Oxidized Bitumen 90/40


Oxidized Bitumen 90/40

This is very special grade of Blown Bitumen because it has softening point of 90 c but the penetration must be 40 in normal position when the softening point is 90 c the penetration would be about 20 and only the factories who have good skill and experience in field of bitumen producing and have good facilities too have ability to produce blown bitumen 90/40.

its harder than penetration bitumen too but more flexible than other grades of blown bitumen.

we are producing it in our factory reactors from vacuum bottom with blowing hot air way but with a little a little different from producing other grades of Oxidized bitumen.

Oxidized Bitumen 90/40 uses

This grade of Oxidized bitumen like other grades is using in bitumen, insulation, isolation, asphalt, waterproofing, coating, roofing felt, and other industries that using blown bitumen but follow different in softening point and penetration some the industries who needs more penetration in 90 centigrade softening point will order this grade of blown bitumen to Asia Bitumen.

Oxidized bitumen 90/40 using way

like other grades of Oxidized bitumen or Blown bitumen before using it must warm it till 200 centigrade and then it will melt and would be usable for different industries.

Oxidized bitumen 90/40 packing

Packing of Blown bitumen 90/40 must be heat resistance because we must fill them when Oxidized bitumen is completely hot so the packing kind would be Kraft paper, poly bags and carton boxes with weight of 25 kg.
