Oxidized bitumen 150/5
Oxidized bitumen 150/5 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air. This type of bitumen is hard and breakable. Oxidized bitumen 150/5 is the semi-solid oxidized grade of petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction industries. bitumen 150/5 should be heated double temperature (200ᵒ-300ᵒC) against the softening point to be able to have flow and viscosity. Normally heating of such hard oxidized bitumen should be arranged via hot oil by circulation inside of the isolated jacket. Bitumen oxide 150/5 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. SBI oxidized bitumen 150/5 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The oxidized bitumen 150/5 means the softening point is 150°c and penetration is 15 desi millimeter is produced in compliance and conformity with ASTM standard.
SBI Company guaranty the quality of SBI 150/5 with the arrangement of the international inspector to check quality and quantity of the SBI 150/5 during the loading to the vessel and controlling the production by QC by batch test report before shipping. SBI Company guarantees the quality to meet with ASTM.
Uses of oxidized bitumen 150/5
Oxidized bitumen 150/5 uses in the chemical, raw material for bitumen coat, lacquers, varnishes, paper-pulp-board, textile processing, pavement ,crack seal and repairmen, civil works, bitumen coat for piping, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding, insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products. bitumen 150/5 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 bitumen 150/5 include roofing, pipe coating, hydraulic applications, 150/5 is mainly using in paint manufacturing and coating in hot area.
Application of oxidized bitumen 150/5
Before using bitumen 150/5 surfaces must be dry, clean and free of loose particles, curing products, irregularities, and slurry. If you use this types of bitumen without cleaning the area the bitumen 150/5 will easily remove.
