90/15

Oxidized Bitumen 90/15, also known as Blown Asphalt 90/15, is a specialized bitumen product created by air-blowing penetration-grade bitumen. This process results in a bitumen with enhanced thermal stability, moderate hardness, and superior weather resistance, making it an excellent material for various industrial applications.

Key Properties of Oxidized Bitumen 90/15

1. Softening Point (~90°C):
   Ensures that the bitumen remains stable and functional even in high-temperature environments.

2. Moderate Penetration Value (~15 dmm):
   Balances hardness with slight flexibility, suitable for applications needing durability with minimal deformation.

3. Excellent Waterproofing:
   Prevents water and moisture penetration, ensuring effective sealing and long-lasting performance.

4. Thermal Resistance:
   Maintains stability under heat, making it ideal for use in hot environments.

5. Chemical Stability:
   Resistant to acids, alkalis, and other chemicals, ensuring durability in aggressive industrial conditions.

6. Aging and Weather Resistance:
   Performs well against UV radiation, oxidation, and other environmental stresses, offering long-term reliability.

Applications of Oxidized Bitumen 90/15

1. Roofing and Waterproofing:
   Used in waterproofing membranes for roofs and building foundations to protect against moisture and leaks.

2. Pipe Coatings:
   Provides anti-corrosion protection for underground and underwater pipes, extending their lifespan.

3. Joint Fillers and Adhesives:
   Acts as a strong binder in industrial adhesives and joint-filling applications.

4. Electrical Insulation:
   Its low conductivity makes it suitable for insulating electrical components and cables.

5. Industrial Flooring:
   Adds durability and resistance to wear, heat, and chemicals in industrial floor coatings.

6. Construction Sealants:
   Effective in sealing joints and cracks in construction projects, ensuring water and air-tight structures.
