Air is blown through the heated bitumen, causing a chemical reaction between the bitumen and oxygen. This process increases the asphaltene content, resulting in a harder and more stable bitumen.
4. Cooling: The oxidized bitumen is then cooled and solidified to achieve the desired properties.

Quality Control

Quality control is critical in the production of Oxidized Bitumen 75/25 to ensure consistency and performance. This involves testing the softening point, penetration value, ductility, and other physical properties to meet industry standards and specifications.

Peak Universal Business adheres to stringent quality control measures to provide high-quality Oxidized Bitumen 75/25, ensuring its reliability for various industrial applications.
