Oxidized Bitumen 95/25 Description
Oxidized Bitumen 95/25 is Semi Solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business. Oxidized bitumen95/25 is based on petroleum bitumen which is made by oxidized bitumen 60/70 by very hot air. The numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value is the degrees Centigrade measured by the Ring and Ball method as determined by ASTM D36. The penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.
oxidized Bitumen is industrial bitumen which is dark, petroleum residue modified by the oxidation process. Oxidized Bitumen is produced by passing air through bitumen under controlled temperature conditions. Its consistency ranges from highly viscous to solid. Blown bitumen grade has technical advantages such as durability, flexibility, water-resistant and chemical stability. There is a different grade of blown bitumen.
Oxidized Bitumen 95/25 Applications
Oxidized Bitumen 95/25 is widely used as an anti-slip layer compound in the piling industry, for the manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts and undercarriage sealant in the automotive industry, electric cable joint protection, joint filling compound, carpet-backing, corrosion protection, acoustic panels, chemical, fuel, Manufacture of paints, sealant compound, and many others. Also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for the oil & gas pipeline joints. Further, Oxidized Bitumen is used in the manufacture of bituminous marine mastic, which is required for the oil and gas pipeline joints.
- Oxidized bitumen is used as a sealing of expansion joints.
- Oxidized bitumen is used as a repair of joints or cracks.
- Oxidized bitumen is used as a fixation of parquet floors.
- Oxidized bitumen is used as an adhesive to be used in thermal insulation.
- Oxidized bitumen is used as a repair of unexposed cracks.
- Oxidized bitumen is used as bonding of wet briquettes
- Oxidized bitumen is used in various industries like roofing, isolation, insulation flooring, mastics, pipe coatings, electrical applications.
Technical Advantages of Oxidized Bitumen 95/25
- Chemical Stability
Compared to paving grade bitumen:
- Reduced temperature susceptibility
- Exhibits a more ‘solid’ nature at ambient temperatures
- High penetration index
Storage/handling of oxidized bitumen 95/25
bitumen 95/25 has 10 years validity with multi-time heating and cooling, please refer to MSDS.
Packing of Blown Asphalt 95/25
Various pickings are available for customer’s purpose and conveniences. oxidized bitumen 95/25 in various packing including Kraft bag, meltable plastic bag, drum, and bulk bitumen 95/25 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. oxidized bitumen 95/25 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The bitumen grade 95/25 means the softening point is 95°c and penetration is 15 desi millimeter is produced in compliance and conformity with ASTM standard and meets the following specification.
