Oxidized Bitumen 90/10 Description
Oxidized Bitumen 90/10 (in other words, oxidized Asphalt 90/10, blown bitumen 90/10) 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 asphalt 90/10 is based on petroleum bitumen which is made by oxidized asphalt 60/70 by 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 90/10 Applications
Oxidized bitumen 90/10 uses in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The Oxidized asphalt 90/10 products are for paving. also used in asphalt-based paints for corrosion protection of metals, inlining public works structures, adhesives in electrical laminates, a base for synthetic turf; typical uses for Blown Asphalt 90/10 90/10 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Oxidized bitumen 90/10 is using the insulation and isolation bitumen membrane sheet. Also, Car undercoating Automobile industry is especially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dustproof, and noise proof for automobile undercoating.
The Blown Asphalt 90/10 90/10 should be heated double temperature against the softening point to be able to have flow and viscosity. To use Blown Asphalt 90/10 90/10, surfaces must be dry, clean, and free of loose particles, formwork, curing products, irregularities, slurry, etc.
Storage/handling of Blown Asphalt 90/10
Bitumen 90/10 has 10 years of validity with multi-time heating and cooling, please refer to MSDS.
Packing of Blown Asphalt 90/10
Various pickings are available for customer’s purpose and conveniences. bitumen 90/10 in various packing including Kraft bag, meltable plastic bag, drum, and bulk Blown Asphalt 90/10 90/10 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. Blown Asphalt 90/10 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The bitumen grade 90/10 means the softening point is 90°c and penetration is 10 desi millimeter is produced in compliance and conformity with ASTM standard and meets the following specification.
