Oxidized
Bitumen 90/10
Petra Oil’s Oxidized Bitumen 90/10 is a high-performance, semi-solid binder produced through a controlled air-blowing process. With a softening point of 90°C and a penetration value of 10 dmm at 25°C, this grade offers exceptional rigidity and thermal stability, making it ideal for applications requiring minimal deformation under heat.
Manufactured in compliance with ASTM D36 and D5 standards, Oxidized Bitumen 90/10 is widely used in roofing membranes, waterproofing systems, pipe coatings, and industrial adhesives. Its high flash point of 250°C ensures safety during handling and application.
Key Specifications:
- Softening Point: 90°C
- Penetration: 10 dmm at 25°C
- Flash Point: ≥250°C
- Solubility in CS₂: ≥99%
- Ductility: ≥1.5 cm at 25°C
- Loss on Heating: ≤0.2%
Main Applications:
- Roofing Membranes: Provides durable waterproofing for flat and sloped roofs.
- Pipe Coatings: Offers corrosion resistance for underground and marine pipelines.
- Industrial Adhesives: Serves as a base for adhesives in construction and manufacturing.
- Waterproofing Systems: Used in damp-proofing and moisture barrier applications.
Key Benefits:
- High Rigidity: Maintains structural integrity under high temperatures.
