Oxidized Bitumen 75 25 in Drum

Oxidized Bitumen 75/25 is a high-quality oxidized bitumen produced by passing air through penetration-grade bitumen under controlled temperatures. This process increases the softening point while reducing penetration, resulting in a durable and thermally stable waterproofing material. Thanks to its excellent adhesion, chemical resistance, and long service life, Bitumen 75/25 is widely used in roofing systems, waterproofing membranes, pipe coating, industrial flooring, and corrosion protection.

We supply premium Bitumen 75/25 that complies with international quality standards. Our products are manufactured using carefully selected raw materials and undergo strict quality control to ensure consistent performance for industrial and construction applications worldwide.

What is Bitumen 75/25?

Bitumen 75/25 is an oxidized (blown) bitumen with a typical softening point of approximately 75°C and a penetration value around 25 dmm. These characteristics make it significantly harder than conventional paving bitumen, allowing it to perform effectively in demanding environments where higher temperature resistance and durability are essential.

Unlike penetration-grade bitumen used for road construction, Bitumen 75/25 is specifically designed for industrial applications requiring excellent waterproofing properties, strong adhesion, and resistance to environmental aging.

The controlled oxidation process enhances the material's mechanical properties without adding polymers or chemical modifiers, making it an economical and reliable solution for numerous industries.

Key Features of Bitumen 75/25

Bitumen 75/25 offers several performance advantages, including:

  • Excellent waterproofing capability
  • High softening point for superior heat resistance
  • Strong adhesion to concrete, steel, and masonry
  • Excellent resistance to moisture and corrosion
  • Good flexibility under normal service conditions
  • Long-term durability
  • High resistance to weathering and oxidation
  • Easy application after heating
  • Cost-effective waterproofing solution
  • Stable performance in various climate conditions

These properties make Bitumen 75/25 suitable for both large infrastructure projects and industrial manufacturing.

1.What is the difference between Oxidized Bitumen 75/25 and penetration-grade bitumen?

Penetration-grade bitumen is mainly used for asphalt paving, while Oxidized Bitumen 75/25 undergoes an air-blowing process that increases its softening point, hardness, and resistance to heat, making it ideal for waterproofing and industrial uses.

2.How should Oxidized Bitumen 75/25 be heated?

The product should be heated gradually using indirect heating equipment. Avoid overheating beyond the recommended application temperature to prevent excessive fumes and material degradation.

3.What is the shelf life of Oxidized Bitumen 75/25?

When stored in its original unopened packaging in a cool, dry location away from direct sunlight, the product has a shelf life of up to 10 years.
