Oxidized Bitumen 85/25

We are prominent manufacturer, supplier and exporter of Oxidized Bitumen 85/25 in Esfahan, Esfahan, Iran. At the bitumen production reactor, during the air acting, the mixture of the two Vacuum Bottom (VB) and Vacuum Silabes (VS) feedstock is put under a special degree of pressure and temperature between 200-300E C of which the hydrogen atoms content in bitumen molecular oxidize to oxygen of air, and obtains with higher hydrocarbons polymerization reaction that has lower penetration and higher softening points than the primary pure bitumen. This kind of bitumen 85/25 has the softening point of 85 and permeability of 25.

Recommend uses of bitumen 85/25

It is using as raw material for bitumen coat, roofing, insulation and isolation bitumen membrane sheet.

Surface preparation of asphalt 85/25

Surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.
