Air-Blowing Bitumen

28Edge supplies premium-grade Air-Blowing Bitumen, also known as oxidized bitumen, produced through controlled air-blowing of penetration-grade bitumen at advanced refineries across the Middle East and Asia. Our air-blown bitumen is characterized by enhanced softening point, improved viscosity, and superior temperature stability, making it ideal for industrial, roofing, and waterproofing applications. We supply in bulk, drum, and block form under FOB, CIF, and CFR trade terms, ensuring consistent quality and efficient global delivery.

Air-blowing is a refining process in which hot air is passed through selected grades of bitumen under specific temperature and pressure conditions. This process increases oxidation and polymerization, resulting in a harder, more elastic, and thermally stable product. The resulting oxidized bitumen exhibits excellent resistance to deformation and aging, maintaining performance in both high and low temperature environments.

28Edge’s Air-Blown Bitumen conforms to ASTM D36, D5, and D92 standards, with strict control over softening point, penetration value, flash point, and loss on heating. Our products are available in grades such as 85/25, 90/40, 95/25, and 115/15, covering a range of industrial uses from roofing sheets and pipe coatings to insulation and electrical applications. Every batch is tested and certified by SGS or Bureau Veritas, ensuring compliance with international specifications.

With its durability, adhesive strength, and resistance to weathering, air-blown bitumen remains a cornerstone material in infrastructure, construction, and waterproofing sectors. 28Edge delivers a reliable supply of high-performance oxidized bitumen to clients worldwide, maintaining consistency, safety, and technical excellence in every shipment.
