Description of Oxidized Bitumen 90/10

Oxidized bitumen 90/10 is semi solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Oxidized bitumen 90/10 is based on petroleum bitumen which is made by blowing grade 60/70 bitumen by hot air. The numbers 90/10 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.

Although grade 90/10 is a very good grade, we find that our clients prefer oxidized bitumen 115/15 over other grades. This is mainly to the fact that this grade is one of the most versatile grade of oxidized bitumen in the market. 

Uses of oxidized bitumen 90/10

Oxidized bitumen 90/10 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 90/10 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 90/10 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 90/10

The oxidized bitumen 90/10 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 90/10

Oxidized bitumen 90/10 has 10 years validity with multi-time heating and cooling. Please refer to MSDS for more information.

Packing of oxidized bitumen 90/10

A few type of packing is available for customer’s purpose and conveniences. Bitumen Malaysia manufactures oxidized bitumen 90/10 and packed different types of packaging including in Kraft bags, meltable plastic bags, drums, and bulk. Oxidized bitumen 90/10 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 90/10 means the softening point is 90 °C and penetration is 10 desi millimeters. They are produced in compliance and conformity with ASTM standard and meets the following specification.
