Oxidized Bitumen 85/25 for Industrial and Construction Applications

Premium Oxidized Bitumen 85/25 for Industrial and Construction Applications

Oxidized Bitumen 85/25 is a high-performance oxidized bitumen manufactured by controlled air blowing of penetration-grade bitumen under carefully monitored conditions. This process enhances its hardness, durability, and thermal resistance, making it an ideal material for industrial waterproofing, insulation, roofing, sealing, and protective coating applications.

Thanks to its balanced softening point and penetration value, Bitumen 85/25 offers excellent adhesion, long-term weather resistance, and superior performance in demanding environments. It is widely used in construction, infrastructure, and manufacturing industries where reliable waterproofing and protection are essential.

What is Bitumen 85/25?

Bitumen 85/25 is an oxidized or blown bitumen with a softening point of approximately 85°C and a penetration value of 25 dmm. These characteristics provide a material that remains stable at elevated temperatures while maintaining enough flexibility for various industrial applications.

Unlike conventional penetration-grade bitumen, oxidized bitumen undergoes an air-blowing process that changes its molecular structure, improving resistance to aging, oxidation, chemicals, and environmental exposure.

Its excellent waterproofing capability and mechanical stability have made Oxidized Bitumen 85/25 a preferred choice in numerous industrial sectors.
