The MSDS of oxidized bitumen provides the essential information about its safe handling, storage, and hazards. It specifies the chemical composition, health hazard, first aid, and precautionary measures that need to be taken for industrial use. The understanding and compliance with the MSDS ensure compliance with safety standards and create a safe working and environmental […]

What is Oxidized Bitumen 85/40? Oxidized Bitumen 85/40, also known as blown bitumen, is a semi-solid petroleum bitumen grade resulting from air-blowing asphalt flux. The flux is normally derived by oxidizing asphalt 60/70 with hot air. 85/40 is grade referring to penetration value and the softening point of the material. Softening point is carried out […]

Oxidized Bitumen 90/40, also called blown asphalt 90/40, combines a high softening point of 85 to 95 °C with a relatively soft body of 35 to 45 dmm penetration. That pairing is unusual and it is the reason the grade exists: it holds its shape in heat like a hard grade, but still tolerates the movement […]

Oxidized Bitumen 115/15, also called blown asphalt 115/15, is the hardest grade in common commercial use: a softening point of 110 to 120 °C against a penetration of just 10 to 20 dmm. It is specified where the material has to stay rigid and dimensionally stable at temperatures that would soften any other grade — electrical […]
