Oxidized

Bitumen 105/15

Petra Oil’s Oxidized Bitumen 105/15 is a durable, rigid oxidized bitumen designed for heavy-duty industrial and construction use. With a softening point of 105°C and a low penetration value of 15 dmm, this grade provides enhanced stiffness and high-temperature resistance, ideal for applications requiring minimal deformation under stress and long-term exposure to heat.

 

Bitumen 105/15 is especially suitable for environments that experience prolonged thermal load or where a solid, non-deforming waterproofing or sealing layer is required. It is commonly used in roofing sheets, joint sealing compounds, anti-vibration pads, and chemical-resistant coatings.

Produced through an air-blowing process under strict quality control, this grade meets international ASTM D36 and D5 standards and delivers stable, repeatable results in the field.

 

Key Specifications:

  • Grade: Oxidized Bitumen 105/15
  • Softening Point: ~105°C
  • Penetration: ~15 dmm at 25°C
  • Standard Compliance: ASTM D36 / ASTM D5
  • Form: Solid at room temperature

Main Applications:

  • Roofing and Industrial Sheeting: Used in membrane production for waterproof and UV-resistant roofs.
  • Sealing and Insulation in HVAC and Pipeline Systems: Provides heat and moisture barriers.
  • Vibration Dampening in Machinery Foundations: Reduces mechanical stress and enhances equipment life.
  • Bituminous Paints and Protective Coatings: Offers chemical resistance and long-term surface protection.

Key Benefits:

  • High Thermal Resistance: Performs consistently in high-heat applications without softening.
  • Low Penetration, High Rigidity: Suitable for load-bearing and stress-resilient sealing.
  • Long-Term Structural Integrity: Reduces degradation and material fatigue over time.
  • Versatile and Easy to Process: Can be melted and applied with standard heating tools and methods.
