Oxidized Bitumen 85/30 Supplier

Oxidized Bitumen 85/30 for Industrial and Waterproofing Applications

Oxidized Bitumen 85/30 is a semi-solid, air-blown bitumen widely used in industries that require high resistance to heat, pressure, and environmental conditions. It is produced through a controlled oxidation process that transforms standard bitumen into a more durable and structurally stable material.

This grade is specifically suitable for applications where maintaining shape, resisting deformation, and ensuring long-term waterproofing performance are critical.

Where Oxidized Bitumen 85/30 is Used

Roofing and Waterproofing Systems

One of the main uses of Oxidized Bitumen 85/30 is in roofing and waterproofing. It is commonly applied in flat roofs, basements, and concrete structures where water resistance is essential.

Unlike softer bitumen grades, it does not easily soften under heat, which helps prevent leakage and structural damage over time.

Production of Roofing Membranes

This grade is widely used in the manufacturing of waterproofing membranes such as APP modified membranes and roofing felt.

Its relatively hard structure ensures that the final product remains stable even in high-temperature environments.

Pipe Coating and Corrosion Protection

Oxidized Bitumen 85/30 is used as a protective coating for pipelines in oil, gas, and water industries.

It creates a strong barrier against moisture, soil conditions, and environmental factors, helping extend the lifespan of metal pipes and reducing maintenance costs.

Joint Sealing and Industrial Applications

It is also used for filling joints and sealing cracks in construction and industrial environments.

This grade is ideal for areas where rigidity and durability are more important than flexibility, especially in concrete structures and industrial floors.

Electrical and Insulation Applications

Due to its insulating properties, Oxidized Bitumen 85/30 is used in electrical applications such as cable filling and insulation layers.

It provides thermal resistance and protects internal components from external damage.

Why This Grade is Chosen in Real Projects

In practice, Oxidized Bitumen 85/30 is selected when the project requires a material that can withstand harsh conditions without losing its structure.

It performs especially well in environments exposed to heat, pressure, and outdoor conditions, making it a reliable option for long-term industrial use.

Packing and Supply

This product is typically supplied in different packing options depending on project requirements, including small bags and bulk packaging.

It is ready for export to various international markets with flexible delivery options and standard export documentation.
