ABOUT OXIDIZED BITUMEN 75/25
Oxidized Bitumen 75/25 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. This bitumen grade is also commonly known as Blown Bitumen, Air-Blown Bitumen or Oxidized Asphalt.
PETRO TAR CO. manufactures Oxidized Bitumen 75/25 in its pure form, without the addition of Gilsonite or mineral fillers. The product is manufactured with controlled composition and consistent physical properties, making it suitable for industrial formulations and production processes where material consistency is important.
Oxidized Bitumen 75/25 can be incorporated into a broad range of construction, infrastructure, industrial and specialty applications, including waterproofing systems, construction chemicals, mastics, sealants, protective coatings, pipe and pipeline coatings, and other bitumen-based formulations. Depending on the specific formulation and technical requirements, it may also be used in selected roofing, electrical and other industrial applications.
With its defined hardness and softening characteristics, the grade can be considered for formulations requiring controlled penetration, material consistency and resistance to flow under elevated temperatures. Depending on the formulation and service conditions, it may be suitable for applications operating under moderate temperature conditions and, where technically compatible, warmer environments.
The suitability of Oxidized Bitumen 75/25 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.
