Bitumen 75/25: Versatile Solution for Heavy-Duty Construction Needs

Bitumen 75/25: Outstanding Reliability and Versatility for Industrial Applications

For industrial projects that require high durability and dependable performance, Bitumen 75/25 offers an unmatched combination of strength, resilience, and adaptability. As one of the most popular oxidized bitumen grades, 75/25 provides superior protection and longevity, making it a trusted choice for engineers, contractors, and manufacturers worldwide.

Technical Properties of Bitumen 75/25

Bitumen 75/25 is manufactured through an advanced oxidation process, transforming standard bitumen into a more stable, elastic, and robust material. This grade is defined by its softening point of 75°C and penetration value of 25 dmm (deci-millimeters), providing a balanced profile that supports a wide range of demanding industrial uses.

Core Properties Include:

• Moderate Softening Point (75°C): Enables the bitumen to remain stable in both hot and moderate climates, preventing flow or deformation under heat.

• Low Penetration (25 dmm): Ensures the product remains firm, increasing load-bearing capacity and structural integrity.

• Excellent Water Resistance: Prevents moisture intrusion and supports long-term waterproofing, even in harsh environments.

• Good Chemical Resistance: Protects against industrial chemicals, alkalis, acids, and salts—ideal for challenging sites.

• Adhesive Strength: Bonds efficiently to a variety of substrates, ensuring reliable sealing, coating, and binding.

• Oxidative Stability: Maintains key performance features, even after years of environmental exposure.

Industrial Applications of Bitumen 75/25

The unique combination of properties in 75/25 makes it a versatile solution for multiple sectors:

• Roofing and Waterproofing: Widely used as a binder and coating for roofing membranes, felts, and vapor barriers, 75/25 delivers reliable waterproofing and UV protection for commercial and industrial roofs.

• Pipe and Steel Coating: Acts as a protective layer on pipelines, tanks, and steel structures, providing corrosion resistance against water, chemicals, and aggressive soils.

• Expansion Joint Fillers: The stability of 75/25 makes it an excellent filler for road, bridge, and building joints, ensuring long-lasting performance under thermal and mechanical movement.

• Adhesives and Mastics: A core ingredient in the production of adhesives, mastics, and sealants for construction, automotive, and electrical applications.

• Battery Sealants and Electrical Insulation: Used in the electrical industry for its dielectric properties and stability, especially in battery manufacturing and cable insulation.

• Damp-proof Courses (DPC): Serves as a protective layer in foundation damp-proofing to block moisture from entering building structures.

Manufacturing Process of Bitumen 75/25 at basekim

Producing Bitumen 75/25 is a highly controlled process, designed to guarantee consistent quality and technical performance:

1. Base Selection: High-quality vacuum residue or penetration-grade bitumen is selected as the feedstock.

2. Heating: The raw material is heated in specialized reactors to a controlled temperature (230–260°C).

3. Air Blowing: Air is introduced to the molten bitumen, triggering oxidation and polymerization that create the final oxidized structure.

4. Property Testing: The material is continuously sampled and tested to ensure the correct softening point (75°C) and penetration value (25 dmm) are achieved.

5. Final Processing: The finished 75/25 is cooled and transferred to packing units for delivery.
