BAKHTAR Bitumen Oxidized Bitumen  105/35


Description of blown bitumen/ Oxidized Bitumen 105/35

BAKHTAR Bitumen Blown bitumen 105/35 is of very high grade of oxidized bitumen which is utilized in  bonding compounds as hot melt adhesive at an application rate of approximately 1 Kg/m3 to bond the preformed sheets together and to structure which is made by Oxidized bitumen 60/70 by hot air. Blown bitumen 105/35 / Oxidized Bitumen is a semi-solid oxidized grade of pure petroleum bitumen produced by air-blowing through an asphalt flux. Special physical properties of this grade is applicable in different applications of construction industry.
BAKHTAR Bitumen Industrial Group company warranties the quality of BAKHTAR Bitumen oxidized bitumen / blown bitumen 105/35 with the arrangement of the international inspector to check quality and quantity of the BAKHTAR Bitumen 105/35 during the loading on container and during production inspection by QC with batch test report pre-delivery shipping. BAKHTAR Bitumen Company guarantees the quality to meet with ASTM Standards.

Applications of blown bitumen 105/35 

Blown bitumen 105/35 is utilized in chemical, fuel, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, paint, crack seal and repairmen, civil works, roofing, construction business, sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, rubber and plastic productions. The BAKHTAR Bitumen 105/35 are used for paving, asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, the base for synthetic turf, typical uses for bitumen 105/35 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint production. BAKHTAR Bitumen Blown bitumen 105/35 is used in construction insulation and isolation bitumen membrane sheet. Also in Car undercoating Automobile industry blown bitumen / Oxidized Bitumen is specially required. Vehicle undercoating material is normally of Oxidized Bitumen. Bitumen provides excellent waterproofing, dust proof and noise proof for automobile undercoating.

How to Apply Oxidized Bitumen 105/35

BAKHTAR Bitumen Oxidized Bitumen 105/35 shall be heated with double temperature against the softening point to be able to have very fine flow and viscosity. Before manipulation of blown bitumen 105/35, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, dust and any dirt.

Storage/handling Conditions of blown bitumen / Oxidized Bitumen 105/35 

BAKHTAR Bitumen 105/35 is guaranteed for the period of 10 years at multi-time heating and cooling conditions, please refer to MSDS Standards for further information.
