bitumen R85/25

description

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 R85/25 has the softening point of 85 and permeability of 25.
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 R85/25 by arranging some international inspectors to check the quality and quantity of the bitumen R85/25 during the loading to the vessel and controlling the production by QC by batch test report before shipping. Bitumen Kian guarantee the quality to meet with ASTM standard.

applications

Oxidized bitumen R85/25 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 R85/25 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 R85/25 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.

Specification

The oxidized bitumen R85/25 should be heated double temperature against the softening point to support have flow and viscosity. To use oxidized bitumen R85/25, surfaces must be dry, clean and after loose particles, formwork, curing products, irregularities, slurries, etc.
Storage and handling of oxidized bitumen R85/25: Oxidized bitumen R85/25 has 10 years validity with multi-time heating and cooling. Please refer to MSDS for more information.
Guaranty/warranty of blown bitumen R85/25: ATDM guaranty the quality of blown bitumen R85/25 with arrangement of international inspector to check quality and quantity of the bitumen on each shipment during the loading to vessel and controlling the production by qc team via batch test report before shipping. ATDM guaranty the quality to meet with ASTM/EN 13304:2009.
