bitumen 75/25
General description of oxidized bitumen 75/25
Bitumen 75/25 is desire grade of Palestine, Lebanon, Syria and Jordan weather and normally exporting in open top 200Kg steel drum.It is mostly using in sealing of basement , foundation and shelters in this zone.It is belong with other softer grade of bitumen and increasing softening point of bitumen and viscosity also adhesion.
General uses of bitumen
Oxidized Asphalt 75/25 uses in isolation and insulation and concrete surface coating, pipe coating, asphalt shingle, bottom sealing of carpet, paint and primer, mastic and membrane roof sheet, laminate and adhesive, roofing and flooring and enamel.
Packing of 75/25
The ATDM is manufacturer of blown asphalt binder in various packing including kraft bag, meltable plastic bag, drum and bulk blown Oxidized Asphalt from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached.
The ATDM can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The oxidized asphalt grade 75/25 means softening point is 75°c and penetration is 25 desimillimiter is produced in compliance and conformity to ASTM standard and meets the following specification.
Guaranty/warranty
ATDM guaranty the quality of blown bitumen 75/25 with arrangement of international inspector to check quality and quantity of the Oxidized Asphalt 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.
