Oxidized Bitumen 90/10 (Blown Asphalt 90/10) – Medium-Hard Bitumen for Waterproofing and Industrial Use
Description:
Oxidized Bitumen 90/10 is a semi-hard, high-durability bitumen produced by air-blowing penetration-grade bitumen under controlled conditions. It has a balanced softening point and penetration value, making it suitable for applications requiring flexibility and weather resistance.
Uses:
Roofing & Waterproofing: Built-up roofing systems, waterproof membranes, and felts.
Pavement Maintenance: Crack sealing and joint filling.
Industrial Coatings: Pipe anti-corrosion coatings, tank linings, and mastic asphalt.
Adhesives & Sealants: Bituminous tapes, bonding agents, and expansion joints.
Electrical Insulation: Cable jacketing and bituminous paints.
Packing & Shipping:
- Packing: 25 kg kraft bags, 50 kg poly-lined bags, or steel drums (180-200 kg).
- Bulk: 1-ton pallets (meltable blocks) or customized packaging.
- Shipping: Transported by sea (containerized) or land (truck/rail), stored away from heat and moisture.
