FAQ: What is Oxidized Bitumen 90/15?

❓ What is Oxidized Bitumen 90/15?

🧪 Blown Asphalt 90/15 is a hard, semi-solid bitumen created by blowing air through standard bitumen. It reaches a softening point of 90°C and has a penetration value of 15. Because of its durability and heat resistance, it suits demanding industrial applications.

❓ Where can you use Oxidized Bitumen 90/15?

🏗️ Blown Asphalt 90/15 performs well in roofing systems, steel coatings, pipe insulation, and chemical containment. Its strong heat resistance helps prevent softening in hot environments. Furthermore, its hardness ensures long-term stability.

❓ How does 90/15 compare to other grades?

🔍 Compared to 90/10, it offers slightly more flexibility while maintaining excellent durability. Unlike softer grades such as 85/25, it holds firm under higher temperatures. Therefore, it works well in applications that need a balance of strength and moderate movement.

❓ Can it withstand long-term heat exposure?

🌡️ Yes, it stays stable in high-heat environments, including direct sunlight and industrial processes. Its high softening point ensures it doesn’t melt or crack. As a result, it provides reliable performance for structures exposed to extreme temperatures.

❓ How do you test the quality of Oxidized Bitumen 90/15?

📊 Experts use tests like penetration, softening point, and ductility analysis. These tests follow standards such as ASTM D36 and EN 13304. Reliable testing ensures consistent product quality and safe application across various industries.
