Oxidized Bitumen 90/15 (Blown Asphalt 90/15) – High-Strength Industrial Grade for Demanding Applications
Description
Oxidized Bitumen 90/15 is a hard, high-performance blown bitumen produced through controlled air-blowing process. This premium grade offers:
- Optimal balance of hardness (softening point 85-95°C) and strength (penetration 10-20 dmm)
- Superior durability in extreme weather conditions
- Excellent adhesion to multiple substrates
Engineered for applications requiring structural integrity and long-term performance in harsh environments.
Key Characteristics
High-Temperature Resistance: Stable up to 110°C continuous exposure
