Oxidized Bitumen 115/15: The Ultimate Solution for Reliable Roofing and Pipe Coating

Why Oxidized Bitumen 115/15 Surpasses Conventional Grades

Industrial projects demand materials that can withstand extreme conditions and deliver consistent, long-lasting results. Oxidized Bitumen 115/15 offers precisely that—a highly engineered bitumen with exceptional thermal stability, resilience, and waterproofing performance. By choosing Oxidized Bitumen 115/15, businesses gain the peace of mind that comes from reliable quality and minimized downtime, even in the toughest environments.

Technical Properties of Oxidized Bitumen 115/15

Oxidized Bitumen 115/15 is produced via controlled air-blowing of refined bitumen at elevated temperatures. This process creates a dense, solid material with a softening point of 115°C and a penetration value of 15 dmm, which distinguishes it from softer and less stable grades.

Key properties include:

• High Softening Point (115°C): Maintains stability in hot climates, industrial roofs, and asphalt mixing, reducing risk of flow or deformation.

• Low Penetration (15 dmm): Guarantees a rigid, durable structure with high load-bearing capacity and minimal deformation.

• Excellent Oxidation Stability: Resistant to environmental aging, ensuring consistent performance over the lifecycle of the structure.

• Superior Adhesion: Bonds efficiently to a variety of surfaces, including metal, concrete, and insulation boards.

• Chemical and Water Resistance: Provides robust protection against acids, alkalis, industrial effluents, and water ingress.

Industrial Applications of Oxidized Bitumen 115/15

The advanced properties of Oxidized 115/15 make it the go-to choice for a range of critical infrastructure and industrial applications:

• Roofing Felts and Membranes: Used as a binder and coating, Oxidized 115/15 delivers strong waterproofing and UV protection for flat and sloped roofs.

• Damp-Proofing in Construction: Essential in preventing moisture migration in foundations, basements, bridges, and tunnels.

• Pipeline and Steel Protection: Acts as a corrosion-resistant coating for pipelines, steel structures, and tanks exposed to aggressive soils or chemicals.

• Electrical Components: Serves as a dielectric sealant for capacitors, cables, and battery casings, offering superior insulation.

• Adhesives and Mastics: Core component in the formulation of high-strength adhesives, mastics, and sealants for industrial assemblies.

• Expansion Joint Fillers: The rigidity and stability of Oxidized 115/15 make it ideal for bridge joints and pavement seams that must withstand constant stress and movement.

Manufacturing Process: The Science Behind Oxidized Bitumen 115/15

The production of 115/15 follows a tightly controlled procedure to guarantee precise technical characteristics:

1. Feedstock Selection: High-grade vacuum residue or penetration bitumen is selected for its purity and chemical composition.

2. Heating: The base bitumen is heated in large reactors to between 240°C and 300°C.

3. Air Oxidation: Air is blown through the liquid bitumen, promoting polymerization and increasing the asphaltene content. This results in the signature high softening point and low penetration.

4. Process Monitoring: Continuous lab analysis ensures the product achieves a softening point of 115°C and a penetration value of 15 dmm, meeting strict industrial standards.

5. Final Processing: The finished Oxidized Bitumen 115/15 is cooled and transferred to packaging units for dispatch.

Packaging and Delivery Solutions

Oxidized Bitumen 115/15 is offered in multiple packaging formats to facilitate safe handling, transportation, and on-site application:

• Steel Drums: The most popular format, offering 180–200 kg per drum for easy handling and global shipping.

• Meltable Bags: Polyethylene bags (25–50 kg) that can be fed directly into mixing equipment—reducing waste and contamination.

• Jumbo Bags: 500–1000 kg big bags designed for high-volume projects.

• Custom Solutions: Packaging can be customized based on project scale, climate, and logistical requirements.

Reliable international logistics ensure prompt delivery to major project sites, with all necessary safety and export documentation.
