oxidized bitumen

Iran manufacturer of oxidized bitumen by hot air blown asphalt
Oxidized bitumen CAS No. 64742-93-4 or oxidized bitumen also known as air blown or air refined asphalt has been treated by blowing air through it at elevated temperatures to produce physical properties required for industrial use of the final product.The blown bitumen have been modified by the passage of air , under specific pressure and temperature depend on which grade we need to produce .Oxidized bitumen is of a rubbery consistency and has a higher softening point and greater resistance to flow than a straight run bitumen of the same hardness.Oxidized asphalt are typically used in roofing operation,pipe coating, undersealing for portland cement concrete pavements,hydraulic application and manufacture of paints.

Throughout the world, more than 10 types of bitumen that is produced depend on the type of weather conditions one of them is Oxidised Bitumen.
Oxidised bitumen grades are suitable for sealing saw cuts and joints where there is expected to be the minimum amount of moving in the joint. Their wide temperature range prevents bleeding in high temperature applications. Oxidized bitumen can also be used in industrial applications like roofing, flooring, mastics, pipe coatings, electrical applications.

Oxidized bitumen R 150/5 115/15 105/35 95/25 90/40 90/10 90/15 85/25 85/40 85/25 75/25 which is manufactured at ATDM factory is grade of oxidizing bitumen by hot air and has high softening point and low penetration.
The oxidized bitumen could be packed in plastic bag also craft bag also in drum and possible to deliver hot in bulk tanker.

When the oxidation of bitumen occurs in the presence of catalytic agents , the process is called catalytic oxidation . By the action of catalysts the reaction rate is changed, allowing the oxidation process is faster and more homogeneous throughout the bulk form , in addition to allowing greater process control and final product with different penetration like 115/15 which is 115 is softening point and 15 is penetration.

Depending on the purpose for which it is the oxidized asphalts may also receive different types of polymer additives, in order to increase its plasticity, stickiness, resistance to weathering and oxidation.
