Product Description

One type of Bitumen that produces by pure Bitumen air blowing is named Oxidized Bitumen. This type of Bitumen has a lower needle penetration degree and higher softening point rather than Penetration grades. Oxidized Bitumen or Blown Bitumen is classified into three categories includes Low, Medium, and Hard, which is based on their Penetration and Softening Point.
 
Hot air in the range of **0 to **0℃ was inserted into the reactor and passed thru the pure Bitumen to produce the Oxidized Bitumen; after this process, we have Blown Bitumen. It should be mentioned that the asphaltene available in this type of Bitumen, Blown Bitumen, is Polymerized and gives Bitumen rubber property.
Oxidized Bitumen (or Blown Bitumen) has numerous usage in various industries such as construction, road making and operations, roofing, flooring, mastics, petroleum (or oil and gas) industry, electrical application, power and hydropower industries, paper and pulp manufacturing, sealing and coating, waterproofing, dust proofing, adhesive manufacturing, high-temperature operations, carpet, sound damping, pilling industry, undercarriage sealant, paving and pavement production, etc.
