Oxidized Bitumen 115/15 (Blown Asphalt 115/15) – High-Temperature Resistant Bitumen for Industrial Applications
Description:
Oxidized Bitumen 115/15 is a semi-hard, high-softening point bitumen produced through controlled air-blowing of vacuum-distilled bitumen. This grade offers:
- Excellent thermal stability (softening point: 110–120°C)
- Moderate penetration (10–20 dmm) for balanced flexibility
- Superior weather resistance and durability in harsh conditions
Ideal for applications requiring heat resistance, waterproofing, and structural integrity in extreme environments.
Primary Uses:
Industrial & Heavy-Duty Coatings:
- Pipe and tank anti-corrosion coatings
- Chemical-resistant linings
- High-temperature sealants
Construction & Waterproofing:
- Heavy-duty roofing membranes
- Bridge deck waterproofing
- Tunnel lining systems
Specialty Applications:
- Cable and wire insulation
- Expansion joint fillers
- Mastic asphalt for industrial flooring
Modified Bitumen Products:
- Base material for polymer-modified bitumen (PMB)
- Reinforced with fibers for added strength
Packing & Shipping:
Packaging Options:
- 200 kg new steel drums (UN-certified)
- 25 kg poly-lined kraft bags (UV-resistant)
- 1 MT bulk palletized blocks (shrink-wrapped)
Shipping & Handling:
- Bulk Shipment: Heated tankers (maintained at 160–180°C)
- Sea Freight: 20′ or 40′ containers (IMDG compliant)
- Storage: Keep in cool, dry conditions away from direct sunlight
Shelf Life: 24 months in original packaging
