FAQ: What is Oxidized Bitumen 150/5? Uses & Specifications

Oxidized Bitumen 150/5 (also known as Blown Asphalt 150/5) is a premium, highly specialized hard grade of asphalt. It is manufactured by blowing hot air through penetration-grade bitumen under strictly controlled temperature and pressure conditions.

The nomenclature of this grade directly reflects its two core physical properties: it features a softening point of approximately 150°C and a penetration value of 5 dmm. This molecular alteration gives the material exceptional thermal stability, making it one of the hardest and most heat-resistant grades available in the international market.

Solubility in TCEASTM D4
99% min
Verifies that the bitumen is almost entirely pure and free from inorganic mineral impurities or unrefined sludge.

Primary Applications of Blown Asphalt 150/5

Due to its high softening point and low penetration, Oxidized Bitumen 150/5 is engineered for heavy-duty industrial environments where standard penetration bitumen would lose structural integrity.

1. Oil & Gas Infrastructure

  • Underground Pipe Coating: Forms a robust, anti-corrosive, and moisture-proof protective barrier for steel pipelines.

2. Construction & Roofing

  • Waterproofing Membranes: Acts as a core ingredient in manufacturing premium roofing felts and sealing compounds that resist intense solar radiation without sagging.

3. Electrical & Automotive Industries

  • Cable Insulation: Provides dielectric properties for sealing electrical joint compounds.
  • Soundproofing: Utilized for high-density sound dampening and vibration-absorbing sheets.

💡 Technical Procurement Tip for B2B Buyers

Oxidized Bitumen 150/5 requires professional high-temperature heating equipment to reach its application viscosity. Due to its low ductility, it becomes highly rigid when cooled; therefore, for infrastructure projects in extreme winter climates, ensure the application design accounts for this structural stiffness to prevent brittle cracking under mechanical stress.
