Oxidized Bitumen (Blown Bitumen) – High-Quality Export Grade — Export from Iran
Oxidized Bitumen, also known as Blown Bitumen, is produced by blowing air through penetration bitumen at elevated temperatures. This process increases hardness, softening point, and temperature resistance, making it ideal for industrial, waterproofing, and anti-corrosion applications.
We supply premium Oxidized Bitumen from major Iranian refineries, manufactured under strict quality control and in compliance with international standards including ASTM D977 and EN 13303. Suitable for bulk export to global markets.
Note: Grade notation (e.g., 85/25) indicates softening point (°C) and penetration (0.1 mm). Higher softening point = better heat resistance.
🏭 Janis Group Oxidized Bitumen Capability: We supply premium Oxidized (Blown) Bitumen directly from major Iranian refineries, offering consistent grades (85/25, 95/25, 115/15) with full ASTM D977 and EN 13303 compliance. Every shipment undergoes rigorous SGS inspection for softening point and penetration, serving roofing, waterproofing, and anti-corrosion industries across Africa, Asia, and the CIS.

Which Grade Fits Your Project?
Grade 85/25
Softening Point: 83–88°C
Choose this if: You need a balanced grade for general waterproofing, standard roofing felt, and pipe coating in moderate climates.
Typical buyers: General construction contractors, roofing material manufacturers.
Grade 95/25
Softening Point: 93–98°C
Choose this if: Your project is in a hot climate and requires superior thermal stability to prevent sagging or bleeding.
Typical buyers: Heavy-duty roofing membrane producers, industrial mastic formulators.
Grade 115/15
Softening Point: 112–118°C
Choose this if: You need maximum hardness and heat resistance for specialized industrial applications.
Typical buyers: Electrical insulation manufacturers, high-temperature sealant producers.
Key Notes
- Softening Point: Indicates heat resistance. Higher values = better performance in hot climates.
- Penetration: Measures hardness. Lower penetration = harder bitumen.
- Ductility: Limited in oxidized bitumen due to rigidity, but sufficient for industrial use.
- All values are typical or required ranges. Exact values per batch available in Certificate of Analysis (CoA).
- Pre-shipment inspection by SGS conducted for every shipment. Reports provided.
Frequently Asked Questions (FAQ)
The first number is the minimum softening point in °C (e.g., 85°C), and the second is the mid-point of the penetration range in 0.1 mm (e.g., 25, meaning 20–30).
Oxidized Bitumen is air-blown at high temperatures, making it harder, with a higher softening point and less temperature susceptibility, ideal for waterproofing rather than road paving.
Minimum order is 200 MT per shipment, packed in 25 kg kraft cartons/bags or 1000 kg heavy-duty carton blocks.
Store in original packaging in a cool, dry, well-ventilated area on wooden pallets. Shelf life is typically 12–24 months.
Grade 95/25 or 115/15 is recommended due to higher softening points, preventing softening or bleeding under extreme heat.
