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.
At Kane Ara, we supply industrial oxidized bitumen in multiple grades with consistent quality, export-ready packaging, and technical documentation for international B2B customers.
Oxidized Bitumen Grades
Selecting the correct oxidized bitumen grade depends on the operating temperature, flexibility requirements, and intended application. Each grade is identified by its approximate softening point and penetration value.
| 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 85 25 | Stable performance in moderate climates | Roofing felt, adhesives |
| 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 |
Why Grade Selection Matters
Choosing the proper oxidized bitumen grade helps achieve:
- Better waterproofing performance
- Longer service life
- Improved adhesion
- Higher temperature resistance
- Reduced maintenance costs
- Better compatibility with industrial production processes
Rather than selecting a product solely by name, industrial buyers should match the required softening point, penetration value, packaging type, and application requirements.
Why Buy Oxidized Bitumen from KaneAra?
KaneAra helps international buyers reduce purchasing risks through reliable product quality, transparent cooperation, and professional export support.
Oxidized Bitumen Price
The oxidized bitumen price depends on several technical and commercial factors rather than a fixed market value.

Frequently Asked Questions
1- How Do I Choose the Right Oxidized Bitumen Grade?
Choosing the correct oxidized bitumen grade depends on factors such as softening point, penetration value, service temperature, and application. Whether you need oxidized bitumen 85/25, 90/10, 110/30, or 115/15, selecting the appropriate grade ensures better performance, durability, and cost efficiency for your project.
2- What is the difference between oxidized bitumen and penetration bitumen?
Penetration bitumen is primarily used for road paving, while oxidized bitumen is engineered for industrial applications requiring greater heat resistance, lower penetration, and enhanced waterproofing performance.
3- Which oxidized bitumen grade should I choose?
The appropriate grade depends on your application, required softening point, operating temperature, flexibility, and industry standards. Technical consultation is recommended before purchasing.
4- What industries use oxidized bitumen?
Oxidized bitumen is commonly used in roofing, waterproofing, pipe coating, insulation, expansion joints, adhesives, mastics, battery manufacturing, corrosion protection, and industrial construction.
5- Can oxidized bitumen be supplied for export?
Yes. Kane Ara supplies export-ready oxidized bitumen with industrial packaging, COA, TDS, MSDS, and logistics support for international B2B customers.
