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 degree of pressure and temperature (between 200-300˚C) of which the hydrogen atoms content in the bitumen molecules oxidized, 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 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 many different grades.
We guarantee the high quality of our oxidized bitumen 90/15 by arranging some international inspectors to check the 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. Bitumen Malaysia guarantee the quality to meet with ASTM standard.
Uses of oxidized bitumen 90/15
Oxidized bitumen 90/15 is used in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seals and repairs, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, and also to manufacture rubber and plastic products. Oxidized bitumen 90/15 products are 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 are for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. This grade of bitumen can be used for insulation and isolation in bitumen membrane sheets. It is also used in the automobile industry for car undercoating as it is proven to be an excellent water-proofing, dust proofing and also noise proofing material.
Application of oxidized bitumen 90/15
The oxidized bitumen 90/15 should be heated double temperature against the softening point to support have flow and viscosity. To use oxidized bitumen 90/15, surfaces must be dry, clean and after loose particles, formwork, curing products, irregularities, slurries, etc.
Storage and handling of oxidized bitumen 90/15
Oxidized bitumen 90/15 has 10 years validity with multi-time heating and cooling. Please refer to MSDS for more information.
Packing of oxidized bitumen 90/15
A few type of packing is available for customer’s purpose and conveniences. Bitumen Malaysia manufactures oxidized bitumen 90/15 and packed different types of packaging including in Kraft bags, meltable plastic bags, drums, and bulk. Oxidized bitumen 90/15 is a penetration-grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. Bitumen Malaysia can supply oxidized bitumen in any grade and are designated by two numbers to show the softening point and penetration ranges. The bitumen grade 90/15 means the softening point is 90 °C and penetration is 15 desi millimeters. They are produced in compliance and conformity with ASTM standard and meets the following specification.
