Oxidized Bitumen 105/15 Supplier in Turkey

Oxidized Bitumen 105/15, also known as blown asphalt 105/15 or air-blown bitumen, is a high-performance industrial material designed for applications requiring elevated thermal resistance and structural stability.

Produced through a controlled air-blowing process, this grade offers consistent quality and reliable performance in demanding industrial environments. As a Turkey-based supplier, we provide export-ready material with flexible packaging and stable supply conditions for international markets.

What is Oxidized Bitumen 105/15

Oxidized Bitumen 105/15 is manufactured by passing air through penetration-grade bitumen at high temperatures. This process increases the softening point and reduces penetration, resulting in a harder and more temperature-resistant material compared to conventional bitumen.

The designation 105/15 refers to two key properties:

• Softening point: approximately 105°C
• Penetration: approximately 15 dmm

These characteristics make it suitable for applications where heat resistance and dimensional stability are required.

Key Properties

• Softening point: 100–110°C
• Penetration: 10–20 dmm
• High thermal stability
• Strong adhesion to various substrates
• Effective moisture resistance
• Resistance to mild chemicals
• Low ductility, designed for rigid applications

Production Process

The material is produced through a controlled oxidation process under defined temperature and pressure conditions. Each batch is tested to ensure compliance with relevant international standards.

Typical production stages include:

• Selection of base bitumen
• Heating to operational temperature
• Air injection and oxidation
• Laboratory testing
• Packaging and dispatch

Applications

Due to its hardness and resistance to heat, Oxidized Bitumen 105/15 is widely used in:

• Roofing systems and waterproofing membranes
• Foundation and basement waterproofing
• Pipeline coating and corrosion protection
• Bituminous felt and industrial fabrics
• Expansion joints in concrete structures
• Industrial flooring systems
• Cable insulation and battery components
• Hydraulic and infrastructure projects

Packaging Options

Packaging can be arranged according to customer requirements and logistics conditions:

• Kraft paper bags (25 kg)
• Steel drums (approximately 180 kg)
• Jumbo bags (500–1000 kg)
• Carton boxes
• Bulk supply via heated tank containers
• Private labeling and custom packaging

Export and Supply

• Origin: Turkey
• Minimum order quantity: typically 1 MT for bagged material and 20–25 MT for bulk
• Production lead time: 3–7 working days
• Export terms: EXW, FOB, CFR, CIF
• Shipment: available to major international ports

Storage and Handling

Material should be stored in a dry and shaded environment away from direct sunlight.

• Recommended storage temperature: below 40°C
• Application temperature: typically 200–230°C
• Avoid overheating beyond recommended limits
• Use appropriate safety equipment during handling

Frequently Asked Questions

What do the numbers 105/15 indicate
The numbers refer to the softening point (105°C) and penetration value (15 dmm), which define the hardness and thermal behavior of the material.

Is oxidized bitumen the same as blown asphalt
Yes. Both terms describe the same air-blown production process.

Is this grade suitable for cold climates
This grade is primarily used in warm climates. In low temperatures, it may become brittle, and softer grades are generally preferred.

What standards does the product comply with
The material is typically tested according to ASTM and EN standards, depending on customer requirements.

What is the typical delivery time
Production usually takes between 3 to 7 working days, followed by shipping depending on the destination.
