Bitumen 30
Bitumen 30
Bitumen 30 is the soft grade of blown bitumen with softening point of 30+5 and softening point approx. 70C and it is available in bag and drum but in summer time it is risky to take it in the bag due to leakage of bitumen 30 inside of the container. Bitumen No.30 is producing by bitumen #60 and after heating up and lost 5% of total weight the first grade of oxidized bitumen is number 30.
Uses of bitumen #30
1. For underground moisture, waterproofing works
2. For nuclear power engineering, pipeline engineering, bottom anticorrosion, asphalt production of the production
3. For waterproofing membrane, moisture-proof paper production, etc.
4. For Anti-corrosion paint and waterproof production
5. Used for road and bridge caulking use
