Oxidized Bitumen 105/35 (Blown Asphalt 105/35) – Versatile Performance Grade for Industrial and Construction Applications
Description
Oxidized Bitumen 105/35 is a premium semi-soft grade produced through controlled air-blowing of vacuum-distilled bitumen. This balanced formulation features:
- Optimal softening point (100-110°C) for thermal stability
- Moderate penetration (30-40 dmm) for excellent flexibility
- Superior weathering resistance and adhesion properties
Engineered for applications requiring both durability and workability in moderate to high temperature conditions.
Key Performance Advantages
Thermal Stability: Performs reliably at sustained temperatures up to 130°C
Flexibility: Maintains integrity under thermal cycling and movement
Waterproofing Excellence: Forms impermeable barriers against moisture
Chemical Resistance: Withstands mild acids, alkalis and salts
