Bitumen 95/25

Bitumen 95/25

Bitumen 95/25 is a high-quality oxidized bitumen, known for its excellent hardness, thermal stability, and superior waterproofing properties. With a softening point of approximately 95°C and a penetration value of 25 dmm (tenths of a millimeter), it offers exceptional resistance to deformation, even under high temperatures and heavy loads. This grade of bitumen is specifically formulated for industrial applications where durability and reliability are critical. Its versatility also allows it to be used in a variety of other sectors, including the automotive and construction industries, for sealing and bonding purposes.

Common uses of Bitumen 95/25 include manufacturing roofing felts, waterproofing membranes, pipe coatings, and protective coatings for various structures. Its ability to withstand chemical exposure and resist water infiltration makes it ideal for applications in harsh environments. Additionally, its high softening point ensures excellent performance in regions with extreme temperature fluctuations. Bitumen 95/25’s resistance to aging and oxidation further enhances its long-term stability and performance. Produced through advanced oxidation processes, Bitumen 95/25 meets international quality standards, making it a trusted material for industrial and construction projects that demand long-lasting and efficient solutions. Its combination of strength, flexibility, and resistance to environmental stressors makes it a versatile and indispensable product in many industries.
