Oxidized Bitumen 95/25 (Blown Asphalt 95/25) – Premium Multi-Purpose Bitumen for Construction and Industrial Applications
Description
Oxidized Bitumen 95/25 is a versatile semi-hard grade produced through precisely controlled air-blowing process, featuring:
- Optimal balance between hardness (softening point 90-100°C) and flexibility (penetration 20-30 dmm)
- Superior weather resistance and long-term durability
- Excellent adhesion to various substrates including concrete, metal and roofing materials
This grade is specially engineered for applications requiring both structural integrity and workability in moderate to high temperature conditions.
Key Performance Benefits
Thermal Stability: Performs reliably at continuous temperatures up to 120°C
Flexible Performance: Withstands thermal cycling and structural movement
Waterproofing Excellence: Creates impermeable moisture barriers
Chemical Resistance: Resists mild acids, alkalis and environmental salts
