OXIDIZED BITUMEN
High-Performance Industrial & Waterproofing Grade
Oxidized Bitumen, also known as Blown Bitumen, is produced by passing air through penetration grade bitumen under controlled temperature conditions. This oxidation process enhances the material’s softening point, hardness, chemical stability, and temperature resistance, making it suitable for demanding industrial and construction applications.
Key Characteristics
- Higher softening point
- Increased hardness and stability
- Excellent resistance to flow at high temperatures
- Strong adhesive and sealing properties
- Low temperature sensitivity
- Improved chemical and weather resistance
- Long service life under harsh environmental conditions
Available Grades
Oxidized Bitumen is available in various grades (e.g., 85/25, 90/40, 95/25, etc.), classified based on softening point and penetration values to meet specific industrial requirements.
Applications
Oxidized Bitumen is extensively used in:
- Roofing Systems: Roofing felts, membranes, and built-up roofing layers
- Waterproofing: Foundations, basements, retaining walls, and structural protection
- Industrial Coatings: Protective coatings for pipes, tanks, and metal structures
- Sealants & Joint Fillers: Expansion joints and crack sealing
- Electrical Insulation: Cable filling compounds and insulation materials
- Mastic Asphalt Production: Flooring and heavy-duty surfaces
- Pipe Coating: Corrosion protection for underground pipelines
- Adhesives Manufacturing: Bituminous adhesives and bonding agents
- Soundproofing & Damp-Proofing Systems
Its high softening point makes it especially suitable for hot climate regions and applications exposed to elevated temperatures.
Technical Quality Parameters
Oxidized Bitumen undergoes strict quality control testing, typically including:
- Softening point test
- Penetration test
- Ductility measurement
- Flash point determination
- Loss on heating
- Solubility in solvents
- Specific gravity
Each batch is verified to ensure consistent physical and chemical properties.
