Oxidized Bitumen, also known as Blown Bitumen, is a special grade of bitumen produced by blowing hot air into penetration grade bitumen at controlled temperatures. This process modifies the physical properties of bitumen, giving it higher softening point, lower penetration, and enhanced elasticity compared to standard paving grade bitumen. Oxidized Bitumen is widely used in roofing, waterproofing, industrial applications, and insulation materials where superior performance under high temperatures and resistance to deformation are required.
Typical properties (depending on grade such as 85/25, 90/40, 115/15, etc.):
| Specification | Value |
|---|---|
| Penetration at 25°C (0.1 mm) | 15 – 50 |
| Softening Point (R&B) | 70 – 120 °C |
| Ductility at 25°C | ≥ 5 cm |
| Flash Point (COC) | ≥ 250 °C |
| Loss on Heating (163°C, 5h) | ≤ 0.5 % |
| Solubility in Trichloroethylene | ≥ 99 % |
The exact values vary depending on the oxidized grade (e.g., 85/25, 90/40, etc.), which indicates the softening point and penetration index.
• High softening point for stability under elevated temperatures.
• Reduced penetration for improved hardness and durability.
• Excellent resistance to aging, oxidation, and weathering.
• Good flexibility and elasticity, ensuring long-term performance.
• Superior waterproofing and adhesive characteristics.
• Roofing materials such as roofing felts, shingles, and membranes.
• Waterproofing layers in construction projects.
• Pipe coating and corrosion protection.
• Electrical insulation materials.
• Industrial adhesives, paints, and sealants.
• Soundproofing and vibration damping products.
Oxidized Bitumen is available in:
• Kraft bags or polyethylene bags (25–50 kg)
• Cartons for smaller quantities
• Steel drums (180–200 kg net)
• Jumbo bags (1 MT)
• Meltable plastic bags for direct use in mixing processes
• Store in dry, cool, and shaded areas, away from direct sunlight.
• Avoid heating above 230–240°C to prevent degradation.
• Use appropriate PPE (gloves, goggles, protective clothing) during handling.
• Follow international safety standards for transportation and storage
