OXIDIZED BITUMEN 85/35

DESCRIPTION OF OXIDIZED BITUMEN 85/35

Oxidized Bitumen 85/35 or blown asphalt 85/35 (blown bitumen 85/35) is a form of bitumen that is manufactured by blowing air over pure bitumen (similar to penetration bitumen). Oxidized Bitumen 85/35 has a lower penetration grade and a greater softening point than conventional bitumen. Airflow polymerizes the asphaltene included in this bitumen, transforming it into stretchy bitumen. As denoted by the symbol R, this bitumen is referred to as Rubberized Bitumen due to its rubber properties. These figures represent the point of softening point and the degree of penetration. For instance, Oxidized Bitumen R85/35 indicates that this bitumen has a softening point of 85 and a penetrability grade of 35.

We manufacture the highest quality Oxidized Bitumen 85/35 ( Blown Asphalt 85/35  ) in different types and export them from Iran and the UAE to other countries around the world.

  • Oxidized Bitumen 85/35 UAE ( Blown Asphalt 85/35 UAE )

OXIDIZED BITUMEN 85/35 PRODUCTION PROCESS:

The BBU reactor at the refinery must first expose penetration-grade bitumen to hot air at a temperature that falls anywhere between 240 and 270 degrees Celsius in order to produce oxidized bitumen 85/35. This requires the refinery to maintain a temperature that ranges between 220 and 230 degrees Celsius. The reaction that takes place within the reactor between the hydrogen atoms of bitumen and the oxygen atoms of air is induced by heated air. This reaction takes place between the bitumen and the air.

The next thing that takes place is that it starts to create some steam, which then has to have the oxidation chamber emptied of it once it has been produced. This results in the presence of oxidized bitumen as a direct consequence.

APPLICATIONS OF OXIDIZED BITUMEN 85/35

Road construction, hydropower projects, roofing, flooring, mastics, the oil and gas sectors, and electrical applications are just a few of the uses for oxidized bitumen 85/35.

  • Roads: Blown Asphalt 85-35 is suitable for road construction, paving, and maintenance. It can be used as an additive in asphalt for roads, highways, railroads, and parking lots.
  • Hydro projects: Oxidised Bitumen 85/35 is utilized as a canal lining material. This kind of bitumen may be employed in additional hydro projects such as embankment and dam construction, hydraulic structures, dam lining protection, and sand stabilization.
  • Roofing: Blown Bitumen 85-35 is used in roofing felts, shingle roofs, damp-proof coating compositions, carriage roofing compounds, liquid roof coatings, and plastic cements. It is often the best solution for roof waterproofing.
  • Flooring: One of the principals uses for Oxidized Bitumen 85.35 is flooring. Acid- and alkali-resistant bitumen mastic may be used to prevent corrosion on the surfaces of chemical plants, fertilizer plants, steel factories, and other facilities. It may also repair parquet flooring.
  • Oil and gas industry: in addition to Cutback Bitumen MC30, Oxidized Bitumen 85-35 is commonly used to protect pipelines from corrosion and rust.
  • Bitumen 85/35 is utilized as a laminated board adhesive in the electrical industry. It has the ability to seal electrical connection boxes. It is used in the cable industry, lithium-ion batteries, and wires.
