Oxidized
Bitumen 90/15
Petra Oil’s Oxidized Bitumen 90/15 is a firm-grade industrial bitumen developed for demanding applications that require excellent shape retention, low penetration, and high softening point. With a softening point of 90°C and a penetration value of 15 dmm, Bitumen 90/15 is specifically formulated for use in environments that experience sustained heat and load conditions.
Commonly used in waterproofing, heavy-duty coatings, and road construction products, Bitumen 90/15 provides strong adhesion, chemical resistance, and thermal durability. It performs exceptionally well in structural joint sealing, industrial insulation, and roofing products exposed to high temperatures and mechanical stress. Bitumen 90/15 is manufactured to meet ASTM D36 and D5 standards and is compatible with automated and manual application methods.
Key Specifications:
- Softening Point: ~90°C
- Penetration: ~15 dmm at 25°C
- Standard Compliance: ASTM D36 / D5
- Form: Hard solid (requires heating for application)
Main Applications:
- Industrial roofing membranes
- Expansion joint sealants and crack fillers
- Protective coatings for steel and concrete structures
