Iran Blown Bitumen manufacturer

The refinery bitumen is further treated by the introduction of processed air. This will give us Blown Bitumen. By maintaining a controlled temperature, the air is introduced under pressure into soft bitumen.

Compounds of higher molecular weight are formed by the reaction of this introduced oxygen and bitumen components. Thus, the Asphaltenes and the Maltenes content increases resulting in a harder mix. This harder mix has a lower ductility and temperature susceptibility.

The Oxidized Bitumen is used in industrial applications such as roofing and coating for pipes. By this method of processing, the bitumen that has a lower penetration can be manufactured, which can be employed for paving roads.

Iran is the biggest manufacturer of Blown Bitumen in the world

Iran producing the largest quantity of oxidized bitumen in various grades as below:

Oxidized bitumen 75/25

Oxidized bitumen 85/25

Oxidized bitumen 95/25

Oxidized bitumen 90/40

Also, medium grade oxidized bitumen 90/10

Oxidized bitumen 90/15 and hard grade including

Oxidized Bitumen 115/15

Oxidized bitumen 105/15

Oxidized bitumen 105/35

Oxidized bitumen 150/5

Iran Blown Bitumen is high quality and economy compare other countries since oil price in Iran is cheaper and a lot of manufacturers producing air blown asphalt.
