Whether you need drums, Kraft bags, or carton box packing, Raha Oil delivers consistent, ASTM-tested Oxidized Bitumen 90/15 backed by full quality documentation for every shipment.
Applications of Oxidized Bitumen 90/15
Oxidized Bitumen 90/15 is widely used across construction, industrial, and specialty applications:
Construction and Waterproofing: Roofing felts and membranes, foundation damp-proofing, joint filling, and sealing saw cuts and joints where movement is minimal.
Industrial and Protective Coatings: Pipe coating and corrosion protection, bituminous marine mastic for oil and gas pipeline joints, asphalt-based paints, mastics, and damp-proofing.
Specialty Applications: Anti-slip layer compound in the piling industry, sound-dampening felts, carpet-backing, acoustic panels, and electrical cable joint protection.
Automotive Industry: Vehicle undercoating, providing excellent waterproofing, dust protection, and noise reduction.
Beyond construction, this grade is also used in chemical, fuel, paint, lacquer, varnish, paper-pulp-board, and textile processing industries, as well as in road construction, pavement repair, and general civil works, including adhesives, dust-binding agents, and raw material for rubber and plastic products.
Oxidized Bitumen 90/15 vs. Other Oxidized Grades
Oxidized Bitumen 90/15 sits among the harder grades in the Oxidized Bitumen family, with a low penetration range (10–20) similar to 105/15 or 90/10, but with a lower softening point (85–95°C) compared to 105/15 or 115/15. This combination gives it strong rigidity while remaining slightly more workable than the highest-softening-point grades, making it a practical choice for applications needing both hardness and manageable processing.
Storage and Handling Recommendations
Oxidized Bitumen 90/15 should be stored in a cool, dry area away from direct sunlight and open flames. Its high softening point allows it to remain solid and stable at ambient temperature, simplifying long-term storage. Before heating, the material should always be broken into smaller pieces to promote even heat distribution and avoid localized overheating, which can compromise both safety and product quality.
Why Oxidized Bitumen 90/15 Is Preferred for Marine and Pipeline Applications
The combination of low penetration and high softening point makes Oxidized Bitumen 90/15 particularly effective as a base material for bituminous marine mastic used in oil and gas pipeline joint sealing. Its rigidity and resistance to deformation under pressure make it well-suited to demanding offshore and industrial environments where long-term durability is critical.
Frequently Asked Questions - FAQ
It is used mainly in roofing, waterproofing, pipe coating, automotive undercoating, and bituminous marine mastic for pipeline joints.
Oxidized Bitumen 90/15 has a softening point of 85–95°C and a penetration value of 10–20 (0.1 mm), as confirmed by ASTM D36 and ASTM D5 testing.
It should be broken into pieces and heated gradually, not exceeding the maximum safe handling temperature of 230°C, to avoid localized overheating.
Steel drums, Kraft/polyamide bags, carton boxes, and jumbo bags (upon request) are available.
