High Softening Point with Low Penetration
PN-OB11515 is manufactured by controlled air blowing of selected petroleum bitumen feedstock. The process develops a firmer material with a higher softening point and lower penetration than conventional paving grades, supporting thermal stability, reduced flow, and good shape retention in properly formulated industrial systems.
The grade is intended for professional formulation and processing. Final suitability depends on compatibility with other raw materials, heating and mixing controls, application method, service temperature, substrate condition, and the performance requirements of the finished product.
Key Product Attributes
The following attributes summarize the grade-specific performance profile stated in the product TDS.
High Thermal Stability
A 110–120°C softening-point range supports improved resistance to flow and deformation at elevated service temperatures.
Firm Body
A low 10–20 penetration range provides a hard, stable consistency with good sag resistance in suitable formulations.
Water Resistance
The bituminous matrix supports durable sealing and moisture resistance when correctly formulated and applied.
Controlled Oxidation
Managed air-blowing and production controls support repeatable grade quality and predictable processing behavior.
High Solubility
A minimum solubility specification of 99.0% by mass supports a low level of insoluble material.
Flexible Supply Formats
Meltable bags, kraft bags, cartons, steel drums, and bulk hot loading support different processing and logistics requirements.

The agreed commercial specification and applicable contractual documentation govern supply. For critical applications, compatibility, processing conditions, and finished-product performance should be confirmed under actual service conditions.
Selecting Oxidized Bitumen 115/15
Grade selection should consider the required softening point, penetration, application temperature, finished-product flexibility, sag resistance, substrate, installation method, and expected service conditions.
PN-OB11515 is generally selected where high-temperature shape stability and a firm binder body are more important than low-temperature flexibility. Laboratory trials should verify compatibility with fillers, polymers, solvents, fibres, and other formulation components.

Storage, Heating, Handling, and Transport
The current Safety Data Sheet must be reviewed before storage, melting, transfer, loading, transport, or use.
Storage and Temperature Control
- Store packaged product in a dry, covered area protected from water and contamination.
- Keep the product away from direct flame and strong oxidizing agents.
- Use indirect, uniform heating and avoid local overheating or flame impingement.
- Use the lowest practical processing temperature.
- Typical handling or application temperatures may fall within 180–230°C depending on equipment and end use.
- Unless a validated procedure states otherwise, keep prolonged storage and routine handling below 200°C and avoid temperatures above 230°C.
Personal Protection and Ventilation
- Molten oxidized bitumen can cause severe thermal burns.
- Use heat-resistant gloves, protective clothing, safety footwear, and full eye and face protection.
- Provide local exhaust and general ventilation during melting, mixing, loading, and application.
- Heating may release irritating fumes and hydrogen sulphide, particularly in tanks and confined spaces.
- Monitor oxygen and hydrogen sulphide before confined-space entry and use a formal permit and rescue system.
Critical water-contact hazard
Water or other liquids contacting molten bitumen can cause violent eruption, foaming, and splashing. Keep tanks, kettles, lines, containers, and feed materials dry.
Transport classification
Ambient-temperature packed product is generally not regulated as dangerous goods when shipped as a solid or semi-solid. Molten product transported at or above 100°C and below its flash point may be classified as UN 3257, Elevated Temperature Liquid, N.O.S. (Bitumen), Class 9, Packing Group III. Confirm the current modal and destination requirements before shipment.
