What is Oxidized Bitumen? Oxidized bitumen, also known as blown bitumen, is produced by passing air through penetration grades, giving it more rubbery properties than its original formula. This hard bitumen is widely used in various industries, including the piling industry, roofing felts, waterproofing, sound dampening felts, and under carriage sealant in the automotive […]
Bitumen 60/70 is a medium-hard penetration grade with a needle penetration of 60 to 70 dmm at 25 °C, tested to ASTM D5. It is the most widely exported paving grade in the world, and in warm and tropical climates it is the default binder for hot mix asphalt. ZUMRUT INT Co. supplies it in jumbo […]
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 […]
