bitumen R90/15

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 R90/15 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 R90/15 by arranging some international inspectors to check the quality and quantity of the bitumen R90/15 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

Oxidised asphalt R90/15 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, coating, insulating and impregnating agent, make rubber and plastic products. The blown asphalt R90/15 products are for paving, roofing; 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 asphalt R90/15 include roofing, pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing.

Specification

The oxidized bitumen R90/15 should be heated double temperature against the softening point to support have flow and viscosity. To use oxidized bitumen R90/15, surfaces must be dry, clean and after loose particles, formwork, curing products, irregularities, slurries, etc.
Storage and handling of oxidized bitumen R90/15: Oxidized bitumen R90/15 has 10 years validity with multi-time heating and cooling. Please refer to MSDS for more information.
Guaranty/warranty of blown bitumen R90/15: ATDM guaranty the quality of blown bitumen R90/15 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.
