Description of Oxidized Bitumen 85/25 – Iran Bitumen Supply │ IBITMCO
Oxidized Bitumen 85/25 is a high‑quality, semi‑solid industrial bitumen produced through the controlled oxidation of petroleum bitumen. In the production reactor, a blend of Vacuum Bottom (VB) and Vacuum Slops (VS) is exposed to hot air under specific pressure and temperatures ranging from 200–300°C. During this process, hydrogen atoms in the bitumen molecules react with oxygen, creating a polymerized structure with lower penetration and higher softening point than the original bitumen. The resulting product—Bitumen 85/25—has a softening point of 85°C and a penetration value of 25 dmm, making it a durable, stable, and highly reliable oxidized bitumen suitable for a wide range of industrial and construction applications. At Iran Bitumen Supply │ IBITMCO, our Oxidized Bitumen 85/25 is produced by blowing hot air through Bitumen 60/70, resulting in a product with superior adhesion, waterproofing capability, and long‑term performance. It remains predominantly solid at ambient temperatures and offers excellent resistance to heat, aging, and deformation.

Application Guidelines for Oxidized Bitumen 85/25
To achieve proper flow and viscosity, Bitumen 85/25 must be heated to approximately twice its softening point. Before application: Surfaces must be clean, dry, and free of dust, loose particles, curing compounds, and irregularities. Proper heating ensures optimal adhesion and performance. Failure to prepare the surface correctly may reduce bonding strength and durability.
