Oxidized Bitumen 75/35 Also known as blown asphalt 75/25, oxidized asphalt 75/25 is Semi Solid grade of pure petroleum bitumen. As other oxidized bitumen grades .This product manufactured by air-blowning through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business.
Heated Penetration Grade bitumen under controlled environment is blown with air which controls the oil content in the bitumen while it oxidized. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.
Blown asphalt 75/25 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 75/25 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 blown asphalt 75/25 include roofing, pipe coating, portland cement pavement, hydraulic applications, paint manufacturing.
All Petroleum air blown asphalt based products, refined from blowing hydrocarbon with special attention to temperature and pressure of blowing tower. We export all blown grade of bitumen, including air Blown Asphalt 115/15 and 150/5 for soft grades at 75/25.
