Oxidized Bitumen 150/5 (Blown Asphalt 150/5) – Ultra-Hard Specialty Grade for Extreme Conditions
Description:
Oxidized Bitumen 150/5 is an exceptionally hard, high-softening point blown bitumen produced through extended air-blowing of vacuum residue. Characterized by its extraordinary thermal stability (softening point up to 150°C) and minimal penetration, this specialty grade is engineered for applications demanding extreme heat resistance and structural integrity.
Key Characteristics:
✓ Unmatched Thermal Resistance: Performs reliably in continuous high-temperature environments (up to 180°C)
✓ Minimal Cold Flow: Maintains dimensional stability under prolonged stress
✓ Superior Weathering Resistance: Exceptional UV and oxidation resistance
✓ High Load-Bearing Capacity: Ideal for structural applications
