    What is Bitumen 105/15?

    Bitumen 105/15 enters the ultra-hard segment of the oxidized bitumen range, with a softening point of 105–115°C and an ultra-low penetration of just 10–20 dmm.

    At this specification level, the product transcends standard construction and roofing applications and enters the domain of specialised industrial processes, high-temperature protective coatings, electrical applications, and heavy-duty industrial maintenance. 

    With a softening point exceeding 105°C, Bitumen 105/15 will not deform, flow, or lose adhesion in any operational environment that oxidized bitumen is routinely specified for — including the hottest industrial process facilities, refinery structures, and desert-region infrastructure.

    It is used as an insulating compound in electrical cable manufacturing, as a high-hardness impregnant for industrial boards, and as a protective coating in environments where temperatures, chemicals, or mechanical stresses would rapidly compromise softer grades.

    Applications of Bitumen 105/15

    Cable Insulation & Filling

    Electrical cable insulation compound and armour filling compound

    High-Temp Anti-Corrosion

    High-temperature anti-corrosion coating for refinery process piping and equipment

    Furnace Base Protection

    Advantages of Bitumen 105/15

    Bitumen 105/15 serves a wide spectrum of construction, industrial, and infrastructure 

    Extreme Heat Stability

    Softening point 105–115°C — among the highest for standard oxidized bitumen grades, suitable for the most demanding industrial thermal environments

    Maximum Hardness & Wear Resistance

    Ultra-low penetration (10–20 dmm) provides maximum hardness and abrasion resistance

    Superior Electrical Insulation

    Excellent electrical insulation properties — low dielectric constant and high surface resistivity

    Advanced Chemical Resistance

    Outstanding chemical resistance to industrial solvents, acids, alkalis, and hydrocarbon contamination

    High-Temperature Aging Resistance

    Exceptional resistance to high-temperature aging and oxidative degradation

    Low Temperature Sensitivity
