FAQ: What is Oxidized Bitumen 105/35?

❓ What is Oxidized Bitumen 105/35?

🧪 Oxidized Bitumen 105/35 is a high-performance industrial bitumen with a softening point of 105°C and a penetration value of 35. Manufacturers produce it through air-blowing, which enhances its thermal resistance and hardens its structure. It is designed for environments where high heat and mechanical strength are critical.

❓ Where can you use Oxidized Bitumen 105/35?

🏗️ This grade performs well in waterproofing, cable sheathing, protective coatings, and roofing membranes. Its ability to withstand both high temperatures and mechanical stress makes it ideal for demanding construction and infrastructure projects. It also reduces the risk of flow or deformation.

❓ How is 105/35 different from softer grades like 90/40 or 85/25?

🔍 Unlike softer grades, 105/35 offers more rigidity and heat endurance. While flexible grades adapt to slight movement, 105/35 excels in static, high-stress applications. This makes it a top choice when projects demand consistent shape retention and thermal durability.

❓ Is Oxidized Bitumen 105/35 suitable for high-load environments?

🌡️ Yes, this grade maintains its form under both thermal and mechanical pressure. It resists sagging, softening, or cracking during temperature fluctuations. That’s why industries rely on it for long-term protection in extreme operational conditions.

❓ How do you test the quality of Oxidized Bitumen 105/35?

📊 Experts evaluate it using tests like ASTM D5 (penetration), ASTM D36 (softening point), and ASTM D113 (ductility). These tests confirm its reliability, consistency, and suitability for industrial use. Regular lab checks also ensure adherence to international performance standards.
