What is Oxidized Bitumen 105/15?
Oxidized Bitumen 105/15, or Blown Asphalt 105/15, is a semi-solid bitumen material produced by blowing hot bitumen with air. This oxidative process increases the softening point of the product and decreases the penetration value, making it more hard and heat-resistant. With a softening point of approximately 105°C and penetration of 10 to 20 dmm, it is most appropriate for waterproofing, roofing, insulation, and industrial applications requiring both strength and flexibility.
Production Process
The bitumen is first heated and charged to a blowing column below liquid level. Air is blown from the bottom of the column, stirring the bitumen and bringing more surface area to reaction. This causes oxidation and changes the structure of the bitumen, enhancing its mechanical and thermal properties. Water and steam are atomized into the vapor space above the bitumen to cool vapors and control foaming.
Applications
Oxidized Bitumen 105/15 has broad application across a variety of industries:
Construction: Waterproofing membranes, roof felts, joint sealants, crack sealing, and pavement repair
Automotive: Sealants for undercarriage, and vibration-dampening felts
Electrical: Insulation compounds, cable jointing protection
Industrial: Adhesives, corrosion-resistance coatings, acoustic panels, and protection paints
Packaging & Materials: Carpet backing, pulp board coating, and textile treatment
Storage & Handling
Bitumen 105/15 should be stored in a dry, cool, and ventilated area away from sunlight and fire sources. Solid blocks, drums, or bags are normally delivered. Indirect heat means like oil-jacketed kettles should be employed in melting and handling it, and temperature controlled not to emit fumes. Personal protective clothing like heat-resistant gloves, goggles, and protective clothes should be worn all the time.
Health & Safety
Not found to be very hazardous, hot oxidized bitumen can cause severe burns and lung irritation. Ventilation must be exercised when applying. Spills need to be wiped off with solvents like kerosene with safety precautions because it is flammable. Safe handling and emergency procedures need to be instructed to personnel.
Comparison: 105/15 vs 115/15
Oxidized Bitumen 105/15 and 115/15 differ mainly in their softening points, penetration values, and ideal applications. Bitumen 105/15 has a lower softening point of around 90°C and higher penetration, making it more flexible and suitable for general roofing and waterproofing tasks.
In contrast, Bitumen 115/15 softens at a higher temperature (about 105°C) and has lower penetration, making it stiffer and ideal for hot climates and heavy-duty applications like pipe coatings. Overall, 105/15 offers higher flexibility, while 115/15 provides greater thermal resistance and moderate flexibility.
