Oxidized
Bitumen 90/40
Petra Oil’s Oxidized Bitumen 90/40 is a softer oxidized bitumen designed for use in applications where enhanced flexibility and moderate thermal resistance are required. Featuring a softening point of 90°C and a penetration of 40 dmm at 25°C, Bitumen 90/40 is suitable for dynamic surfaces and structures that experience minor movement or frequent thermal cycling.
Its viscoelastic properties make it a top choice for flexible sealing compounds, expansion joints, damp-proofing layers, and other industrial applications that demand elasticity without sacrificing resistance to environmental factors. This bitumen grade can be easily heated, poured, and applied with conventional tools and is known for its strong bonding to concrete, metals, and masonry. Manufactured according to ASTM D36 and D5, Bitumen 90/40 ensures consistent quality and process efficiency across a range of construction and industrial processes.
