Oxidized bitumen 95/25:
R95/25 is a low oxidized bitumen grade. It is based on pure penetration bitumen, 60/70 grade. Manufacturing product is such that the bitumen is in contact with very hot air and is aerated. This operation is done under careful supervision and examination to obtain bitumen with the required specifications. Blown bitumen specifications are done by the ASTM method. It is an international test method. Two of the most obvious characteristics of bitumen, softening point (°C) and needle penetration (desi millimeter), are determined by two tests ASTM D36 and ASTM D5, respectively.
Oxidized bitumen or blown bitumen 95/25 is known by two properties softening point and needle penetration that which are 95 °C and 25 desi-millimeter, respectively. Moreover, there are some advantages like durability, flexibility, water-resistance and more chemical stability.
PUB-LTD manufactured Oxidized Bitumen 95/25 (or Blown Bitumen 95/25) is used in numerous industrial applications and operations. It has rubber property more than previous grades; because of its especial property in oxidization procedure. It is used in the production of especial paints, civil works, construction, road construction, roofing, facing, flooring, as anti-slip layer components, undercarriage sealant in the cars and automobile industry, in the pilling industry, electrical operations, cable coating, oil and gas pipelines coating, crack sealing, road repair operations, pulp papers, bituminous products, textile, joint filling compound, sound-reducing agent, dust proofing, waterproofing, roofing felts, lacquers, varnishes, pavements, fuel combination, and paving.
Also, it’s used as raw material for adhesive, insulation, isolation bitumen membrane sheet, chemical, especial bitumen-based paints and colors to protect metal structures from corrosion, hydraulic applications and operations, Portland cement pavements, as a base for synthetic turf, producing rubber and plastic production.
Heating Bitumen in most final uses is a critical stage. Generally, the most important thing in this procedure is heat control. Temperature and heat control can affect various aspects of the product, including its quality. The safe and recommended maximum temperature is 230℃.
All Oxidized Bitumen is not hazardous at below 100℃ during shipping operations. Heating and heat transfer should be control. Without good heat transfer may cause overheating and release low flash vapors, which these unwanted side products have a higher fire risk.
Also, melted bitumen should not be left in the boiler to get cold. Because it can cause overheating and needs more positional energy. Furthermore, placement and installing any temperature and pressure monitoring and control devices are very important. Because if their placement is not true, thermometers can’t display the real temperature that it can leads to poor monitoring and thermal conductivity.
Everyone who works in Oxidized Bitumen plants should be wear gloves, masks (especial protective masks), and safety glasses. For more information, please refer to MSDS.
