FAQ: What is Oxidized Bitumen 90/10?

What is Oxidized Bitumen 90/10?

🧪 Blown Asphalt 90/10 is a very hard, air-blown bitumen. The “90” refers to its softening point of 90°C, while “10” represents its penetration value of 10 (1/10 mm). It is one of the hardest grades available. Engineers often use it where maximum thermal resistance and surface rigidity are essential.

What are the main applications of Oxidized Bitumen 90/10?

🏭 Blown Asphalt 90/10 is ideal for underwater pipeline coatings, chemical tank lining, electrical cable protection, and steel structure sealing. Its strength and heat stability make it suitable for heavy-duty environments. Moreover, it provides excellent insulation and anti-corrosive properties.

Why choose 90/10 over other oxidized grades?

🔧 Oxidized Bitumen 90/10 is much harder than grades like Oxidized Bitumen 85/30 or Oxidized Bitumen 85/40. It offers minimal flexibility, but maximum durability. When a project demands long-term resistance to heat and pressure, this grade performs better than most alternatives.

Is Blown Asphalt 90/10 suitable for extreme temperatures?

🌡️ Yes, Oxidized Bitumen 90/10 works very well in high-heat conditions. Its 90°C softening point ensures it won’t melt or deform even under intense sun or machinery heat. This makes it a reliable choice for industrial surfaces exposed to extreme thermal changes.

How is Oxidized Bitumen 90/10 tested for quality?

📊 Professionals measure its softening point, penetration, ductility, and specific gravity. These tests follow standards like ASTM or EN. Accurate testing helps ensure the product performs consistently in demanding industrial settings.
