ABOUT OXIDIZED BITUMEN 85/25
Oxidized Bitumen 85/25 is a medium-hard bitumen grade produced from Vacuum Bottom (Vacuum Residue) through a controlled air-blowing process. This process modifies the physical properties of the base bitumen, resulting in a defined balance of hardness, penetration and softening characteristics. With a penetration range of 20–30 dmm and a softening point of 80–90°C, Oxidized Bitumen 85/25 offers controlled flow and deformation resistance for a variety of construction, industrial and specialty applications. This bitumen grade is also commonly known as Blown Bitumen, Air-Blown Bitumen or Oxidized Asphalt.
PETRO TAR CO. manufactures Oxidized Bitumen 85/25 in its pure form, without the addition of Gilsonite or mineral fillers. The product is manufactured under controlled production conditions to maintain consistent composition and physical properties, making it suitable for industrial formulations and production processes where material consistency and predictable performance are important.
Oxidized Bitumen 85/25 can be incorporated into a broad range of construction, infrastructure, industrial and specialty applications, including waterproofing systems, construction chemicals, roofing materials, mastics, sealants, joint-filling compounds, protective coatings, pipe and pipeline coatings, and other bitumen-based formulations. Depending on the specific formulation and technical requirements, it may also be considered for selected electrical, flooring, carpet tile backing, sound-damping, automotive and infrastructure-related applications.
With its defined penetration range and softening point of 80–90°C, Oxidized Bitumen 85/25 provides a practical balance between hardness, adhesion and resistance to flow. These characteristics make the grade suitable for formulations where controlled deformation, dimensional stability and reliable performance under moderate to elevated service temperatures are required. Its suitability for higher-temperature applications should be evaluated according to the complete formulation and actual service conditions.
The suitability of Oxidized Bitumen 85/25 should be determined according to the formulation, processing conditions, application method and expected service environment, ensuring that the selected grade meets the performance requirements of the final application.
