Oxidized Bitumen 95/25, also referred to as blown bitumen, is a semi-solid petroleum product manufactured by passing hot air through penetration grade bitumen under carefully controlled processing conditions. This oxidation process modifies the molecular structure of the base bitumen, increasing its softening point and improving its resistance to heat, aging, and environmental factors. The result is a stable and durable material suitable for a wide range of industrial and construction applications.

The grade 95/25 indicates a softening point of approximately 95°C and a penetration value of 25 (0.1 mm at 25°C). This combination provides a balanced material with moderate hardness and good flexibility, making Oxidized Bitumen 95/25 ideal for applications where both workability and thermal stability are required.

Oxidized Bitumen 95/25 is typically produced from high-quality penetration grade bitumen such as Bitumen 60/70. During production, molten bitumen is exposed to a controlled flow of hot air in oxidation reactors. Key parameters including temperature, airflow rate, and oxidation time are precisely monitored to achieve consistent physical properties and uniform quality across all production batches.

One of the main advantages of Oxidized Bitumen 95/25 is its improved thermal stability compared to conventional penetration grade bitumen. The material exhibits reduced temperature sensitivity, meaning it is less prone to softening or flowing under high ambient temperatures. This makes it suitable for use in warm climates and applications exposed to prolonged heat and sunlight.

Oxidized Bitumen 95/25 demonstrates excellent adhesion to a wide range of substrates, including concrete, metal, masonry, and bituminous surfaces. When applied, it forms a continuous, waterproof layer that effectively protects underlying structures from moisture penetration. This property makes it a reliable material for waterproofing systems and protective coatings.

In roofing applications, Oxidized Bitumen 95/25 is commonly used in the production of roofing felts, membranes, and bituminous sheets. Its ability to maintain dimensional stability and resist deformation at elevated temperatures ensures long-term performance and durability. The material’s strong bonding capability contributes to enhanced resistance against weathering and environmental stress.

For pipe coating and corrosion protection, Oxidized Bitumen 95/25 provides an effective barrier against moisture, soil chemicals, and corrosive environments. It is widely applied to steel pipelines, tanks, and industrial equipment to extend service life and reduce maintenance costs. The bituminous coating acts as a protective shield that minimizes oxidation and external corrosion.

Oxidized Bitumen 95/25 is also used in industrial insulation applications. It serves as a protective and insulating layer for storage tanks, vessels, ducts, and pipelines operating at moderate temperatures. The material helps reduce heat loss, protects insulation systems, and improves overall energy efficiency.

In the paint and coating industry, Oxidized Bitumen 95/25 is used as a base material for manufacturing bituminous paints, primers, and protective coatings. These coatings are applied to metal structures, bridges, roofs, and industrial facilities where resistance to corrosion, chemicals, and weather exposure is required. The penetration level of this grade allows for smooth application and good film formation.

The sealing and adhesive properties of Oxidized Bitumen 95/25 make it suitable for use in construction sealants, joint fillers, and crack-sealing compounds. It is commonly applied in expansion joints, pavement maintenance, and civil engineering projects where flexibility, durability, and resistance to environmental changes are essential.

Oxidized Bitumen 95/25 is also utilized in hydraulic and civil engineering works such as canal lining, foundation protection, and water containment systems. Its waterproofing capability and resistance to water pressure help prevent leakage and structural deterioration in water-related infrastructure.

For proper application, Oxidized Bitumen 95/25 should be heated gradually using suitable heating equipment to achieve the desired viscosity. Excessive overheating should be avoided to prevent degradation of the material’s properties. When applied under recommended conditions, the product delivers reliable performance and a long service life.

Storage of Oxidized Bitumen 95/25 should be in a dry, covered area, protected from direct sunlight, rain, and moisture. Proper storage conditions help preserve the product’s physical characteristics and ensure consistent quality over time. When stored correctly, the product maintains a long shelf life.

Oxidized Bitumen 95/25 is available in various packaging options to meet different logistical and project requirements, including 25 kg meltable bags, kraft bags, steel drums, jumbo bags, and bulk supply. Palletized packing is commonly used for containerized shipments, ensuring safe transportation and efficient handling during international export.

The product is manufactured in accordance with ASTM international standards and undergoes strict quality control testing, including softening point, penetration, ductility, flash point, solubility, and loss on heating. These quality checks ensure that Oxidized Bitumen 95/25 meets global specifications and delivers consistent performance.

Due to its balanced properties, durability, and cost-effectiveness, Oxidized Bitumen 95/25 is widely used in construction, industrial manufacturing, infrastructure development, and maintenance projects worldwide. It is a trusted solution for applications requiring reliable waterproofing, moderate thermal resistance, and long-term performance.
