Oxidized bitumen 90/15
Description of oxidized bitumen 90/15
At the bitumen production reactor, during the air acting, the mixture of the two Vacuum Bottom (VB) and Vacuum Silas (VS) feedstock is put under a special degree of pressure and temperature between 200-300˚C of which the hydrogen atoms content in bitumen molecular oxidize to oxygen of air, and obtains with higher hydrocarbons polymerization reaction that has lower penetration and higher softening points than the primary pure bitumen. This kind of bitumen 90/15 has the softening point of 90 and permeability of 15.
Oxidized bitumen is a specially formulated plastic for construction. Oxidized bitumen characterized by being a product of great thermal amplitude. Oxidized bitumen has the flexibility to cold, has no sag at high temperatures and has good adhesion. It can be applied in any kind of work. Oxidized bitumen is available in the different grade.
RABIT (RAHA BITUMEN) Company guaranty the quality of RABIT Oxidized bitumen 90/15 with the arrangement of the international inspector to check quality and quantity of the bitumen 90/15 during the loading to the vessel and controlling the production by QC by batch test report before shipping. RAHA Company guarantees the quality to meet with ASTM.
Uses of oxidized bitumen 90/15
Oxidized bitumen 90/15 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 90/15 products are for paving. also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf; typical uses for oxidized bitumen 90/15 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 90/15 is using insulation and isolation bitumen membrane sheet. Also, Car undercoating Automobile industry is specially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dust proof and noise proof for automobile undercoating.
Application of oxidized bitumen 90/15
The Oxidized bitumen 90/15 should be heated double temperature against the softening point to be able to have flow and viscosity. To use oxidized bitumen 90/15, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.
Storage/handling of oxidized bitumen 90/15
Bitumen 90/15 has 10 years validity with multi-time heating and cooling, please refer to MSDS.
Packing of oxidized bitumen 90/15
Various pickings are available for customer’s purpose and conveniences. RABIT CO is the manufacturer of bitumen 90/15 in various packing including Kraft bag, meltable plastic bag, drum, and bulk oxidized bitumen 90/15 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. RABIT oxidized bitumen 90/15 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The bitumen grade 90/15 means the softening point is 90°c and penetration is 15 desi millimeter is produced in compliance and conformity with ASTM standard and meets the following specification.
