Before bulk orders
Oxidized bitumen, also known as air-blown bitumen or oxidized asphalt, is a specially processed petroleum bitumen produced by passing hot air through penetration grade bitumen under controlled conditions. This process increases the material’s softening point while reducing penetration, resulting in a product with improved heat resistance, durability, and chemical stability.
Because of its waterproofing performance, adhesion, and resistance to weathering, oxidized bitumen is widely used in roofing membranes, waterproofing systems, pipe coating, insulation boards, expansion joints, adhesives, mastics, battery compounds, and various industrial applications.
Different oxidized bitumen grades are manufactured to match specific performance requirements, making product selection an important part of every industrial project.
Grade selection depends on your required softening point and penetration value, not the product name alone. Commonly requested oxidized bitumen grades include:
Grade | Typical Characteristics | Common Applications |
Oxidized Bitumen 75/25 | Flexible with moderate hardness | Roofing, waterproofing membranes |
Oxidized Bitumen 85/25 | Excellent balance between flexibility and heat resistance | Waterproofing, industrial sealing |
Oxidized Bitumen 90/10 | High softening point with low penetration | Pipe coating, insulation |
Oxidized Bitumen 90/15 | Strong thermal stability | Expansion joints, industrial compounds |
Oxidized Bitumen 95/25 | Improved durability and adhesion | Waterproofing systems |
Oxidized Bitumen 110/30 | Flexible grade for specialized industrial uses | Protective coatings |
Oxidized Bitumen 115/15 | High-temperature resistance | Roofing membranes, insulation boards |
Oxidized Bitumen 125/5 | Very hard grade | Battery compounds, heavy-duty sealing |
Oxidized Bitumen 135/5 | Maximum hardness and heat resistance | Specialized industrial applications |
We also supply harder grades for battery compounds and heavy-duty sealing. Confirm your target softening point and penetration with our technical team before ordering — that match is what determines performance in your finished product.
For asphalt-modification projects that need an even higher softening point, some buyers pair oxidized bitumen with gilsonite — our technical team can advise on blending ratios if that fits your application.
